Previous results for zeolite-supported Ru prepared by ion-exchange suggested a possible effect of the nature and concentration of the neutralizing cations in the zeolite on the catalytic properties of the metal. The interpretation of these results were complicated by the fact that a series of zeolites with different Si/Al ratio was used. This paper reports the results of a study of a series of RuY catalysts prepared from NH/sub 4/Y, LiY, NaY, KY, RbY, and CsY zeolites. The nature of the group IA cations was found to have little effect on chemisorptive properties and on the activity and chain growth probability in CO hydrogenation on Ru. However, the nature of the cations produced changes in secondary reactions of primary olefinic products as a result of differences produced during catalyst preparation in Ru distribution in the zeolite crystallites and of possible modifications of the acid sites generated during reduction of the Ru. 57 references.
