Abstract
A hydrocarbon liquid feedstock containing at least 50 wt. % chemically digested organic-MSW material is catalytically hydroconverted utilizing either a single stage or two-stage catalytic reaction process to produce desirable lower-boiling hydrocarbon liquid products. The catalyst can be either a particulate supported type catalyst such as containing cobalt and/or molybdenum and/or nickel on alumina support, or a dispersed slurry type catalyst containing mainly iron oxide with anions of molybdate, phosphate, sulfate or tungstate, and combinations thereof. Broad useful reaction conditions are 600-860° F. (315-460° C.) temperature, 1000-3000 psi hydrogen partial pressure, and fresh feed rate of 20-60 pounds/hr/ft,reactor volume. Effluent material from the final stage catalytic reactor is phase separated and the resulting liquid portion is fractionated to produce the desired low-boiling hydrocarbon liquid products particularly useful as transportation fuels. If desired, the chemically digested organic-MSW feedstock can be blended with petroleum residua and/or particulate coal and/or mixed waste plastics and the blended feed material processed in catalytic two-stage reactors to produce similar desirable low-boiling hydrocarbon liquid products.
