INTRODUCTION
The scale on which modern industry uses materials
and energy not only led to the substantial depletion of
fossil resources but also caused the accumulation of the
big amount of wastes, which are hazardous to the
environment. In 1980 IUCN (International Union for
Conservation of Nature), UNEP (United Nations
Environment Program) and WWF (World Wildlife
Fund) addressed this problem by developing the World
Conservation Strategy for Sustainable Development [1].
In September of 2015, the UN proposed 17 goals of
sustainable development, which were adopted by 70
countries [2]. Among these 17 goals, 9 can be achieved
with the help of plasma chemistry: "zero hunger", "good
health and well-being", "clean water and sanitation",
"affordable and clean energy", "decent work and
economic growth", "sustainable cities and
communities", "responsible consumption and
production", "life below water", "life on land".
Among the goals of sustainable development, the
minimization of the use of fossil fuels and their
replacement with the renewable sources of energy is one
of the most important for ecology, society and
economics. The switch to the renewable biomass can
lead to an ecologically beneficial reduction in the
emission of carbon, chemicals and liquid fuels.
However, it is widely recognised that the use of first-
generation biomass raw materials, such as corn or edible
oilseeds, is not a sustainable option in the long run
because it competes directly or indirectly with the
production of food. Therefore, the European Union is
aimed at the use of second-generation biomass raw
materials, which includes lignocellulose, waste oils and
fats [3]. One of the prioritised ways of achieving the
objective of affordable and clean energy is the
processing of lignocellulosic biomass into biofuels, but
the pace of development of this area is very slow [4]. A
major barrier to increasing the scale of biofuels
production lies in the disadvantages of two main ways
of processing lignocellulosic biomass: thermochemical
and biotechnological.
The biotechnical method of biofuel production is
based on using the microorganisms for the processing of
biomass into the desired product. This technology is
used successfully to obtain ethanol from plant sugars
and starches, but it faces significant challenges in the
transition to the more complex raw materials, such as
lignin and cellulose, and while attempting to produce
more sophisticated biofuels than ethanol [5]. Biological
agents used for the processing of raw materials are
selective to the composition of these raw materials,
sensitive to process conditions, and their reuse is
complicated. Complex raw materials need to be
additionally pretreated by the toxic substances, such as
acids and alkalis, for the biotechnical processing. This
treatment leads to the formation of toxic wastes in the
raw materials, which poison both the microorganisms
and the environment. At this stage of technology
development, the performance of the biotechnical
processing of lignocellulosic feedstock is low and is not
able to provide the required rate of biofuel production
growth.
The modern thermochemical technology of
lignocellulosic biomass processing requires much
higher temperatures than biotechnological methods
(over 700°C for pyrolysis and 1000°C for gasification).
A significant disadvantage of the thermochemical
technologies is low energy efficiency. It is also worth
noting that the use of high temperatures not only
complicates the design of processing devices and
requires the increase of safety requirements, but also
decreases the selectivity of the raw materials conversion
and leads to the emergence of byproducts. Therefore,
the traditional thermochemical (temperature> 700°C)
and traditional plasma-chemical (temperature> 1000°C)
(which is based on the ideas of thermochemical
conversion using plasma torches) processing of biomass
leads to the appearance of the unwanted byproducts and
wastes. In the case of catalytic conversion, a high
content of impurities in the initial raw biomass
negatively affects the yield and longevity of catalysts.
As of today, the discussion is open on the
development of principles behind the construction of
new technologies for the conversion of substances,
which are known as "green chemistry", which is a
departure from the traditional evaluation of the
effectiveness using the chemical yield to the assessment
of the cost-effectiveness based on the lack of hazardous

