Abstract: Processes and systems for the capture of CO2 from a CO2-containing gas stream are provided. The CO2-containing gas stream is passed to a membrane contactor absorber wherein the CO2-containing gas contacts or passes a first side of a membrane element while a CO2 selective solvent with a viscosity between 0.2 and 7 cP contacts, passes or flows on second side of the membrane, opposed to the first side. The CO2 permeates through the hollow fiber membrane pores and is chemically absorbed into the solvent.

Abstract: Processes and systems for the energy efficient capture of CO2 from a flue gas stream such as produced or resulting from power plant operation, are provided. The processes and systems integrate the use of high CO2/N2 selectivity membranes and high CO2 flux membranes, to capture CO2. Useful membranes can desirably be graphene oxide-based membranes.

Abstract: Methods and systems or devices for synthesis of dimethyl ether (DME) from carbon dioxide and hydrogen are provided. A high surface area hollow fiber catalytic membrane reactor such as with hollow fibers coated with a water permeable membrane material is used. The reactor also contains a bi-functional methanol synthesis component and dehydration catalyst component such that the two-step reaction takes place on the catalyst surface. Produced water permeates through the membrane, exiting the reactor immediately after it is formed. Unreacted reactants and products flow to the reactor exit.

Abstract: An apparatus for gas separation a composite gas separation membrane having a gas separation layer disposed on a surface of a porous support. The gas separation layer has a plurality of gas permeable inorganic nano-particles embedded in a dense polymer forming substantially only discrete gas transport channels through the dense polymer layer, wherein direct fluid communication is provided from a feed side of the composite gas separator membrane to the porous support. Preferably, the inorganic nano-particles are porous molecular sieve particles, such as SAPO-34, ALPO-18, and Zeolite Y nano-particles.
