Abstract
A process for the selective hydrogenation of a fraction of hydrocarbons containing 2 to 20 carbon atoms and comprising monounsaturated olefinic hydrocarbons and/or aromatic compounds and at least one polyunsaturated hydrocarbon from the group formed by acetylenic compounds and dienes, in which the hydrocarbon fraction, which is at least partially in the liquid phase, circulates with hydrogen in a given direction in a reactor containing at least one fixed bed of a hydrogenation catalyst in the form of a divided solid, characterized in that said reactor is provided with at least one inlet conduit for a fluid mixture comprising said hydrocarbon fraction and hydrogen and at least one outlet conduit for the hydrogenated hydrocarbon fraction, and in that it comprises at least one static mixer upstream of said outlet for the hydrogenated hydrocarbon fraction.
