Abstract
In this work, NiWO4 nanoparticles were prepared by a novel simple method and loading on the mesoporous TiO2 whiskers (TiO2(w)) carrier as the precursor of NiWS. In addition, the NiWS-TiO2(w) catalysts showing high hydrodesulfurization (HDS) activity is described. The structure and chemical composition of the as-prepared samples were characterized by X-ray powder diffraction, X-ray photoelectron spectroscopy, temperature-programmed reduction, NH3-temperature programmed desorption and transmission electron microscopy, respectively. Results indicate that smaller crystallite size and better dispersion of active NiWO4 particles could be achieved by using TiO2(w) as the support to disperse NiWO4 nanoparticles. TiO2(w) can also decrease the reduction temperature of Ni–W metal oxide and promote a highly sulfidation degree of Ni and W active sites. The obtained NiWS-TiO2(w) catalysts show much higher dibenzothiop HDS activity than the unsupported NiWS catalyst, and the sulphur content of desulfurated oil can reach 20 ppm at the mild condition of 260 °C and 2 Mpa.
