Process for the catalytic dewaxing of a hydrocarbon oil feed including waxy molecules and more than 500 ppmw of sulphur or sulphur containing compounds by contacting the oil feed under catalytic dewaxing conditions with a catalyst composition comprising at least a hydrogenation component, dealuminated aluminosilicate zeolite crystallites and a low acidity refractory oxide binder material which is essentially free of alumina.
Ce procédé de déparaffinage catalytique d'une charge d'huile hydrocarbure, renfermant des molécules de paraffine et plus de 500 mg/L en poids de soufre ou de composés contenant du soufre, consiste à mettre en contact la charge d'huile, dans des conditions de déparaffinage catalytique, avec une composition catalytique comprenant au moins un composant d'hydrogénation, des cristallites de zéolithe d'aluminosilicate désaluminisée et un liant à base d'oxyde réfractaire de faible acidité et quasiment exempt d'alumine.