waste and non-toxic and/or hazardous substances.
"Green chemistry" has to transform the raw materials
(preferably renewable), exclude hazardous waste, and
use no toxic agents in the production of chemical
products and in their application [6]. There should be
the development of processes involving H2, O2, CO,
CO2, NH as a direct source of atoms H, O, C and N in
the production of fine chemicals. The quantitative
measure of the environmental acceptability of chemical
technology is E factor, which is defined as the ratio of
waste weight to the weight of a target product. Waste
includes everything that is not a target product [6].
Developed over the past decade chemo-catalytic
and/or biocatalytic integration technologies of the
"green chemistry" have not yet led to the large-scale
processing of lignocellulosic biomass into synthesis gas,
and do not fully meet the requirements of sustainable
development [5].
In recent years, very promising results have been
obtained in the study of the reforming of hydrocarbons
into synthesis gas in plasma-catalytic systems. These
systems are the improvement over the thermochemical
systems and have gas-discharge plasma used
additionally as a catalyst. The main result, which gives
reasons to consider plasma-catalytic approach as a
promising new alternative to traditional conversion
technologies with regards to the Arrhenius kinetics of
chemical reactions, is the reduction of the temperature
of the reforming process by several times.
The plasma-catalytic approach uses active particles
(OH, O, H, Ai
+
, Aj
-
, e, Ak
*e,v,r
, hν), which are generated
from the non-toxic and/or safe reagents in the plasma to
initiate the chain reactions of renewable biomass
conversion at low temperatures (~ 250...350°С).
Renewable biomass can be converted directly into
hydrocarbons (lower olefins, alkanes and aromatic
substances), which form the basis of petrochemical
plants raw materials, or into synthesis gas, which can be
converted into liquid fuel or chemicals [7] using
established technology (Fischer-Tropsch process,
methanol synthesis).
This work is devoted to several topics: further
experimental research of hybrid plasma-catalytic system
with the gas discharge generator of the wide-aperture
flow of non-isothermal plasma, the investigation of
some features of the kinetics in a plasma of wide-
aperture rotating gliding discharge using numerical
modelling, the comparison of chemical kinetics during
thermochemical reforming and reforming stimulated by
the additional injection of radicals that work as the
seeds of the chain chemical processes of reforming.
1. METHODS AND EXPERIMENTAL SETUP
Partial oxidation reforming of hydrocarbons is the
most energy-efficient and economical reaction pathway
for use in the conversion methods that utilise electric
energy. This is especially important for the plasma-
chemical reforming methods that use electric energy.
The reason for this is that in modern power plants the
production of one unit of electrical energy requires three
units of chemical energy. Fig. 1 shows the schemes of
two hydrocarbon conversion approaches are present in
plasma-chemistry: plasma reforming and plasma-
catalytic reforming.
In plasma approach, the hydrocarbon and oxidant
are introduced directly into the discharge area after
which the activated mixture is injected into the reaction
chamber. Such approach leads to the appearance of the
exothermal reactions in the discharge area, which
increase the rotational temperature of heavy plasma
components and cause the decrease of plasma non-
isothermality and drop in the yield of desired products
[8,9]. In plasma-catalytic approach, only a part of the
oxidant is introduced into the discharge area and the
activated oxidant is injected in a form of radicals into
the reaction chamber, which has the separate injection
of hydrocarbon. This approach results in the generation
of the non-isothermal plasma, which provides the
increased selectivity of desired product. Discharge can
be used to activate a part of the oxidant while the rest of
the oxidant is introduced into the reaction chamber
together with the hydrocarbon.
A discharge chamber, which is attached to the
reaction chamber [10-13], is designed for the plasma-
catalytic approach to the hydrocarbon conversion.
Plasma is generated using wide-aperture rotating gliding
discharge [14-18]. The discharge is powered using DC
power source. Fig. 2 shows the discharge chamber, gas
flow directions and wide-aperture rotating gliding
discharge, which was used for the plasma-catalytic
conversion of hydrocarbons.
Fig. 1. Schematic representation of plasma and plasma-
catalytic approaches to hydrocarbon conversion
96 % ethanol was used as a model hydrocarbon
during the plasma-catalytic reforming of hydrocarbons,
atmospheric air, which was supplied using a
compressor, was used as an oxidant. The system for
plasma-catalytic reforming of hydrocarbons into the
synthesis gas was designed for the output power of
25 kW and tested using 53.3 g/min (25 kW) ethanol
flow. The experimental laboratory studies of hybrid
plasma-catalytic reforming of ethanol were conducted at
lower output power. Optical emission spectroscopy was
used for the study of plasma. Gas chromatography was
used for the study of gas-phase products. Numerical
modeling was used for the study of kinetics of plasma
and thermochemical reforming.
2. EXPERIMENTAL RESULTS
The hybrid plasma-catalytic approach can become a
new alternative to the traditional conversion
technologies. The plasma-catalytic approach uses the
128 ISSN 1562-6016. ВАНТ. 2017. №1(107)
active species (OH, H, O), which are produced inside
plasma from the non-toxic and/or safe reagents, to
initiate the chain reactions of renewable biomass
conversion at a low temperature (~ 250…350°С).

