PROCESS FOR THE SELECTIVE HYDROGENATION IN THE PRESENCE OF SOLVENTS OF ACETYLENIC COMPOUNDS IN A C4-HYDROCARBON FRACTION COMPRISING BUTADIENE

摘要

A C4 cut of high butadiene content is selectively hydrogenated in contact with a supported palladium catalyst, the operation being performed in admixture with a hydrocarbon and an amine. The C4 cut of high butadiene content (1) and liquid hydrocarbon containing the amine (6) pass through reactor (2). The resultant product is fractionated (13). The C4 cut is recovered in the vapor phase (15) and the liquid phase recycled (16).
