Abstract:
1. A process for the catalytic dewaxing of a hydrocarbon oil feed obtained by the vacuum distillation of the residue of an atmospheric distillation of a crude petroleum feedstock, wherein said hydrocarbon oil feed has a boiling range between 300° C. and 620° C. includes waxy molecules and more than 1000 ppmw of sulphur or sulphur containing compounds and said hydrocarbon oil feed has not been subjected to a hydrotreating step to reduce sulfur and nitrogen content, by contacting said hydrocarbon oil feed under catalytic dewaxing conditions with a catalyst composition comprising a Group VIII metal hydrogenation component selected from the group consisting of platinum palladium and nickel, dealuminated aluminosilicate zeolite crystallites and a low acidity refractory oxide binder material which is essentially free of alumina.
