制备了在反应温度下能够稳定存在的３种晶型ＺｒＯ２催化剂，并分别对它们作为合成气制低碳烯烃反应中的催化剂进行了考察。ＺｒＯ２评价结果表明，ＺｒＯ２催化剂的品型结构与反应中的催化性能有关联性，它们在反应中均对低碳烯烃有较好的选择性，单斜晶型有利于生成异丁烯，而其它两种晶型则有利于乙烯生成，几乎无Ｃ４烯烃的生成。 Three kinds of ZrO2 catalysts which can stably exist at the reaction temperature were prepared, and their catalysts were also investigated respectively as the catalysts for the synthesis of light olefins from syngas. The results of ZrO2 evaluation show that the type structure of ZrO2 catalyst is related to the catalytic performance in the reaction. Both of them have good selectivity to light olefins in the reaction. The monoclinic form is conducive to the formation of isobutylene, while the other two Crystalline is conducive to the formation of ethylene, almost no C4 olefin generation.