flows and wide-aperture rotating gliding discharge

Fig. 3 shows the dependence of hydrogen energy
yield on the reaction chamber temperature during the
plasma-catalytic reforming of ethanol. Discharge power
is 24 W, discharge current is 60 mA, air flow is 7 l/min
(the amount of air is 40 % higher than required by the
stoichiometry of ethanol partial oxidation reaction),
ethanol flow is 4.3 g/min (2 kW). Discharge activated
only 20 % of the total amount of air. Maximum
hydrogen (desired product) energy yield was reached at
the temperature of 250°С, which is significantly lower
than for the traditional thermochemical (> 700°С) and
plasma-chemical (> 1000°С) hydrocarbon conversion.
Fig. 4 shows the comparison between the hydrogen
energy yields and conversion efficiency of the hybrid
plasma-catalytic reforming of ethanol (the best results)
and other methods of hydrogen production that utilise
electrical energy. Comparison of hydrogen production
methods includes both commercial methods, such as
water electrolysis [19] and biomass gasifiers based on
the Westinghouse/AlterNRG plasma torches [20], and
results of the most advanced studies on the production
of hydrogen from ethanol using low temperature
atmospheric pressure plasma, such as Laval nozzle arc
[21], dielectric barrier discharge [22], MW discharge
[23], arc discharge [24], GEN3 plasma source [25],
submerged nanosecond pulsed discharge in the water
solution of ethanol [26].

The hydrogen energy yield of hybrid plasma-
catalytic ethanol reforming is the highest in comparison
with the other methods [19-26]. The ratio of the reactor
power output to its volume is approximately 100 kW/l.
The hybrid plasma-catalytic approach can be used to
solve the existing problems of the traditional renewable
biomass reforming methods.
3. RESULTS OF NUMERICAL MODELING
The kinetics of plasma-chemical processes in the
plasma of wide-aperture rotating gliding discharge and
chemical kinetics of ethanol conversion into synthesis
gas were calculated via ZDPlasKin programme code
[27, 28]. ZDPlasKin allows the simulation of plasma
kinetics by taking into account the preliminary set of
input parameters of the studied system (temperature,
pressure, the initial concentration of reagents etc.).
During the calculation fulfilled for the plasma of moist
air, the database used for the calculation comprised of
900 chemical and electron-molecular reactions
involving 83 components. Time sampling step was
10
-12
s. The time interval for the calculation of changes
in the concentration of plasma components at the time
evolution was 10
-3
s. It is significantly higher than the
time of the exposure of gas to the current channel of gas
discharge considering the experimental data: the rate of
gas flow was ~ 10
3
cm/s, wide-aperture rotating
discharge is a transverse discharge with the diameter of
current channel ~ 10
-1
cm, respectively the time of gas
exposure to the current channel is ~ 10
-4
s.
This list of reactions is based on a mechanism
proposed in [29]. Because the experimental data
confirms that the rotational temperature is high enough
(~ 2500 K), all the reaction of the oxidation of
atmospheric nitrogen were included to the list of
reactions. The mechanism was complemented by the
reactions, which involved such species as N2O, NO2,
NO3, N2O5, N2O
+
, NO2
+
, N2O
-
, NO2
-
NO3
-
, the rates of
chemical and electron reactions were taken from [30].
According to the experiment, the electric field in the
plasma zone varied in the range of 100...500 V/cm,
which necessitated the addition of dissociation reactions
by electron impact of such components as H2O, NO2
and HO. At the same time, in this type of conversion,
the air with the addition of H2O is the plasma gas, which
is why the list of reactions involving H2O and its
derivatives was added to this mechanism. The list of
reactions involving H2O was composed using [31, 32].
Typical time dependencies of the concentrations of
N2, N, O2, O, O3, H, OH, H2, which are calculated for
the plasma of gas discharge – [Ai](t), are shown in
Fig. 5.
Provided dependences [Ai](t) show that during the
experiment the setting time of the fixed values [Ai] of
O, H, and OH radicals corresponds to ~ 10
-4
s, and the
degree of the dissociation of molecular oxygen O2 and
water H2O is ~ 10
-2
.
During the calculation of chemical kinetics in the
reactor zone of the experimental system [10], the
database contained 130 chemical reactions involving 30
component [33]. Time sampling step was 10
-6
s. The
time interval for the calculation of changes in the
concentration of plasma components was 10
-3
s. The
time interval for the calculation of changes in the
concentration of the gas components at the outlet of the
reactor zone (Fig. 6) was equal to 10 seconds.
Fig. 5. Time dependence of concentrations of N2, N, O2,
O, O3, H, OH, H2 in plasma of gas discharge in air at
atmospheric pressure, 10 % humidity, 2500 K gas
temperature, and at 400 V/cm electric field

