Abstract
The present invention provides (i) a method and system for stabilizing the performance of amine-containing CO2 adsorbents using wet feed gas and/or wet purge gas and (ii) a method for regeneration of deactivated amine-containing CO2 adsorbents via hydrolysis of the urea groups formed during deactivation.
Claims5
A method of stabilizing an amine-containing CO2 adsorbent over multiple adsorption-desorption cycles comprising contacting said amine-containing CO2 adsorbent with one or more humid gas streams to stabilize the adsorbent, wherein the method comprises an adsorption step of contacting said amine-containing CO2 adsorbent with said one or more humid gas streams, and subsequently a desorption step of contacting said amine-containing CO2 adsorbent with said one or more humid gas streams or a dry gas stream, wherein said contacting steps are repeated during said multiple adsorption-desorption cycles of said system for removal of CO2.
