An extensive research program was conducted to ascertain ways to improve oil yields and process economics of direct coal liquefaction. The effects of removing heteroatoms from the solvent, pretreating coal by several techniques (including solvent extraction, oxidation, grinding, and ion exchange), and beneficiating coal by removing mineral species were investigated in both catalytic and noncatalytic coal liquefaction reactions. Additionally, fundamental studies were carried out to explain the role of heteroatoms in catalytic coal liquefaction. The effects of process variables, catalysts and mode of catalyst addition, solvent properties, and recycle of SRC on oil production and coal conversion were also studied. 9 refs., 12 figs., 72 tabs.
