BETA ZEOLITE CATALYST FOR PREPARATION OF MIXTURE OF BTEX (BENZENE, TOLUENE, ETHYLBENZENE, XYLENE) FROM POLY AROMATIC HYDROCARBONS AND PREPARATION METHOD THEREOF

摘要

The present invention relates to a beta zeolite catalyst for the preparation of a BTEX (benzene, toluene, ethylbenzene, xylene) mixture from polyaromatic hydrocarbons and a preparation method of the same. The beta zeolite catalyst of the present invention demonstrates the high conversion of polyaromatic hydrocarbons and the high BTEX production yield by containing the optimum contents of the group VIB metals and cocatalysts, so that it can be effectively used as a beta zeolite catalyst for the production of BTEX.
