| Abstract: | A hydrodenitrogenation catalyst comprising molybdenum, nickel and phosphorus components supported on alumina was prepared. The effects of peptizing agents and calcination temperature on surface area and pore structure of the alumina support were investigated. The alumina support was obtained from bochmite having specific pore structure prepared by pH swing method and succeeded with shaping and calcination. The changes in physicochemical properties of the catalyst during the impregnation course were also observed. The activity and stability of hydrodenitrogenation were evaluated in a 100 ml reactor with a VGO having high nitrogen content as feedstock, and the result was satisfied. |
