摘要

"PROCESS FOR REMOVING ACETHYLENE AND METHOD PROPADIENE FROM A C ~ 3 ~ AND HIGHER CARBY BAND HYDROCARBON, AND PROCESS TO REMOVE ACETHYLENE AND PROPADIUM FROM A RICH FLOW". A process for the selective hydrogenation of methylene acetylene and propadiene (MAPD) in a propylene rich stream (101) is disclosed in which selective hydrogenation is performed in steps (a) first in a single pass fixed bed reactor (20). or 30) and then (b) in a distillation column reactor (40) containing a supported PdO hydrogenation catalyst (41) which serves as a component of a distillation structure. Conversion and selectivity for propylene are improved by using the single pass fixed bed reactor alone.
