ABSTRACT:
An alkylation catalyst comprises from 50 to 70 wt % of hydrogen type ZSM-SM-11 co-crystaline zeolite containing rare earth element and the rest amount of porous inorganic oxide matrix material. The zeolite has particular chemical composition and X-ray diffraction lines. 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.
