Multi-stage ebullated bed coal-oil hydrogenation and hydrocracking process

Abstract

Abstract A process for converting solid carbonaceous materials into valuable chemicals by hydrogenating a slurry of the solid material with a pasting oil in a reaction zone containing an ebullated catalytic bed at temperatures in the range from about 750-950*F. and a total pressure in the range from about 1,000 to 4,000 psig, separating the reaction effluent into gaseous materials, char, pasting oil, and a heavy synthetic crude, freeing the crude from the phenolic compounds contained therein and further hydrogenating said synthetic crude in a second stage catalytic reaction zone to produce a light synthetic crude and wherein a portion of the products of the process are used to supply some of the hydrogen requirement of the system.
