Processes and systems for the capture of COfrom a CO-containing gas stream are provided. The CO-containing gas stream is passed to a membrane contactor absorber wherein the CO-containing gas contacts or passes a first side of a membrane element while a COselective 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 COpermeates through the hollow fiber membrane pores and is chemically absorbed into the solvent.

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.

Aspects of the invention are associated with the discovery of processes for converting methane (CH), present in a methane-containing feedstock that may be obtained from a variety of sources such as natural gas, to higher hydrocarbons (e.g., Chydrocarbons) such as gasoline, diesel fuel, or jet fuel boiling-range hydrocarbons, which may optionally be separated (e.g., by fractionation) for use as transportation fuels, or otherwise as blending components for such fuels. Particular aspects of the invention are associated with advantages arising from maintaining reaction conditions that improve the yield of Chydrocarbons. Further aspects relate to the advantages gained by integration of the appropriate reactions to carry out the methane conversion, with downstream separation to recover and recycle desirable components of the reaction effluent, thereby improving process economics to the extent needed for commercial viability.
