Hydrogenation of both coal and coal tar produces a wide variety of products, depending on the method of operation. Aviation gasoline, motor gasoline, diesel oil, fuel oil, illuminating oils, and lubricating oils have been made from coal and coal tar. Byproducts include gaseous hydrocarbons, sulfur, phenols, wax, and aromatic hydrocarbons.

The use of nascent hydrogen from hydriodic acid at 270°C gave 60% of the weight of the coal as oil. A fundamental improvement is achieved by the division of the hydrogenation process into two stages—namely, (1) liquidphase hydrogenation and (2) vaporphase hydrogenation. This twostage process for the hydrogenation of tar proves useful also ...
