Abstract

Abstract: DIJ hydroisodewaxing catalyst for diesel fuel was developed using zeolite-alumina support and W-Ni active components. The physical-chemical properties of the catalyst were characterized by XRD, FT-IR and BET techniques. The activity and stability of the catalyst were evaluated on a hydrogenation unit combined with a hydrofining catalyst, using Daqing coker gas oil and the mixture of coker gas oil/FCC LCO as feed respectively. Results showed that the yield of diesel fuel was more than 89.0% with sulfur content less than 50.0 ?g/g, its freezing point was lowered more than 14 ℃ and the loss of cetane number was less than 0.6 units, which indicated that DIJ catalyst possessed good activity and stability.

Key words: diesel oil, hydrodewaxing, catalyst
