The invention pertains to a hydroprocessing catalyst comprising a Group VIB hydrogenation metal component, a non-noble Group VIII hydrogenation metal component, an alkali metal component, and silica. The catalyst has a specific surface area, total pore volume and pore size distribution. The invention also pertains to the use of this catalyst in hydroprocessing of heavy hydrocarbon feedstocks, e.g, in an ebullated bed process.

Hydroprocessing catalyst and use thereof

The invention pertains to a catalyst at least comprising a hydrogenation metal component and a swelling synthetic clay consisting of elemental clay platelets, with the average diameter of the clay platelets not exceeding 1 micron and the average degree of stacking of the clay platelets not exceeding 20 platelets per stack. The catalyst is especially suitable for the hydroprocessing of hydrocarbon feeds, the term &ldquo;hydroprocessing&rdquo; encompassing all processes in which a hydrocarbon feed is treated with hydrogen. The clays which are suitable for use in the catalyst according to the invention may be prepared as described in Netherlands patent application No. 9401433.

Catalyst comprising at least a hydrogenation metal component and a synthetic clay and a process of using

The present invention relates to a process for preparing a hydroprocessing catalyst comprising the steps of subjecting a spent hydroprocessing catalyst comprising carbonaceous and sulphurous deposits to a thermal treatment to remove at least part of said deposits, grinding the thus obtained spent catalyst, mixing the ground hydroprocessing catalyst with at least one additive, and shaping the mixture of additive and ground hydroprocessing catalyst to form particles of a new hydroprocessing catalyst, with the spent hydroprocessing catalyst being subjected to a high-temperature calcination step carried out at a temperature in the range of 550-1000.degree. C. for a period sufficient to increase the MPD of the spent catalyst by at least 0.5 nm. The process according to the invention is particularly suitable for preparing ebullated bed catalysts from spent hydroprocessing catalysts.
