摘  要:以天然矿物煤矸石为原料,在水热体系中合成了ZSM-35沸石,利用XRD、SEM、IR及CO加氢合成低碳烯烃反应,对沸石产品的结构及性能进行了测试。结果表明,利用煤矸石合成的ZSM-35沸石与化工原料合成的ZSM-35沸石类似,均具有良好的结晶度和CO+H2催化性能。Zeolite ZSM35 was synthesized with high crystallinity by using coal gangue,a natural mineral of kaolinite type,as a raw material in a hydrothermal systemThe asmade ZSM35 samples were identified by means of XRD,SEM and IR,and the results showed that the samples had as excellent physical properties as those of ZSM35 prepared with chemical reagentsThe catalytic properties were characterized in the reaction of CO hydrogenation for making light olefins,with a CO conversion rate of 616% and a selectivity for C2~C4 olefins of 103%
