Abstract
A method for purification of ethylene-containing feedstreams from steam crackers or fluid catalytic crackers (FCC), wherein the feedstreams further comprises hydrogen, carbon monoxide, acetylenes, oxygen, nitric oxides, is disclosed. The method comprises contacting an ethylene-comprising gas stream with a Ru-based catalyst at reaction temperatures of at least 120°C. The process results in an ethylene-containing feedstream wherein the ethylene is essentially free of acetylenes, nitric oxides and oxygen. The purifying of the feedstream occurs with minimal loss of ethylene.
