ABSTRACT:
The invention is an improvement in the process for hydrogenation of a finely divided coal and oil slurry wherein the improvement comprises subjecting the hydrogenation products to a first phase separation to obtain a liquid fraction and a gaseous fraction. The gaseous fraction is subjected to a second phase separation to obtain a liquid fraction having a boiling range between about 200.degree. C. and about 500.degree. C., which fraction is used to preheat the coal and oil slurry by direct mixing therewith.
