A waxy hydrocarbon feed is catalytically dewaxed with a catalyst that has been selectively activated. The selective activation of the catalyst involves contacting the dewaxing catalyst with a feed mixture containing waxy hydrocarbon and at least one oxygenate. The process results in improved catalyst performance resulting in improved yield of isomerate at equivalent pour.
L'invention concerne une alimentation d'hydrocarbures cireux catalytiquement débarrassés des cires à l'aide d'un catalyseur qui a été sélectivement activé. L'activation sélective du catalyseur implique la mise en contact du catalyseur de déparaffinage avec un mélange d'alimentation contenant un hydrocarbure cireux et au moins un composé oxygéné. Le procédé permet d'obtenir une performance améliorée du catalyseur entraînant un rendement amélioré d'isomérat pour une coulée équivalente.
