制备方法及载体类型对Ni2 P／TiO2催化剂加氢脱硫性能的影响
Effect of preparation method and support type on hydrodesulfurization performance of Ni2 P/TiO2 catalyst
摘要
Abstract
Nickel phosphide catalysts, supported on whiskers and anatase TiO2 , were prepared by temperature programmed reduction method and os lvothermal method, respetc ively.The catalysts were characterized by X-ray diffraction ( XRD ) , N2-adsorption specific us rface aream easurements ( BET ) , N2 adsorption-desorption, CO adsorption, Xr-ayp hotoelectron spectroscopy ( XPS) and scna ning lee ctronm icrocs opy ( TEM) .The effects of rp eparation meht od and support type on c atalyst ca tivity for dibenzoht iophene ( DBT ) hydrodesuluf rization ( HDS) were stdu ied. The result soh wed that the structurse of the TiO2 support remained unchangde , and the of rmation of TiPO4 was suppressed in solvothermal method process, contributing to higher catalytic activity of Ni2 P/TiO2 catalysts for HDS than the catalysts obtained by conventional TPR method.Compared with the catalysts supported on anatase TiO2 , the catalysts supported on whiskers TiO2 displayed excellent surface properties, producing more Ni2 P crystal particles with smaller size and better dispersion, and therefore possessed higher HDS activity.The HDS activity of the catalyst supported on whiskers TiO2 and made by solvothermal method was found to be the best one among the tested catalysts.The conversion of dibenzothiophene HDS was 98.2%under the selected reaction conditions of 340 ℃, 3.0 MPa, H2/oil ratio of 500 (volume ratio), and WHSV of 2 .0 h-1 .关键词
