Abstract
A process for the treatment of a feed comprising at least hydrocarbons containing at least 3 to 10 carbon atoms per molecule, including acetylenic and diolefinic hydrocarbons, comprises passing the feed into a distillation zone associated with a selective hydrogenation reaction zone comprising at least one catalytic hydrogenation bed which is internal to or external of the distillation zone, in which hydrogenation of at least a portion of the acetylenic and diolefinic hydrocarbons contained in the feed is carried out in the presence of a gas stream rich in hydrogen. The process is particularly suitable for the treatment of products from catalytic cracking.
