摘　　要：以课题组独创的催化剂添加方式,实现了对煤的催化解聚.研究了锌基催化剂对内蒙褐煤催化解聚产物分布的影响.结果表明:催化解聚对产物的分布影响显著.相比原煤热解,催化煤解聚焦油产率提高26.88%,煤气热值提高30.79%,半焦比表面积提高80.65%.催化煤解聚相比原煤热解显示出一定的潜在优越性.An original creation catalyst adding way was proposed and it can promote the catalytic depolymerization of coal. Based on that, we studied the product distribution and charac- teristics of catalytic depolymerization of coal. The results show that compared to coal pyrolysis, the catalytic depolymerization of coal can promote tar yield increasing by 26.88%, promote gas calorific value increasing by 30. 79% and promote semi-coke surface increasing by 80. 65%. It shows that coal catalytic depolymerization has a certain advantages compared to coal pyrolysis.
