Effects of Alcohol as Organic Auxiliary Chemical on Textural Property and Catalytic Performance of MCM-22 Zeolite

Hang Chunyan Li Jianwei Sun Xiaoyan Li Yingxia Chen Biaohua (State Key Laboratory of Chemical Resource Engineering,Beijing University of Chemical Technology,Beijing 100029,China)  
A series of MCM-22 zeolite samples were synthesized by dynamic hydrothermal crystallization method,taking alcohol as organic auxiliary chemical and hexamethyleneimine as template.The effects of alcohol on the textural property and acidity of MCM-22 zeolite catalyst were investigated based on the characterization of X-ray diffraction (XRD),ammonia temperature- programme desorption (NH_3-TPD),fourier transform infrared (FT-IR) and scanning electron microscopy (SEM).The results showed that the proper amount of alcohol could effectively adjust the textural property and acidity of MCM-22 zeolite.The crystallinity of MCM-22 synthesized with alcohol was slightly higher than those synthesized without alcohol.With the increasing of molar ratio of alcohol to SiO_2,the strength of weak acid decreased gradually while strong acid increased,total acid and Bronsted acid increased while Lewis acid decreased.And the lamellas of high crystallization could be seen from the SEM images and their sizes were smaller than those synthesized without alcohol.However,excessive alcohol introducing would lead to form ZSM-5 zeolite.It could be predicted that such adjustment of textural property would definitely influence the catalytic perform- ance of MCM-22 zeolite.Taking the alkylation of benzene with propylene to form cumene as a model reaction,the catalytic performance of MCM-22 zeolite synthesized was experimentally evaluated.The results showed that when the molar ratio of alcohol to SiO_2 was 0.5—1.0,significant increasing of initial activity of MCM-22 and cumene selectivity could be obtained.
