过渡金属磷化物制备与加氢脱硫性能研究进展

摘要

近年来油品重质化越来越严重，环保法规要求也日趋严格，为满足环境保护和人们的需求，对油品的加氢脱硫成为一项紧迫任务。综述了近年来过渡金属磷化物在复合载体和制备方法等方面的最新研究进展情况，其中具体介绍了程序升温还原法及低温热分解法，同时概述了过渡金属磷化物的加氢脱硫性能。%In recent years the cru d oil is becoming poorer and the regulations for environmental protection are more stringent. In order to meet the requirements of environmental protection, the hydrodesulfurization of oil is an urgent task. In this paper, the latest advances in the composite supports and preparation techniques of transition metal phosphides were reviewed, specially temperature-programmed reduction and low temperature thermal decomposition method. Meanwhile, the hydrodesulfurization properties of transition metal phosphides were summarized.
