<p>Essentially solid carbonaceous material, such as coal (R), is rapidly converted to a high percentage of liquid hydrocarbon products by first reacting said material with an acid (16) to form carbon addition products which then are reacted with a Group V halide ion-acceptor system (super-acid system) (22), the acid content of which is greater than the Group V halide content, and thereafter with a hydrogen donor source (26). All phases of the process may be carried out at atmospheric pressure and relatively low temperatures, thus making said process far more economical than known coal liquefication processes. </p> |
