Доповані лужними (Na, K) гідроксидами каталізатори Cu/Cr2O3:Al2O3 конверсії водяного газу
The effect of precipitating agent (alkali ions Na, K) on copper-chromium-aluminum systems has been examined. Catalysts precipitated by alkali ions present lower CO conversion in comparison with ammonia catalysts because of their higher crystallinity degree and harder susceptibility to reduction. Cat...

Chemistry, Physics and Technology of Surface| Summary: | The effect of precipitating agent (alkali ions Na, K) on copper-chromium-aluminum systems has been examined. Catalysts precipitated by alkali ions present lower CO conversion in comparison with ammonia catalysts because of their higher crystallinity degree and harder susceptibility to reduction. Catalysts obtained with NaOH are characterized by higher alkali metal concentration and by its uniform distribution on their surface as compared with KOH-derived ones. |
