Hydrogenation and hydrocracking catalysts were designed and synthesized based on findings from catalyst characterization and model reactions. Two types of the synthesized catalysts were then tested using two stage upgrading of unconventional feedstocks. The causes of catalysts deactivation were studied in order to prepare a practical catalyst with a long life.
Two kinds of catalysts, designed and prepared based on fundamental research, showed superior catalytic activities in the first-stage and second-stage upgrading of unconventional middle and heavy distillates, resulting in considerable improvements in overall activity (hydrogenation, HDN, HDS and hydrocracking) and initial deactivation of two stage upgrading.
