Abstract: An adsorption module and associated processes for conducting advanced separations processes such as sorption enhanced water-gas shift (SEWGS). The adsorption module contains at least one angled baffle to create at least two tapered adsorbent beds within the adsorption module. The taper is such that the adsorbent beds' cross-sections within the adsorption module decrease in the direction of feed flow, thereby taking advantage of increased product purity and process efficiency provided by tapered adsorption beds.

Abstract: In various aspects, methods are provided for hydrogen production while reducing and/or mitigating emissions during various refinery processes that produce syngas, such as power generation. Syngas can be effectively separated to generate high purity carbon dioxide and hydrogen streams, while reducing and/or minimizing the energy required for the separation, and without needing to reduce the temperature of the flue gas. In various aspects, the operating conditions, such as high temperature, mixed metal oxide adsorbents, and cycle variations, for a pressure swing adsorption reactor can be selected to minimize energy penalties while still effectively capturing the CO2 present in syngas.
