Title: Selective hydrogenation of acetylenes and dienes in a hydrocarbon stream.
Inventor: ABRAHAM P GELBEIN
IPC: C07C5/09
Filed: 2004-03-04
Abstract: Acetylenes and dienes in a stream containing hydrogen, methane, C2-C6 olefins and paraffins, C2-C6 acetylenes and dienes, benzene, toluene, xylenes, and other C6+ components are hydrogenated in a downflow boiling point reactor wherein the heat of reaction is absorbed by the liquid in the reactor which produces a vapor.
