ABSTRACT:

The current research involves a study of the promotion effects of the neutralizing alkali cations on CO hydrogenation (under typical F-T conditions) over zeolite-supported Ru catalysts. During this quarter, a series of alkali zeolites were prepared by partial exchange of NH sub 4 Y and various alkali cations (Li sup + , Na sup + , Rb sup + ). These catalysts were characterized by atomic absorption and flame-emission spectroscopy. The concentration of NH sub 4 + cations was determined by Kjeldahl analysis. The transformations of olefins (propylene and butene) over these catalysts were investigated under similar conditions as those used for CO hydrogenation over Y-zeolite supported Ru catalysts. 4 refs., 3 figs., 3 tabs.
