Abstract: A high activity catalyst is obtained by oxidizing and modifying the surface of zinc sulfide by hydrogen peroxide. An oxidation treatment is carried out in basic aqueous solution. The high activity photocatalyst is added to the basic aqueous solution in which hydrogen sulfide is dissolved to recover hydrogen and sulfur under low energy. Thus, the inexpensive high activity photocatalyst having a high catalytic activity and a long duration of life is realized and hydrogen gas is efficiently generated under little energy.

Abstract: A process for the production of a supported catalyst. The process comprises heating a slurry that comprises a catalyst support and at least one active catalytic ingredient precursor. Gas is introduced to the slurry at a sufficient pressure to reduce the at least one active catalytic ingredient precursor and deposit at least one active catalytic ingredient onto a surface of the catalyst support to form the supported catalyst. The supported catalyst has a large active catalytic surface area.

Abstract: Highly active supported catalyst compositions and methods for producing more active supported catalyst compositions are disclosed. Said methods comprise steps for applying an adhesive coating of a catalytically active exfoliated transition metal dichalcogenide and promoters to the surface of a support medium prior to filling the pores of the support medium with catalytically active metals and/or promoters. A new method for applying a surface coating to a support is also disclosed.

Abstract: 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 150-500null 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 150-450null 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 100-250null C. and the second step at a temperature of about 150-450null C.

Abstract: 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 150-500null 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 HSnullR1nullCOOR, 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.
