ABSTRACT:
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.degree. to about 300.degree. 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.degree. to about 700.degree. 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.degree. to about 700.degree. C., at a pressure of about atmospheric pressure and for a time sufficient to convert the coal to C.sub.1 -C.sub.4 gaseous hydrocarbons, naphtha and tar.
