Abstract
An improvement in a process for producing hydrocarbons which boil in the gasoline or diesel fuel range from coal where the coal is reduced to a particle size below 2 mm, mixed with oil to form a pumpable pulp which is contacted with hydrogen in a hydrogenation zone resulting in a liquid fraction and a high melting residue fraction is disclosed. The invention resides in removing the high melting residue to a gasifying vessel to which is introduced granular coal of particle size of 3-50 mm. To the gasifying vessel is added a gasifying agent, e.g., water vapor alone or in admixture with oxygen which flows in countercurrent to the direction of the granular coal. As a result of the process, a gasification product is obtained comprising hydrogen and carbon monoxide.
