ABSTRACT:

The work supported by this grant can be grouped under three headings: a comprehensive study of RuY, Ru supported on zeolites having a range of Si/Al values, and alkali promotion of Ru. NaY-supported Ru catalysts have been prepared by incipient-wetness (I.W.) (using RuCl sub 3 ), ion-exchange (I.E.) (using Ru(NH sub 3 ) sub 6 Cl sub 3 ), and vapor-impregnation (V.I.) (using Ru sub 3 (CO) sub 12 ). The resulting catalysts were extensively studied by chemisorption, atomic absorption, IR, ESCA, and catalytic reaction (especially F-T). Significant differences were found depending on the method of preparation. These differences were exhibited in both the physical and chemical characteristics of the catalysts. By variation of the preparation method and Si/Al ratio of the zeolite it is possible to develop a better understanding of how metal particle size and location, metal-zeolite interactions, neutralizing cation type and concentration, and the presence of zeolite acid sites can influence the catalytic properties of the supported metal. Ten papers are included in this final report and are grouped under the following headings: (1) chemisorption characteristics; (2) electronic state of Ru; (3) hydrogenolysis properties of NaY-supported Ru; and (4) Fischer-Tropsch synthesis. All papers have been processed for inclusion in the Energy Data Base.
