Removal of CO2, N2, or H2S from gas mixtures by swing adsorption with low mesoporosity adsorbent contactors

摘要

The present invention relates to the separation of one or more of CO, N, and HS gas components from a gas mixture containing at least a second gas using a swing adsorption process unit. The adsorbent contactors of the swing adsorption process unit are engineered structured adsorbent contactors having a plurality of flow channels wherein 20 volume percent or less of the open pore volume of the contactors is in the mesopore and macropore range.
