Abstract
An effort is under way at PETC to study the potential of reducing pressure in coal liquefaction. The objective of this effort is to reduce pressure and maintain overall coal conversions, yields and product quality. Several observations have been made during this study and have been reported. The potential for reducing pressure appears to be tied to a combination of solvent quality and catalyst concentration. Other observations were made concerning the hydrogenation of products from reactors containing coal. This study investigates hydrogen consumption in coal liquefaction as well as coprocessing of a coal/oil mixture.
