ABSTRACT:

The goal of SRI's research program is to narrow the FT product distribution through two methods of catalyst development. The first approach consists of the organometallic synthesis of multiatomic ruthenium and iron-ruthenium alkyl-carbonyl clusters, the reaction of these clusters with acidic alumina or silica-alumina supports and the activation and characterization of these surface-confined clusters by temperature programmed decomposition and infrared spectroscopy. This method will focus on the development of very active FT catalysts with low wax yield. In the second approach, conventional promoted and unpromoted Fe, Co, and Ru catalysts will be treated by uniform deposition of low submonolayer levels of chemisorbed sulfur. This method will focus on selectively suppressing methane production. Catalysts developed by both methods will be given common characterization measurements and tested for their catalytic activity and FT product distribution relative to a standard precipitated iron catalyst. Those catalysts that promise significant improvement in selectivity will be further evaluated in bench-scale laboratory tests under realistic FT reactor conditions. 23 refs., 6 figs., 6 tabs.
