Ni2P／SBA-15催化剂的制备及加氢脱氮性能的研究
Preparation of Ni2 P/SBA-15 catalyst and research of its hydrodenitrogenation performance
摘要
Abstract
The supported nickel phosphide catalysts were prepared by incipient wetness impregna‐tion and in situ H2 reduction method .The effects of the different P/Ni ratio ,reduction temperature , and active component mass fraction on the performance of hydrodenitrogenation were examined .The samples were characterized by N2 adsorption‐desorption ,X‐ray diffraction (XRD) ,and temperature‐programmed desorption of ammonia ,and the effects of different temperature on the properties of cata‐lyst hydrodenitrogenation (HDN ) w ere evaluated on a continuous‐flow fixed‐bed reactor by using quinoline as the model molecules .T he results show that w hen the nickel phosphorus ratio is 1 ,nickel phosphide mass fraction is 30% ,and the reduction temperature is 650 ℃ ,its catalytic activity is best . At a reaction temperature of 360 ℃ ,pressure of 3 MPa ,hydrogen/oil volume ratio of 500 ,and liquid hourly space velocity of 2 h-1 ,the HDN conversion of quinoline can reach 85 .6% .关键词
