NOVELTY - Gas component is selectively removed from gas mixture by providing temperature swing adsorption gas separation unit having adsorbent contactor(s) including parallel open flow channels having adsorbent material with selectivity for target gas component, passing gas mixture through flow channels to adsorb target gas component and heating adsorbent contactor(s) with heat transfer fluid to temperature that desorbs target gas component. A thermal wave (1071, 1073, 1075, 1077) is generated in the adsorbent contactor during desorption which creates thermal wave temperature gradient.    USE - Method of selectively removing gas component from gas mixture (claimed) for production of fuels, chemicals or petrochemicals.    ADVANTAGE - The method does not dilute desorbed materials into heating medium, has short cycle time, continuous flow of products that do not upset downstream processing equipment, is heat integrated in a way that majority of energy is recaptured and reused, and enables multicomponent separation of different species in feedstream with single adsorbent component contactor.    DETAILED DESCRIPTION - Gas component is selectively removed from gas mixture by providing temperature swing adsorption gas separation unit having adsorbent contactor(s) at initial temperature including parallel open flow channels with channel surface comprising adsorbent material having selectivity for target gas component over product gas component of greater than 1, passing gas mixture through fraction of flow channels to adsorb portion of target gas component and produce product gas stream having low mol% of target gas component, collecting product gas stream, heating adsorbent contactor(s) with heat transfer fluid to a temperature that desorbs fraction of target gas component from adsorbent material to produce waste gas stream having high mol% concentration of target gas component, collecting waste gas stream and cooling adsorbent contactor(s) to initial temperature. A thermal wave (1071, 1073, 1075, 1077) is generated in the adsorbent contactor during desorption which create a thermal wave temperature gradient that moves along the length of adsorbent contactor(s) having heat transfer delta-temperature of 0-50 degrees C which is a ratio of heat rate requirement and heat transfer coefficient.
