以无定形酸性硅铝材料ASA30和ZSM-35沸石为母体材料，通过复配制备了一系列组成不同的复合催化材料，并考察了其在1-己烯临氢异构化反应中的催化性能。利用N₂物理吸-脱附、NH₃-TPD和Py-IR等对复合催化材料的孔结构和酸性质进行研究。结果表明，复合催化剂的孔结构参数、酸类型、酸强度及强弱酸酸量随其组成发生有规律的变化。骨架异构化率及异构烷烃选择性最好的AZ-3/2在250℃就达到其最优异构化性能，骨架异构化率为84.81%，异构烷烃选择性为27.53%，异构烯烃选择性为57.28%，正构烷烃选择性仅为4.65%。此时L/B酸比例为2.3、中强酸/弱酸比例为5.26。

ASA30 zeolite and ZSM-35 zeolite,both amorphous acidic silica-alumina materials,are used as parent materials,a series of composite catalytic material with different compositions are prepared via compounding method,and their catalytic performance in the hydro-isomerization of 1-hexene is investigated.The pore structure and acidic properties of the composite catalytic material are studied by means of N₂ physical adsorption-desorption,NH₃-TPD and Py-IR.The results show that the pore structure parameters,acid type,acid strength and the amounts of strong and weak acids of the composite catalyst change regularly with its composition.AZ-3/2 composite catalyst with the best skeletal isomerization rate and iso-alkanes selectivity can reach its optimal isomerization performance at 250℃,over which the skeletal isomerization rate of 1-hexene reaches 84.81%,the selectivity of iso-alkanes is 27.53%,the selectivity of iso-olefins is 57.28%,and the selectivity of n-alkanes is 4.65%.The ratio of L acid to B acid of AZ-3/2 is 2.3,and the ratio of medium strong acid to weak acid is 5.26.
