| 摘 要： | 由于丙烯衍生物需求量迅速增长，致使全球丙烯需求增长速率超过乙烯，近年来，人们一直在寻求新的丙烯增产的方法，采用分子筛作为催化剂，通过裂解C4及C4以上富烯烃原料来获取高收率的丙烯已引起国内外学者的高度关注，Rubinm等于1990年首先合成出MCM-22分子筛，由于其特有的酸性和独特的孔结构而被广泛用于各类化学反应中，迄今尚未见文献报道MCM-22分子筛在C4烯烃裂解反应中的催化性能研究，由于高硅铝比分子筛具有相对较高的热稳定性和水热稳定性，

| Abstract: | MCM-22 zeolite with a high SiO_2/Al_2O_3 ratio was synthesized in the hydrothermal system of Na_2O-SiO_2-Al_2O_3-(CH_2)_6NH and its catalytic performance in the C_4-olefins cracking reaction was investigated. It was found that MCM-22 showed an excellent catalytic performance on C_4-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 C_4 olefins indicates that the deactivation rate of HMCM-22 is lower than that of HZSM-5. |
