In order to study elemental reactions between coal and hydrogen, reaction of coal with hydrogen atom was investigated at 20-1000℃ under 1.0 and 760 Torr. Weight decreases of coal, caused by the reaction with hydrogen atom, were observed over 300℃. Main gas products from the reaction of coal with hydrogen atom were methane, carbonoxide, and carbondioxide. Amount of these produces were more than ten times larger than those from thermal decomposition. Liquid products increased with temperature. Increase of naphthalene with temperature implies that dealkyl reaction, occurred by addition of hydrogen atom on the ipso position of alkyl aromatic compound, is dominant at higher temperatures. The result agreed with our previous experiment using some model compounds.
