Abstract

The properties and compositions of feedstock have great impact on reaction performances in residue hydrotreating and hydrocracking. The deactivation of residue hydrotreating and hydrocracking catalysts are mainly due to the high content of sulfur and nitrogen in residue. The removal rate of sulfur and nitrogen is an important parameter for the stability and life of catalyst. The primary objective of the present work is to prepare highly efficient denitrification catalyst. According to the mechanism of nano self-assembly, a series of Mo-Ni nano self-assemble catalysts were prepared by the method of forward and reverse micelles. The results shown that refining catalysts with the Mo and Ni ratio of 6:1, the theory loading is 30%, the denitrification rate was 56.2%; While the Mo and Ni ratio of cracking catalyst is 6:1, the theory loading is 25%, the Mo-Ni nano self-assemble catalysts will reach the best performance at the denitrification rate of 58.3%. For further studies grading the high activity of hydrotreating catalyst SS-1 and hydrocracking catalyst SS-2 in a fixed bed microreactor to investigate the denitrification rate with different process by orthogonal experiments. The result shown that when pressure arrived 14MPa, LVSH is 0.2h-1, reaction temperature is 390°C, hydrogen/oil ratio 850:1 is the final investigation result, at this point HDN = 79.20%.
