摘要：
The present invention provides a method for economical recovery of ethylene from ethylene-containing vent gas from a plant for production of ethylene oxide, wherein ethylene is separated from saturated hydrocarbons such as methane, ethane and oxygen and then recovered efficiently. In this method, the vent gas is made to contact with molecular sieve carbon to selectively adsorb ethylene without substantial adsorption of the oxygen contained in the vent gas, the ethylene then being desorbed and recovered.
