As shown in Fig., coal from hydrogenation yields phenols, BTXaromatics, olefines and higher nuclei aromatics, premium gasoline and diesel fuel (Jüntgen, 1982a).The first step of coaloil processing is distillation by which light oil, middle oil and heavy oil are produced. The processing of these fractions utilizes techniques well known in mineral oil refining.
