摘要： The invention involves a method for treatment of a charge comprising at least hydrocarbons containing at least three carbon atoms per molecule, including acetylenic and diolefinic hydrocarbons. The method entails the passage of the charge through a distillation zone linked to a hydrogenation reaction zone comprising at least one catalytic hydrogenation bed inside or outside the distillation zone, in which at least a portion of the acetylenic and diolefinic hydrocarbons contained in the charge is hydrogenated in the presence of a hydrogen-rich gas flow. This method is particularly relevant to the treatment of catalytic cracking products.

摘要： The invention relates to a method for producing low-sulphur petrol comprising at least one sulphur compound transformation step consisting of the alkylation or adsorption of the sulphur compounds and/or in increasing the weight of the light sulphur compounds; at least one step involving treatment in the presence of an acid catalyst; and at least one step consisting in desulphurising at least one part of the petrol. According to the invention, the method can also optionally comprise at least one step involving the selective hydrogenation of diolefins and, optionally, at least one fractionation of the petrol obtained into at least two fractions: light petrol and heavy petrol.

摘要： The invention relates to a method for producing low-sulphur petrol from an initial petrol containing sulphur compounds comprising the following steps: a) the selective hydrogenation of the non-aromatic polyunsaturated compounds present in the initial petrol; b) increasing the molecular weight of the light sulphur products that were initially present in the petrol at the beginning of step b); c) the alkylation of at least part of the sulpur compounds present in the product resulting from step b); d) the fractionation of the petrol resulting from step c) into at least two fractions, one of said fractions being practically free of sulphur compounds and the other containing a larger proportion of sulphur compounds (heavy petrol); e) the catalytic treatment of the heavy petrol to transform the sulphur compounds in conditions that allow the, at least partial, decomposition or hydrogenation of said sulphur compounds.
