The effect of vanadium oxide as support and promoter on supported rhodium catalysts on the CO hydrogenation has been investigated at 0.15 and 4.0 MPa. Rh/V,O, reduced at 723 K has a good selectivity toward oxygenated products, especially C,-oxygenates, but has a low activity added as a promoter to catalysts consisting and stability. Vanadium oxide of rhodium supported on silica and alumina show...

The effects of potassium promoter for production of heavy hydrocarbons from syngas with silica- supported cobalt catalysts has been studied. After preparing the catalysts in accordance with the sol-gel method, they were subjected to various tests by using a small steely micro-reactor and capable of operating in diversified situations, such as stable temperature range, flow rate, space velocity,...

CO oxidation, one of the most important chemical reactions, has been commonly studied in both academia and industry. It is good probe reaction fields surface science heterogeneous catalysis, by which we can gain a better understanding knowledge mechanism. Herein, oxidation state Cu species to seek insight into role copper activity. The catalysts were characterized XRD, N2 adsorption-desorption,...
