摘　　要：介绍了过渡金属磷化物优异的加氢脱硫、加氢脱氮活性和稳定性,这已成为加氢领域的研究热点,有可能取代部分贵金属而成为新一代加氢处理催化剂。叙述了过渡金属磷化物的性质、结构、制备方法,在所有的过渡金属磷化物中,磷化镍活性最高。并总结了不同P/Ni配比、载体对磷化镍活性的影响,以及磷化镍在加氢脱氯方面的研究进展。认为金属磷酸盐的还原是传统的制备磷化物的方法,但过程涉及高温、成本高,不利于工业化大规模生产,改进磷化物的还原过程、降低能耗,成为研究的热点。Transition metal phosphides have excellent hydrodesulfurization, hydrodenitrification activity and stability. They have become a research hotspot in the field of hydrogenation, and may replace some precious metals and become a new generation of hydrotreating catalysts. The properties, structure and preparation methods of transition metal phosphides were reviewed. Among all the transition metal phosphides, nickel phosphide had the highest activity. The effects of different Ni:P and carriers on the activity of nickel phosphide were summarized. The research progress of nickel phosphide in hydrodechlorination was also summarized. It was pointed out in this paper that the reduction of metal phosphate is a traditional method of preparing phosphide, but the process involves high temperature and high cost, which is not conducive to large- scale industrial production. Improving the reduction process of phosphide and reducing energy consumption has become a research hotspot.
