Title
(EN) TWO STAGE PROCESS FOR HYDRODESULFURIZING DISTILLATES USING BULK MULTIMETALLIC CATALYST
(FR) PROCEDE A DEUX ETAGES METTANT EN OEUVRE UN CATALYSEUR MULTIMETALLIQUE EN VRAC POUR HYDRODESULFURER DES DISTILLATS
Abstract
(EN)
A two stage hydrodesulfurizing process for producing low sulfur distillates. A distillate boiling range feedstock containing in excess of about 3,000 wppm sulfur is hydrodesulfurized in a first hydrodesulfurizing stage containing one or more reaction zones in the presence of hydrogen and a hydrodesulfurizing catalyst. The liquid product stream thereof is passed to a first separation stage wherein a vapor phase product stream and a liquid product stream are produced. The liquid product stream, which has a substantially lower sulfur and nitrogen content than the original feedstream is passed to a second hydrodesulfurizing stage also containing one or more reaction zones where it is reacted in the presence of hydrogen and a second hydrodesulfurizing catalyst at hydrodesulfurizing conditions. The catalyst in any one or more reaction zones is a bulk multimetallic catalyst comprised of at least one Group VIII non-noble metal and at least two Group VIB metals.
(FR)
L'invention concerne un procédé d'hydrodésulfuration à deux étages destiné à produire des distillats à basse teneur en soufre. Une charge d'alimentation à plage d'ébullition du distillat contenant en excès environ 3.000 mg/l en poids de soufre est hydrodésulfurée dans un premier étage d'hydrodésulfuration comprenant une ou plusieurs zones de réaction, en présence d'hydrogène et d'un catalyseur d'hydrodésulfuration. Le débit diluat liquide résultant est soumis à une première étape de séparation pour obtenir un débit diluat en phase vapeur et un débit diluat liquide. Le débit diluat liquide, qui présente une teneur en soufre et en azote sensiblement inférieure à celle de la charge d'alimentation initiale, est placé dans un deuxième étage d'hydrodésulfuration comprenant également une ou plusieurs zones de réaction et soumis à une réaction en présence d'hydrogène et d'un deuxième catalyseur d'hydrodésulfuration, dans des conditions d'hydrodésulfuration. Le catalyseur, quelle que soit la zone (ou les zones) dans laquelle il est mis en oeuvre, est un catalyseur multimétallique en vrac constitué d'au moins un métal non noble du Groupe VIII et d'au moins deux métaux du Groupe VIB.
