中文摘要：分子筛是实现低碳烯烃高活性和选择性的关键，本文从分子筛子催化裂化的机理入手，从烃的活化、裂解反应的动力学研究以及非骨架铝（EFAl）的影响三个方面对多年来关于分子筛在催化裂化增产低碳烯烃中的机理研究工作做出综述，从而为提高催化裂化增产低碳效率的研究提供一定的参考。
英文摘要：The molecular sieve is the key to realize the low carbon olefin with high activity and selectivity. This paper starts with the mechanism of catalytic cracking of molecular sieve. The mechanism of molecular sieves in catalytic cracking of low carbon olefins has been reviewed from three aspects of hydrocarbon activation, kinetics of cracking and extraframework aluminum specieskinetics. It will provide some reference for the research on increasing the production of low carbon efficiency in catalytic cracking.
