| 摘 要： | 在连续流动固定床反应器上,以Ca/ZSM-5分子筛为催化剂,考察了氮气、一氧化碳、二氧化碳、合成气和水蒸气气氛对二甲醚制丙烯（DTP）反应催化剂的稳定性和丙烯选择性以及副产物选择性的影响,同时考察了失活催化剂再生后催化性能的变化。实验结果表明,反应气氛对DTP体系具有一定的影响。其中,以二氧化碳为反应气氛时催化剂稳定性最好,丙烯选择性最高,副产物选择性较低;一氧化碳、合成气、氮气的效果次之;水蒸气的效果最差。再生后催化剂的性能表明,CO2作反应气氛对DTP生成有利。

| Abstract: | Effects of reaction atmospheres(nitrogen,carbon monoxide,carbon dioxide,syngas and water vapor) on stability of the catalyst,selectivities to propylene and byproducts for dimethyl ether conversion to propylene(DTP) over Ca/ZSM-5 were investigated in a continuous flow fixed-bed reactor.Besides,the regenerated catalyst was also studied for DTP process.The results show that the catalyst exhibits best stability,highest propylene selectivity and lowest selectivities to byproducts in carbon dioxide atmosphere,fol... |
