Abstract: Soft template monomers are made from cheap organosilicone,and treated by the sol-gel method to generate a degree of polycondensation.It is explored whether the template which has undergone a certain degree of polycondensation can continue to play the role of mesoporous pore formation in the synthesis of hierarchical porous ZSM-5 molecular sieve.Thiophene alkylation reaction is used as the probe reaction to investigate the catalytic performance of the synthesized hierarchical porous ZSM-5 molecular sieve.The catalytic performance of hierarchical porous ZSM-5 molecular sieve is significantly higher than that of traditional ZSM-5 molecular sieve.Compared with the sample synthesized by template monomer,the performance of hierarchical porous ZSM-5 molecular sieve synthesized by template with certain degree of polycondensation does not decrease significantly.
