Abstract: MCM-22 zeolite with a high SiO2/Al2O3 ratio was synthesized in the hydrothermal system of Na2O-SiO2-Al2O3-(CH2)6NH and its catalytic performance in the C4-olefins cracking reaction was investigated. It was found that MCM-22 showed an excellent catalytic performance on C4-olefins cracking reaction to produce propylene. The results indicated that high temperature and high LHSV(liquid hourly space velocity) were favorable for the production of propylene with a high selectivity. Lifetime test of HMCM-22 and HZSM-5 for the cracking of C4 olefins indicates that the deactivation rate of HMCM-22 is lower than that of HZSM-5.

Key words: Catalytic cracking, MCM-22, C4-olefins, Propylene
