Title: Improved Fischer-Tropsch synthesis catalysts for indirect coal liquefaction: Quarterly technical progress report No. 7, 1 April 1987-30 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 product distribution of the three monomer catalysts was remarkably dependent on the nature of the support. The ruthenium catalyst supported on sodium Y zeolite had superior FTS performance relative to a conventionally prepared alumina-supported ruthenium catalyst during a 24-h run at 523 K with 1:1 H/sub 2/:CO synthesis gas at 1 atm. Its chain growth factor was higher (0.57 vs 0.47), methane selectivity lower (45 wt % vs 58 wt %), and olefin-to-paraffin ratio for light hydrocarbons higher (2.2 vs 1.3). The FTS results for the molecular sieve catalyst under the same reaction conditions were inferior with low chain growth parameter (0.23) and high methane selectivity (77 wt %). 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 cobaltmore » was also examined. 4 figs., 3 tabs.« less
