Abstract
A process for the selective hydrogenation of the methyl acetylene and propadiene (MAPD) in a propylene rich stream is disclosed wherein the selective hydrogenation is carried out stepwise (a) first in a single pass fixed bed reactor and then (b) in a distillation column reactor containing a supported PdO hydrogenation catalyst which serves as a component of a distillation structure. Conversion and selectivity to propylene in improved over the use of the single pass fixed bed reactor alone.
