Abstract
A series of Cu-based mixed oxides was investigated for the development of active Cu catalysts for the water gas shift reaction (WGSR), a technology that may find new applications in fuel cell and coal processing systems. Tri-metallic catalysts active for WGSR were obtained after high temperature calcination at 900°C and subsequent reduction. The results were compared with commercial Cu/ZnO/Al2O3 catalyst and prepared Ru/TiO2/Al2O3 catalyst. The spinel-type oxides had comparable CO conversion than well-known Cu/ZnO/Al2O3. Precious metal based WGSR catalyst showed higher CO conversion with substantially higher yield of methane. The Ru-based catalyst showed highest CO conversion ∼ 300°C achieving over 99% CO conversion. A trend was found between the TPR peak maxima of the major peak and the maximum CO conversion achieved by respective catalysts. This is an abstract of a paper presented at the 15th Annual Saudi-Japanese Symposium: Catalysts in Petroleum Refining and Petrochemicals (Dhahran, Saudi Arabia 11/27-28/2005).
