不同金属含量Ni-W催化剂的煤焦油加氢脱硫脱氮性能研究
Hydrodenitrogenation and hydrodesulfurization of coal tar on Ni-W catalysts with different metal loadings
摘要
Abstract
The γ-Al2 O3 supported Ni-W catalysts with different metal contents for the hydroprocessing of low and middle-temperature coal tar were prepared and characterized by the X-ray diffractogram ( XRD ) , X-ray photoelectron spectroscopy ( XPS) , temperature programmed desorption of NH3( NH3-TPD) , N2 adsorption and high resolution transmission electron microscopy ( HRTEM ) . The hydrodenitrogenation ( HDN ) and hydrodesulfurization ( HDS) performances of the catalysts were evaluated by using low and middle temperature coal tar. The results show that the sulfidation degree of the catalysts increases with increasing metal content within a certain range, while the amount of total acid that mainly consists of intermediate acid decreases. The HDN activity of the catalysts with Ni/W atomic ratio of 0 . 786 increases initially and reaches an optimum value at 24% WO3 , and then decreases, while the HDS activity increases gradually.关键词
