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.
