Title: Improved Fischer-Tropsch synthesis catalysts for indirect coal liquefaction: Quarterly technical progress report No. 7 for the period 1 April to 30 June 1987

Abstract

Three monomeric supported ruthenium catalysts were evaluated for Fischer-Tropsch performance with 1:1 H/sub 2/:CO synthesis gas at 1 atm. This effort completes the FTS evaluation of a series of nine supported multiatomic and atomic ruthenium catalysts prepared via organometallic reactions of tetra- and hexaruthenium hydridocarbonyls and allyl monoruthenium carbonyl complexes with acid sites on three support materials, alumina, sodium Y zeolite, and molecular sieve. The ruthenium catalyst supported on sodium Y zeolite had superior FTS performance relative to a conventionally prepared alumina-supported ruthenium catalyst. Its chain growth factor was higher, methane selectivity lower, and olefin-to-paraffin ratio for light hydrocarbons higher. The results for the molecular sieve catalyst under the same reaction conditions were inferior with low chain growth parameter and high methane selectivity. The C/sub 2+/ hydrocarbon synthesis rates of all the ruthenium catalysts were comparable. The effect of high-level sulfur chemisorption on the FTS performance of alumina-supported cobalt was also examined. The untreated cobalt catalyst had higher activity and higher methane selectivity relative to the standard fused iron catalyst. 4 figs., 2 tabs.
