摘　　要：催化剂的酸性中心类型、酸强度、酸密度和酸性位点分布已成为人们关注的主题。在分子筛催化剂中,B酸和L酸中心同时存在于孔道内部和外表面上,这些有效活性中心的类型和酸性质是分子筛催化活性的关键参数。依据当前的研究现状,综述了正丁烯骨架异构化的反应机理、分子筛催化剂的异构化活性中心以及异构化性能受酸强度、酸密度和酸性位点分布的影响。The acid center type,acid strength,acid density and acid site distribution of catalysts have been the subject of much attention.In molecular sieve catalysts,both B acid and L acid sites exist in the inner and outer surfaces of the channels,the types and acid properties of these effective active sites are key parameters of the catalytic activity of molecular sieve.According to the current research status,the reaction mechanism of 1-butene isomerization,the isomerization active center of molecular sieve catalyst were introduced,and the influence of acid strength,acid density and acid site distribution on the isomerization performance was discussed.
