【Abstract】 The ZSM-5 zeolite sieve is synthesized using ammonia as templating agent. The influence of synthetic temperature and crystallizing time on the synthesis of the zeolite are studied .It is found that ZSM-5 zeolite sieve is synthesized using ammonia as templating agent at temperature ranging from 142℃ to 177℃.The lower the synthetic temperature, the longer the synthetic time .The structures of ZSM-5 zeolites synthesized using ammonia are characterized by the method of XRD, comparing with the structure of ZSM-5 zeolite synthesized using n-propyl amine.更多还原
