Abstract:
A process for catalytic hydroconversion of heavy hydrocarbon feed materials at least partially derived from organic municipal solid waste(organic-MSW) material to produce lower boiling hydrocarbon liquid products, the process comprising:(a) providing a feed material containing at least 50 wt. % chemically digested organic-MSW material which has been chemically digested in a polar acidic organic liquid and contains mainly aromatic and non-carbonyl compounds; reacting said feed material with hydrogen and a suitable hydroconversion catalyst in a reactor under reaction conditions of 600-860.degree. F. (315-460.degree. C.) temperature, 1000-3000 psig hydrogen partial pressure, and fresh feed rate of 20-60 lb/h/ft.sup.3 reactor volume, hydrocracking the feed material and generating an effluent material containing vapor and liquid portions;(b) phase separating said effluent material into its vapor and liquid portions, purifying said vapor portion and recovering hydrogen for recycle to the reactor; and(c) fractionating the effluent liquid portion into desired component fractions based on their normal boiling ranges, and withdrawing hydrocarbon liquid fraction products having a boiling range IBP-975.degree. F.
