在搭建的固定床实验台上对CaO和Fe（NO3）3复合催化锦界煤焦-CO2常压等温气化的反应特性进行了研究．结果表明：复合催化剂最佳质量添加比例为1％Ca、29／6Fe，且在最佳添加量下气化时间比原煤焦和单组分催化剂下的气化时间分别缩短了103rain和18rain，催化强度系数分别是原煤焦、单组分催化剂CaO和Fe（N03）3的5．71倍、1．65倍和2．04倍，气化温度降低了100K，气化温度降低程度介于单组分催化剂CaO和Fe（NO3）3之间；复合催化过程生成的部分Ca（NO3）2与CaO的活性不同，即Ca的催化强度与其前驱物的形式有一定关系；添加单组分催化剂的煤焦活化能与原煤焦的活化能基本相同，不同添加比例的复合催化剂的煤焦活化能增加的程度不同，且在最佳添加比例下增加程度最小，其值为15．4％．

The gasification characteristics of Jinjie coal char with CO2 under compound catalytic action of CaO and Fe(NO3)a were studied under isothermal and ordinary pressure conditions on a fixedbed experi mental system. Results show that the optimal mass addition of compound catalyst is 1% Ca+2% Fe, in which case, the gasification time can be reduced by 103 min and 18 min respectively as compared with that of raw coal char and singlecomponent catalyst, and the catalytic intensity coefficient will be 5.71, 1.65 and 2.04 times of raw coal char, singlecomponent catalyst CaO and singlecomponent catalyst Fe(NOa )3, with a reduction of gasification temperature by 100 K, and a reduction of gasification temperature lying be tween singlecomponent catalysts CaO and Fe(NOa )3 ; the activity of partial Ca(NO3)2 produced under the compound catalytic action is different from that of CaO, that is, the catalytic intensity of Ca has a certain relationship with the form of its precursor; the activation energy of coal char with addition of singlecom ponent catalyst is basically the same as that of raw coal char. Addition proportions of compound catalyst influence the increase degree of activation energy of coal char, and the minimum increase degree 15.4% is to be obtained at the optimal addition proportion.
