摘要
本文主要综述了Co、Ni在加氢精制催化剂中的助剂作用;加氢精制催化剂的发展历程;无Co、Ni助剂的加氢精制催化剂的发展历程,主要的活性组分包括单一过渡金属硫化物、贵金属硫化物及过渡金属的碳、氮、磷化合物;展望了来来无Co、Ni助剂加氢精制催化剂的发展趋势。
This paper summarized the research progress on hydrotreating catalysts of free Ni and Co promotion at home and abroad.There is a brief review of the history which includes the hydrotreating catalysts and free Co and Ni promotion catalysts.This paper also made analysis to the Single transition metal sulfides,transition metal carbides,nitrides and phosphides and Fe based catalysts,and made prospect to the development trend of this problem
