Title (EN) PROCESS FOR DEWAXING HEAVY AND LIGHT FRACTIONS OF LUBE BASE OIL WITH ZEOLITE AND SAPO CONTAINING CATALYSTS
(FR) PROCEDE DE DEPARAFFINAGE DE FRACTIONS LOURDES ET LEGERES D'HUILE DE BASE LUBRIFIANTE EN PRESENCE DE CATALYSEURS A ZEOLITE ET A SILICOALUMINOPHOSPHATE (SAPO)
Abstract: front page image
(EN)An integrated process is provided for preparing a dewaxed heavy lube base oil product and a dewaxed light lube base oil product from a waxy feedstock. The process includes separating the waxy feedstock into two or more fractions. A light fraction is upgraded to increase its VI, and dewaxed in an isomerization process using a wax isomerization catalyst such as SAPO-11, SAPO-31 or SAPO-41. A heavy fraction is upgraded to increase its VI, and dewaxed in the presence of a wax cracking catalyst such as ZSM-5.
(FR)L'invention porte sur un procédé intégré de préparation d'huile de base lubrifiante lourde et d'huile de base lubrifiante légère déparaffinées à partir d'une charge cireuse. Le procédé consiste à séparer cette charge en au moins deux fractions. On concentre une fraction légère pour augmenter son indice de viscosité puis on la déparaffine dans un processus d'isomérisation en présence d'un catalyseur d'isomérisation de la paraffine tel que SAPO-11, SAPO-31 ou SAPO-41. On concentre une fraction lourde pour en augmenter l'indice de viscosité et on la déparaffine en présence d'un catalyseur de craquage de la paraffine tel que ZSM-5.
