Publication date: February 2015 Source: Vacuum, Volume 112 Author(s): Limin Song , Shujuan Zhang , Xiaoqing Wu , Kai Wang Silica-supported NiCoP (NiCoP/SiO 2 ) catalysts were prepared by reducing nickel chloride (NiCl 2 ·6H 2 O) and cobalt chloride (CoCl 2 ·6H 2 O) with red phosphor (P) precursors. Physicochemical properties were determined by inductively coupled plasma spectroscopy, N 2 adsorption experiment, X-ray diffraction, transmission electron microscopy, Fourier transform infrared spectroscopy, and differential scanning calorimetry. Catalytic activities against the hydrodesulfurization of dibenzothiophene were evaluated in a fixed-bed reactor in flowing H 2 . The as-prepared NiCoP/SiO 2 catalyst exhibited high hydrodesulfurization activities and selectivity for indirect hydrodesulfurization (>90%).
