摘要： An alkylation catalyst comprises from 50 to 70 wt.% of hydrogen type ZSM-5/ZSM-11 co-crystalline zeolite containing rare earth element and the rest amount of porous inorganic oxide matrix material. The zoelite has particular chemical composition and X-ray diffraction line. This catalyst has higher activity, selectivity and stability in alkylation process than that of the prior art. With this catalyst the process for preparing ethyl benzene by alkylation of benzene with ethylene has higher ethylene conversion and ethyl benzene selectivity.

摘要： This invention concerns a zeolite containing rare earth elements and possessing cocrystallization structure of ZSM-5 and ZSM-11, wherein, weight rate of crystal phase structure portion of ZSM-5 and ZSM-11 is from 0.1 to 10. Chemical composition of the prototype zeolite synthesized under anhydrous state is as follows: 0.1-1.0 Na2O, 0.01-1.0 RE2O3, Al2O3. 20-300 SiO2. X-ray diffraction spectral lines of the zeolite Na-type are shown in table 1. The zeolite possesses good acidic hydrothermal stability and anti-impurities contamination ability, and can be used as catalyst in varied hydrocarbon conversion processes.
