Pyrolysis and catalytic hydropyrolysis of Tongchuan coal were studied using TG analysis． Y zeolite was effective for reducing pyrolysis temperature and increasing conversion rate．The Y zeolite catalytic hydropyrolysis conversion rate increased by 9．8 7／6，and the second peak temperature decreased by 85 C compared with the pyrolysis under N 2．NiS was effective for
increasing conversion rate．The NiS catalytic hydropyrolysis conversion rate increased by 1 3．8 7／6，and the second peak temperature decreased by 42 C compared with the pyrolysis under N 2．The kinetics results showed that the coal added catalyst had lower activation energy than the raw coal.
