磷镍物质的量比对溶剂热法制备的磷化镍催化剂加氢脱硫性能的影响
Effect of P/Ni ratio on the structure and hydrodesulfurization performance of nickel phosphide catalyst prepared by the solvothermal method
摘要
Abstract
A series of MCM-41-supported Nix P catalysts was prepared by the solvothermal method using low-price triphenylphosphine as phosphorus material and tri-n-octylamine as coordinating liquid reaction system. They were characterized with X-ray diffraction, N2 sorption, CO sorption, X-ray photoelectron spectroscopy and transmission electron microscopy techniques. The effects of initial P/Ni molar ratio on their structures and hydrodesulfurization performances were investigated in a lab-scale continuous flow fixed-bed reactor by feeding 1% of dibenzothiophene ( DBT) in decahydronaphthalene. It was shown that Ni12 P5 was primarily formed with a small amount of Ni2 P at the initial P/Ni molar ratio of 0. 5. When the initial P/Ni molar ratio was higher than 0. 5, pure Ni2 P phase was generated, and its crystal size decreased, and thus, its dispersion increased with the increase of initial P/Ni molar ratio. At 613 K, 3. 0 MPa, H2/oil ratio of 500 (volume ratio), and weight hourly space velocity of 2. 0 h-1 , the DBT conversion nearly reached 100% on both the Ni-P(6)/MCM-41 and the Ni-P(10)/MCM-41 samples.关键词
