Supported Ruthenium Carbonyls as Catalysts for the Hydrogenation of Carbon Monoxide and Dioxide.
Abstract
New supported ruthenium caytalysts have been prepared a) by diffusing Ru(CO)5 into the pores of faujasitic zeolites, and b) by sorbing ruthenium carbonyl cluster compounds onto oxide supports. After thermal activation, the supported ruthenium systemes catalyse the hydrogenation of carbon monoxide to mixtures of paraffins and olefins, but the hydrogenation of carbon monoxide hydrogenation results in typical Anderson-Schulz-Flory (A-S-F) product distributions, ie. low in C2 and C3 hydrocarbons, carbon dioxide hydrogention gives a product distribution which is not depleted in C2 and C3 hydrocarbons. Possible reasons for the fundamentally different product distributions obtained for the two carbon oxides will be discussed. Use of promoters and variation of conditions to optimize olefin content and to induce shape selectivity will also be discussed.
