Process and device for selective hydrogenation by catalytic distillation including a reaction zone with an ascending cocurrent flow of liquid and gas

Abstract From the Canadian patent

he invention concerns a reactive distillation device comprising a distillation zone associated with a reaction zone which is at least partly inside the distillation zone and includes at least one catalytic bed in which the charge is converted in the presence of a catalyst and at least one gas stream including hydrogen. Any catalytic bed in the internal part of the said reaction zone is traversed by an ascending cocurrent flow of said gas stream and the liquid. The invention also concerns processes for the selective hydrogenation of light unsaturated hydrocarbons mainly olefins and benzene, contained in a mixture made up primarily of hydrocarbons with at least five carbon atoms per molecule …
