The invention provides a coal hydrogenation gasification method. The coal hydrogenation gasification method comprises the following steps: introducing hydrogen into a catalyst to be activated, and generating activated hydrogen; and mixing the activated hydrogen and coal powder to have a gasification reaction. According to the coal hydrogenation gasification method, by virtue of a way of catalytically activating the hydrogen, active hydrogen free radicals are provided for the coal hydrogenation gasification process, and the active hydrogen free radicals are promoted to have a coupling reaction with a coal primary pyrolysis product, so that the hydrogenation degree of the coal primary pyrolysis product can be increased, and the yield of methane and light-weight oil products in the coal hydrogenation gasification product can be increased.
