摘　　要：利用热重分析仪考察了铜川煤的热解及催化加氢热解行为.实验发现,Y分子筛催化加氢热解的第二热解阶段的峰温比原煤氮气下热解降低约85℃,热解转化率相对提高9.8%.NiS有利于热解转化率的提高,其催化加氢热解的转化率比原煤氮气下热解相对提高了13.8%,峰温降低约42℃.经动力学计算发现,催化剂的加入降低了热解反应的活化能.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%, and the second peak temperature decreased by 85 C compared with the pyrolysis under N2. NiS was effective for increasing conversion rate. The NiS catalytic hydropyrolysis conversion rate increased by 13.8%, and the second peak temperature decreased by 42 C compared with the pyrolysis under N2. The kinetics results showed that the coal added catalyst had lower activation energy than the raw coal.