130 ISSN 1562-6016. ВАНТ. 2017. №1(107)
It is significantly higher than the time of the exposure of
gas to the reactor zone with regard to the experimental
data: the rate of gas flow is ~ 10
3
cm/s, typical reactor
size is approximately 10 cm, thus the time of the
exposure of gas to the reactor zone is ~ 10
-2
s.
The typical calculated time dependences of
C2H5OH, OH, O, H, O2, СН3СНО, СН4, CO, CO2, H2,
Н2О concentrations for the thermochemical conversion
of ethanol at 1100 K for 1C2H5OH/0.5O2/0.5H2O/2N2
initial mixture and at 523 K for
1C2H5OH/1O/0.5H/0.5OH/2N2 initial mixture are
shown in Fig. 6 and Fig. 7 respectively.
The comparison between the time dependences of
concentrations, which are shown in Fig. 6 and Fig. 7,
allows for the determination of the effect caused by the
stimulation of the thermochemical conversion using O,
H and OH radicals, which are the seeds of the chain
conversion process, injected from plasma into the
reactor zone. The comparison of the gas composition
calculated under conditions of full thermochemical
conversion of ethanol (see Fig. 6) at the outlet of the
reactor zone and reforming stimulated by the additional
injection of radicals (see Fig. 7) also shows the
existence of difference in the conversion mechanism,
which results in significant changes in the syngas ratio
[H2]/[CO].
CONCLUSIONS
The experimental and theoretical studies of plasma-
catalytic and purely thermochemical conversions of
ethanol show that:
1. Plasma-catalytic approach is an emerging
alternative to the traditional conversion technologies.
Plasma-catalytic approach uses active species (OH, O,
H) generated in the plasma from non-toxic and/or non-
hazardous reagents to initiate the chain reactions of
renewable biomass conversion at low temperature
(~ 500…600 K).
2. Plasma-catalytic approach confirms the concept of
sustainable development with the production of small
amounts of waste (~ n %).
3. Studies of chemical kinetics revealed differences
in the mechanism of the conversions that result in
significant changes in syngas ratio ([H2]/[CO]).

Работа посвящена изучению совместимости гибридной плазменно-каталитической конверсии жидких
углеводородов в сингаз с концепцией устойчивого развития. Результаты выполненных экспериментальных
исследований указывают на высокую эффективность плазменно-каталитической конверсии этанола в сингаз
с малым количеством отходов (несколько процентов от массы исходного сырья). Результаты проведенной
симуляции кинетики с использованием программного кода ZDPlasKin традиционной термохимической и
гибридной плазменно-каталитической конверсий указывают на некоторые отличия в их механизмах,
которые приводят к существенному изменению сингазного соотношения.

Робота присвячена вивченню сумісності гібридної плазмово-каталітичної конверсії рідких вуглеводів у
сингаз із концепцією сталого розвитку. Результати виконаних експериментальних досліджень вказують на
високу ефективність плазмово-каталітичної конверсії етанолу в сингаз з малою кількістю відходів (декілька
відсотків від маси вихідної сировини). Результати проведеної симуляції кінетики з використанням
програмного коду ZDPlasKin традиційної термохімічної та гібридної плазмово-каталітичної конверсій
вказують на деякі відмінності їхніх механізмів, які спричиняють істотні зміни сингазного співвідношення.

The results of the experimental investigations indicate the high efficiency of plasma-catalytic conversion of ethanol to syngas and the small amount of waste (a few percent of feedstock weight). The results of the simulation of the kinetics using ZDPlasKin code for traditional thermochemical and hybrid plasma-catalytic conversions indicate some differences in their mechanisms, which lead to the significant changes in the syngas ratio.
