    摘要: The invention features a method for treating a supported catalyst with a sulphur compound based active phase and a mercury compound contaminated mineral support. This method consists in implementing the following steps: the said catalyst is contacted with a basic aqueous solution of at least one sulphide selected among alkaline metal sulphides, alkaline-earth metal sulphides or ammonium sulphide; then the catalyst is separated from the basic aqueous solution. At the end of this process, the treated catalyst shows the same characteristics as before its contamination by mercury.

    摘要: A catalyst for isomerizing a hydrocarbon cut of high n-paraffin content is disclosed. The catalyst is obtained by controlled oxychlorination of a solid containing at least one group VIII metal supported on an acid mordenite, said mordenite having a sodium content lower than 0.2% by weight, adsorbing molecules of a kinetic diameter larger than about 6.6 Angstroms, having a mesh volume, V, of the elementary mesh from 2.73 to 2.78 nm.sup.3 and a benzene adsorption capacity higher than 5% by weight, said oxychlorination being conducted at a temperature of about 200.degree.-500.degree. C. by means of a gas mixture containing oxygen, water, chlorine or at least one chlorinated compound used in a total amount from 0.5 to 10% by weight of chlorine, in proportion to the mordenite weight. The catalyst may further contain a matrix, the mordenite amount being at least 40% by weight of the total amount of mordenite and matrix.
