In order to make up a simulator to support the development of coal partial hydropyrolysis process, material balance of the reaction was investigated precisely. Amount of H_2 evolved by pyrolysis under inert gas atmosphere was found almost equal to that of (CO+2CO_2), therefore, most of H_2 seemed to be generated through water gas reaction and shift reaction. CH_4 seemed to be stable even at 1073K and 7.1MPa of H_2, its generation was simply accelerated in proportion to H_2 pressure. Hydrocarbons, other than CH_4, were fundamentally unstable at 1073K and 0.93-7.1MPa of H_2, however the rate of decomposition of them were so slow that amounts of them evolved were apparently proportion to reaction time and H_2 pressure. BTX and naphthalene were increased apparently with H_2 pressure when the reaction time was less than 5s.
