Process of producing liquid hydrocarbon fuels from biomass
This patent describes a process for producing liquid hydrocarbon fuels consisting essentially of C/sub 7/-C/sub 17/ paraffinic hydrocarbons free of oxygenated compounds from an oxygen-containing biomass comprising: feeding comminuted biomass into a pyrolyzer heated to a temperature of from about 1,2000/sup 0/ to 2,000/sup 0/F to produce an intermediate synthesis gas containing in mole percent from 10 to 53 percent hydrogen, from about 6 to 60 percent carbon monoxide, from 5 to 39 percent olefins, from 6 to 33 percent paraffins, and from 4 to 26 percent carbon dioxide directing the unseparated intermediate synthesis gas into a catalytic reactor operating at about 500/sup 0/F 140 psig. It containing a catalyst consisting of an active ingredient selected from the group consisting of cobalt, ruthenium, nickel and iron disposed upon a compatible support structure selected from the group consisting of alumina, silica, kiesulguhr and diatomaceous earths. These form a water/alcohol binary and the liquid hydrocarbon fuel; and separating the liquid hydrocarbon fuel from the water/alcohol binary.
