PROCESS FOR THE OXIDATIVE DEHYDROGENATION OF ETHANE

摘要

The invention relates to a process for the oxidative dehydrogenation of ethane to ethylene, comprising a reaction step which comprises subjecting a gas stream comprising ethane and air to ethane oxidative dehydrogenation conditions resulting in a gas stream comprising nitrogen, ethane and ethylene; a sorption step which comprises contacting the gas stream comprising nitrogen, ethane and ethylene resulting from the reaction step with a sorption agent which has an affinity for nitrogen which is lower than that for ethane which in turn is lower than that for ethylene, resulting in sorption of ethylene and optionally ethane by the sorption agent and in a gas stream comprising nitrogen and optionally ethane; and a desorption step which comprises desorbing sorbed ethylene and optionally ethane resulting in a gas stream comprising ethylene and optionally ethane.
