Two-stage coal liquefaction process
Abstract
An improved SRC-I two-stage coal liquefaction process which improves the product slate is provided. Substantially all of the net yield of 650°-850° F. heavy distillate from the LC-Finer is combined with the SRC process solvent, substantially all of the net 400°-650° F. middle distillate from the SRC section is combined with the hydrocracker solvent in the LC-Finer, and the initial boiling point of the SRC process solvent is increased sufficiently high to produce a net yield of 650°-850° F. heavy distillate of zero for the two-stage liquefaction process.
