    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: A process for the sulfiding of a hydrodesulfurization catalyst for example in a distillation column reactor. The catalyst in the distillation column reactor is first dried using nitrogen and the reactor is filled with a sulfiding solvent and circulation begun. The reactor is heated to a temperature above the decomposition temperature of the sulfiding agent to be used and the sulfiding agent charged to the reactor. When sulfiding agent breakthrough is noted in the overheads the temperature is raised and held until sulfiding is complete.

    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 S-containing 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. The invention also pertains to the sulfided catalyst composition and its use in hydrotreating. Catalysts sulfided by the process according to the invention show a higher activity than the same catalysts which have not been sulfided. It is preferred to carry out the process according to the invention ex situ, where it solves the problem of difficult start-up and the formation of undesirable side products in the hydrotreating unit. The organic liquid may be a hydrocarbon with a boiling range of about 150-500° C., preferably white oil, gasoline, diesel, gas oil, or mineral lube oil. The S-containing organic additive preferably is a mercapto-compound, more preferably a mercaptocarboxylic acid represented by the general formula HS—R1—COOR, wherein R1 stands for a divalent hydrocarbon group with 1- about 10 carbon atoms and R stands for a hydrogen atom, an alkali metal, an alkaline earth metal, ammonium, or a linear or branched alkyl group having 1 to about 10 carbon atoms.

    摘要: For the presulphurization of catalysts based on metal oxides, intended especially for the hydrotreating of hydrocarbon feedstocks, at least one tertiary mercaptan (for example tert-dodecyl mercaptan) is employed as sulphurizing agent. This tertiary mercaptan can be employed alone or combined with another sulphur-donor compound. The presulphurization according to the invention may be carried out in situ or ex situ.

    摘要: The present invention aims at inhibiting a lowering in the modification ratio of a modified cation-exchange resin, in which part of the sulfonic acid groups have been modified with a thiol-containing amine compound and which is employed as a catalyst for producing bisphenol, during preservation. In the present invention, a modified cation-exchange resin is packed together with water into a container while regulating the surface area of the container to 0.5 m2 or less per liter of the resin and then the container is sealed up so that the resin is preserved in a state of being soaked in water.
