FIELD: chemistry.
SUBSTANCE: method of selective hydrogenation of acetylenes and dienes in the flow of the C5 hydrocarbons include: hydrogen supply and C5-olefin-containing stream containing the linear pentenes, dienes, acetylenes and cyclopentene, in the reaction system of catalytic distillation; at the same time in the reactor system of catalytic distillation: hydrogenation of acetylenes and dienes; and fractionation C5-olefin-containing stream; removing the head of the faction that contains linear pentenes; removing the side fractions containing cyclopentene; and extract cubic faction. Also the invention relates to method of conversion of linear pentenes in propylene and selective hydrogenation of acetylenes and dienes in a stream of C5 hydrocarbons.
EFFECT: lower costs.
