摘要

采用原位合成法制备了 HY-SBA-15分子筛，并进行La改性。用XRD、N

吸附-脱附等表征分析，在小型固定床上考察了 La负载量、焙烧温度、时间对烷基化性能的影响，结果发现，最优制备条件是La负载量为10%、焙烧温度550℃、焙烧时间4.5h。 XRD、N

吸附-脱附表征分析La-HY-SBA-15分子筛有微-介孔结构，NH

-TPD表征分析La-HY-SBA-15分子筛主要为中强酸，Py-FTIR表征分析La-HY-SBA-15分子筛L酸比B酸多。

Abstract

HY-SBA-15 zeolite was prepared by in-situ synthesis method and was modified in La by impregnation method. La-HY-SBA-15 was characterized by XRD

adsorption-desorption and so on. The alkylation influence of load amount

calcination temperature

calcination time on La-HY-SBA-15 zeolite was investigated in a fixed-bed reactor. When load amount of La was 10%

calcination temperature was 550℃

calcination time was 4. 5h

the reaction of alkylation had the best performance. La-HY-SBA-15 zeolite had micro-mesoporous structures by characterization of XRD and N

adsorption-desorption

mainly had medium strong acid by characterization of NH

-TPD

had more Lewis acid than Bronsted acid by characterization of Py-FTIR.
