Alkali Doped (Na, K) Cu/Cr2O3:Al2O3 Catalysts for Water Gas Shift Reaction

Abstract


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.
