ABSTRACT:
A method and operating technique for treating diene-containing aliphatic streams by introducing the light hydrocarbon stream at a top portion of a vertical stripping tower having an upper catalytic contact zone containing a bed of solid hydrogenation catalyst particles and a lower contact zone, and introducing a light gas stream containing hydrogen at a lower portion of said stripping tower. Selective hydrogenation is effected by flowing the light hydrocarbon stream and light gas stream countercurrently in contact with the solid hydrogenation catalyst particles under hydrogenation and stripping conditions, thereby converting said diene to mono-alkene in the upper contact zone.
