The invention relates to equipment for pretreatment of catalysts and/or catalytic testing that makes it possible to establish the material balance of a chemical reaction in the presence of very small amounts of solid catalyst under operating conditions of industrial use.

A method for separating at least a benzothiophene compound from a hydrocarbon mixture is disclosed. The method includes contacting the mixture of a fraction obtained therefrom with a reagent including an acceptor complexing agent &pgr;, to obtain a donor-acceptor complex between the acceptor complexing agent and the benzothiophene compound; and separating the complex from the mixture, or from the fraction, to obtain a fraction depleted or purified in the benzothiophene compound.

This invention relates to a hydrorefining catalyst containing ruthenium sulphide and cobalt and/or nickel sulphide on a refractory oxides support. These catalysts are only very slightly inhibited by polyaromatic compounds or hydrogen sulphide.

This invention relates to a method of hydrotreating hydrocarbon-based charges by using a catalyst that comprises V.sub.2 S.sub.3 prepared in situ in the reaction zone or V.sub.2 S.sub.3 prepared outside this zone but treated in this zone by a sulphurating agent. The hydrotreating method according to the invention can be used to treat hydrocarbon-based charges such as gasoline, gasoil, refinery residues and heavy crude oils, thus allowing the elimination of impurities such as nitrogen, sulphur and metals. The method can also be used to hydrogenize the olefins and the aromatics and possibly lead to rupture of the carbon-carbon bonds.
