The invention relates to a process for removing acetylenes and 1,2-butadiene from hydrocarbon flows used as raw materials in chemical industry. According to the invention, the process consists in feeding hydrogen and C4 hydrocarbon flow comprising 1,2-butadiene and acetylenes, into a reactor with distillation column, containing a hydrogenation catalyst bed, there taking place simultaneously the hydrocarbon flow contacting with the hydrogen in the presence of the hydrogenation catalyst and the fractioned distillation of the reaction mixture in order to remove heavier fractions and a head fraction substantially comprising all C4 compounds having a reduced acetylene and 1,2-butadiene content. |
