A process for the hydrogenation of coal and subsequent treatment of hydrogenated coal to produce useful fuels and chemicals which comprises comminuting coal ore to a particle size range of from about 150 mesh to about 250 mesh; hydrogenating the particulate coal in the presence of a hydrogenation catalyst and a source of hydrogen at a temperature of from about 100°to about 300°C. and a pressure of from about 500 to about 1,000 psi for a time sufficient to react hydrogen with the coal to form predominantly hydroaromatic coal; and recovering the hydrogenated coal. The hydrogenated coal is subsequently hydrocracked or pyrolyzed. The hydrogenated coal is hydrocracked at from about 500°to about 700°C. a pressure of from about 500 to about 2,000 psi for a time sufficient to crack the coal to produce benzene, toluene, xylene and gasoline. The hydrogenated coal is pyrolyzed at from about 400°to about 700°C., at a pressure of about atmospheric pressure and for a time sufficient to convert the coal to C1-C4 gaseous hydrocarbons, naphtha and tar.

A process for the hydrogenation of coal which comprises: (a) comminuting coal ore to a particle size range of from about 150 mesh to about 250 mesh; (b) hydrogenating the particulate coal in a hydrogenation zone in the presence of a hydrogenation catalyst in the vapor phase and selected from the group consisting of halides of zinc and tin, carbonyls of cobalt, iron, transition metals selected from Groups VI, VII and VIII of the Periodic Table, and mixtures thereof, and hydrogen at a temperature of from about 100°to about 300°C. and a pressure of from about 500 to about 1,000 psi for a time sufficient to react hydrogen with the coal to form predominantly hydroaromatic coal; and (c) recovering the hydrogenated, hydroaromatic coal from the hydrogenation zone.
