The article is devoted to the issues of the current state of obtaining environmentally friendly liquid biofuel (bio-oil) from lignocellulosic biomass by its thermochemical conversion, as well as the prospects for the development of this direction in the near future. At present, thermochemical conversion of plant biomass (fast pyrolysis), which contains a large amount of lignocellulose, into liquid biofuel is one of the developing directions for involving unconventional energy sources into the energy balance of Ukraine. In this regard, it is of interest to assess the current state of the development of industrial production of liquid biofuel from plant biomass lignocellulose and further prospects in this branch of bioenergy. For this purpose, based on the study of scientific bibliography concerning the problem of liquid biofuel production, the existing experience of various countries in the industrial production of biodiesel fuel by the fast pyrolysis method is analyzed and the possibility of using lignocellulosic biomass as a raw material for its production is shown. It also provides information on technologies that have reached the industrial level. It has been established that the technology for producing biofuel from lignocellulosic biomass is widespread in many countries of the world. The paper describes the technological scheme of fast pyrolysis of wood and the main stages of production. It is shown that using the technology of thermochemical conversion of lignocellulosic biomass, it is possible to obtain a high-quality hydrocarbon product - bio-oil, and a description of the main advantages of this product is given. As a result of the work, it was established that the technology of bio-oil production from lignocellulosic biomass by the method of fast pyrolysis has broad prospects for further development. The results obtained by the authors of the article can be used in the further study of issues related to the thermochemical conversion of biomass into liquid biofuel. Ref. 12.
