A series of Y zeolites with different pore properties was prepared as a support for hydrocracking catalysts the production BTEX (benzene, toluene, ethyl-benzene, and xylene) from tetralin. Some important characterizations, including N2 adsorption–desorption, NH3-TPD, Py-IR, HRTEM, were applied to obtain catalysts. Meanwhile, tetralin performances those investigated on high-pressure fixed-bed mi...
