摘要
Abstract
Using large pore γ-Al2O3 prepared by acid precipitation, the Ni2P(25%)/γ-Al2O3 catalyst was prepared as the support by the impregnation method. The test results of XRD, BET and mercury porosimetry show that the large pore γ-Al2O3 has preferable surface area and pore structure. After in-situ reduction,the effects of preparation conditions and reaction conditions on dehydrocracking activitγ of the catalyst were studied in a fixed-bed down-flow reactor with the diesel as the material. The results show that desulfurization degree of 98. 2% would be attained under the optimum condition as follows: sγnthesis temperature of 80 ℃ , pH of 8, reaction temperature of 360 ℃ , reaction pressure of 4. 0 Mpa, liquid hourly space velocity of 1. 0 h-1 and volume ratio of hydrogen to cγclohexane of 500 : 1.关键词
