Conversion of Cellulosic Wastes to Liquid Hydrocarbon Fuels: Vol. 4, Slurry Phase Synthesis of Liquid Hydrocarbon Fuels from Biomass Pyrolysis Gas Using Iron Catalysts: Final Report

摘要

An experimental assessment of liquids and iron based catalysts for use in a Fischer-Tropsch slurry reactor has been conducted. The best catalyst/liquid combination was found to be a 48Fe/4.8Cu/47.2Kieselguhr catalyst in Chevron Refined Wax 143. At the optimum operating conditions of 300 deg C, 200 psig, using a 5 weight % catalyst slurry with a molar H sub 2 /CO feed ratio of 0.5, the yield of product was 118 mg/g-cat/h. Five different catalysts were tested in their ability to produce diesel type fuels from biomass pyrolysis gas. The catalysts tested, in order of decreasing product yield, were: kieselguhr supported, potassium promoted alumina supported, potassium promoted unsupported, unsupported, and alumina supported iron. A two-level factorial study using temperature, pressure, H sub 2 /CO feed ratio, and catalyst concentration in the slurry as factors was also performed. (ERA citation 12:010996)
