    摘要: The invention pertains to a process for reducing the sulfur content of a hydrocarbon feedstock to a value of less than 200 ppm, preferably less than 50 ppm, which comprises subjecting a catalyst comprising a Group VIB metal component, a Group VIII metal component, and an organic additive on a carrier to a sulfidation step, and contacting a feedstock with a 95% boiling point of 450° C. or less and a sulfur content of 500 ppm or less with the sulfided catalyst under conditions of elevated temperature and pressure to form a product with a sulfur content of less than 200 ppm. The organic additive preferably is at least one compound selected from the group of compounds comprising at least two hydroxyl groups and 2-10 carbon atoms, and the (poly)ethers of these compounds.

    摘要: The present invention pertains to a process for sulfiding a catalyst composition comprising at least one hydrogenation metal component of Group VI and/or Group VIII of the Periodic Table, and an organic additive wherein the catalyst composition is first contacted with an organic liquid, followed by the catalyst being contacted with hydrogen and a sulfur-containing compound in the gaseous phase, wherein less than about 40%, preferably less than about 35%, more preferably less than about 25%, most preferably less than about 15%, of the sulfur present in the sulfided catalyst is added with the organic liquid. The process of the present invention makes it possible to use additive-containing catalysts without loss of activity in units which cannot effect gas phase start-up or are required to carry out a pressure test. The organic liquid may be a hydrocarbon with a boiling range of about 150-500° C., preferably gasoline, white spirit, diesel, gas oil, mineral lube oil, or white oil. The step of contacting the catalyst with hydrogen and a sulfur-containing compound may take place in one step at a temperature of about 150-450° C. It may also take place in two steps, with the first step being performed at a temperature which is lower than that of the second step, with the first step being carried out at a temperature of about 100-250° C. and the second step at a temperature of about 150-450° C.

    摘要: The present invention pertains to a process for preparing a catalyst composition wherein at least one Group VIII non-noble metal component and at least two Group VIB metal components are combined and reacted in the presence of a protic liquid, after which the resulting composition is isolated and dried, the total of the Group VIII and Group VIB metal components, calculated as oxides, making up at least about 70 wt. % of the catalyst composition, calculated on dry weight. An organic oxygen-containing additive is added prior to, during, or subsequent to the combining and reacting of the metal components in such an amount that the molar ratio of the total amount of additive added to the total amount of Group VIII and Group VIB metal components is at least about 0.01. The invention also pertains to additive-containing catalysts obtained by this process, and to their use in hydroprocessing.
