Title:
HYDROGENATION METAL-REMOVING CATALYST FOR HYDROCARBON OIL AND HYDROGENATION METAL-REMOVING PROCESS FOR HYDROCARBON OIL THEREBY
Document Type and Number:
Japanese Patent JP3846965
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a hydrogenation metal-removing catalyst for hydrocarbon oils and a hydrogenation metal-removing process for hydrocarbon oils preventing the catalyst from clogging and rapid rise of pressure difference by maintaining spaces among the catalysts, and being capable of long-period continuous operation in hydrogenation metal-removing process for heavy gravity oils.
SOLUTION: The hydrogenation metal removal catalyst comprises a carrier and catalyst components 3 supported by the carrier wherein a part of the catalyst surface, preferably 30-90% catalyst surface, consisting of an inert material having no metal removal capability substantially, has a covering layer 2 rendering reaction fluid not to penetrate through substantially. It is preferable that specific surface area of the covering layer 2 is 10m2/g or less and the inert material forming the covering layer 2 is made of glass, inert ceramic, or metal inert under the reaction condition. It is suitable for a fixed-bed filling catalyst.
