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,

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.

A thin film-forming method of forming a given thin film pattern on a surface of a substrate comprising the steps of: forming, on the surface of the substrate on which a thin film is formed, a mask with an opening to define a thin film-forming area having a pattern corresponding to the pattern of the thin film, producing an atmosphere containing pre-treating liquid microparticles produced by micronizing a pre-treating liquid so as to have at least the smaller diameters than the minimum distance of the mask pattern, positioning the substrate onto the atmosphere containing the pre-treating microparticles and thereby sticking the microparticles on the thin film-forming area, and forming a thin film from a solution on the thin film-forming area of the substrate which is wet with the pre-treating liquid. 22. A thin film-forming method as defined in claim 21, wherein the thin film is formed from a plating liquid on the surface of the substrate. 23. A thin film-forming method comprising the steps of: exposing a substrate on which a thin film is formed to an atmosphere containing microparticles produced by micronizing a pre-treating liquid and thereby sticking the microparticles on a thin film-forming area on the substrate, and forming a thin film from a solution on the thin film-forming area of the substrate on which the microparticles are stuck.
