PROCESS FOR THE RECOVERY OF USEFUL PRODUCTS FROM A LIQUID CARBON PRODUCED BY LIQUIDIFYING AND CARBON-CONTAINING MATERIALS USING A SOLVENT AND SEPARATING THEREFORE USING A PROMOTIC FLUID.

摘要

A coal liquefaction product is separated into an essentially solid free stream and a solid containing stream including the coal ash. The solid containing stream is hydrotreated, in the absence of added catalyst, and valuable clean fuel components stripped from the hydrotreated stream. The combustibles content of the stripped solid containing stream is reduced by hydrotreatment, prior to stripping.
