A temperature swing adsorption process for removing a target component from a gaseous mixture containing at least one side component besides the target component, said process being carried out in at least one reactor performing the following steps: an adsorption step (a), wherein an input stream of said gaseous mixture is contacted with a solid adsorbent selective for said target component, producing a first waste stream depleted of the target component; a heating step (b) for regeneration of the loaded adsorbent providing a first output stream containing the target component; a cooling step (c) of the regenerated adsorbent, said process also comprising: i) a preliminary heating step (a) before said heating step (b), wherein a gaseous product containing said at least one side component is released from the adsorbent; ii) recycle of said gaseous product to a further adsorption step (a).

Temperature-swing adsorption process

A temperature swing adsorption (TSA) process for removing a target component from a gaseous mixture, where the process is carried out in a plurality of reactors. Each reactor performs the following steps: an adsorption step wherein an input stream of said gaseous mixture is contacted with a solid adsorbent selective for said target component, producing a first waste stream depleted of the target component; a heating step for regeneration of the loaded adsorbent providing a first output stream containing the target component; and a cooling step of the regenerated adsorbent.
