以不同方式引入硅，研究了不同硅源对重整催化剂性能的影响。结果表明：催化剂载体中引入含硅分子筛导致重整催化剂的裂解活性提高，选择性变差，积炭速率提高；重整载体制备过程中引入硅后导致催化剂的比表面积下降，选择性变差，积炭量增大；重整催化剂在反应过程中受到硅污染后，催化剂的持氯能力变差，活性降低。硅中毒是不可逆的，不能通过常规再生的方法恢复催化剂的活性。

This paper described the influence of Si addition in different ways on the performance of reforming catalysts. Introduction of Si-containing molecular sieve in catalysts increases the cracking ac-tivity and coking rate,and lowers the selectivity. The experiment find that the addition of Si in carrier preparation leads to the reduction of specific surface area and selectivity of the catalysts and higher co-king rate and that after contaminated by Si during reforming reaction,the Cl-keeping capacity becomes poor and the catalyst activity is dropped as well. Si poisoning are irreversible and catalyst activity cannot be recovered through conventional regeneration method.
