摘　　要：根据锁匙反应机理中长链烷烃选择性异构化对催化材料孔道的要求,采用合适的改性手段,对FTZ-10分子筛进行处理,制备出酸性和孔道结构均满足异构化反应的催化材料,揭示催化材料表面酸性质与其异构化反应选择性之间的关联关系,并以正十二烷为模型化合物对该催化材料进行评价。结果显示:nC12转化率为91%时,异构体选择性达到80%。According to the requirements of the selective isomerization of long-chain alkanes in the key-lock mechanism on the pores of the catalytic material,appropriate modification methods was adopted to treat the molecular sieve FTZ-10.The prepared catalytic materials could meet the need of isomerization with suitable acidity and pore structure.The relationship between the surface acidity and the selectivity of isomerization was revealed.Using N-dodecane as the model compound,the catalytic materials were evaluated.The results showed that,when the conversion of n-C12 was 91%,the isomer selectivity reached 80%.
