Heavy arene lightening catalyst and the separating method of lightened product

A catalyst consists of VIII-metals 0.05-0.3 wt%, zeolite with MOR struture 20-59 wt%, zeolite with MFI structure 20-50 wt% and alumina 20-40 wt%. During the lightening process, heavy arene containingC9 is made to contact with the catalyst in the condition of 350-450 deg.C and 0.5-3.5 MPa to obtain lightened product, which is fractionated to obtain BTX as well as sym-trimethylbenzene, meta-trimethylbenzene, sym-tetramethylbenzene and other organic material.
