SELECTIVE HYDROGENATION OF BUTADIENE-RICH C4 HYDROCARBON FRACTION IN LIQUID PHASE OF ACETYLENIC COMPOUND

摘要

Process of selective hydrogenation of a fraction rich in butadiene in contact with a palladium catalyst supports, characterizes in that one opere in mixture with a hydrocarbon, and an amine. / p & & p & the c fraction rich in butadiene 1 and the liquid hydrocarbon containing the amine 6 pass through the reactor 2. The product obtained is fractionated 13. The section c is collected in the vapour phase 15 and the liquid phase recycled 16.
