Ni2P catalysts supported on SiO2, ZSM-5, Beta, and USY zeolites were prepared by temperature-programmed reduction (TPR) method, and characterized by N2 adsorption/desorption, CO uptake, NH3-TPD, TEM, X-ray diffraction (XRD), and extended X-ray absorption fine structure (EXAFS), and applied for the hydrocracking (HCK) of polycyclic aromatic hydrocarbons (PAHs). The catalytic activity was tested at 673 ~ 723 K and 3.0 MPa in a three-phase fixed bed reactor for HCK of naphthalene as a model feed or hydrotreated light cycle oil (LCO) as a real feedstock. For the HCK of naphthalene, the Ni2P/Beta exhibited best activity with a naphthalene conversion of 99%, and a BTX yield of 94.4%. In particular, the catalyst showed good and stable activity for LCO HCK with BTX yield over 80% which was attributed to the unique catalytic nature of moderate acidity and porosity of zeolite Beta combined with hydrogenation activity of well-dispersed Ni2P phase.. Overall, the Ni2P/Beta can be a potential hydrocracking catalyst for upgrading polycyclic aromatic hydrocarbons (PAHs) into BTX.Fig. 1. Schematic of naphthalene HCK over Ni2P catalyst.Fig. 2.
