ABSTRACT:
Disclosed is a two-stage process for the production of liquid hydrocarbons from coal. More particularly, disclosed is a two-stage coal liquefaction process wherein subdivided coal is substantially dissolved in a solvent in a first non-catalytic dissolving stage at the temperature in the range 750.degree. to 900.degree. F. In a second stage, the mixture of solvent, dissolved coal and insoluble solids is contacted with a hydrocracking catalyst at a critical temperature below 800.degree. F. The normally liquid portion of the hydrocracker effluent product has a surprisingly low sulfur content of less than 0.1 weight percent, a low nitrogen content of less than 0.5 weight percent, and a high API gravity of at least -3.
