摘要： Disclosed are materials and methods for separating hydrogen sulfide from a hydrocarbon-based gas mixture by contacting the hydrocarbon-based gas mixture with a membrane formed from a polymer of intrinsic microporosity (PIM) or an amidoxime-functionalized polymer of intrinsic microporosity (AO-PIM), wherein the membrane separates the hydrocarbon-based feedstock into a permeate stream that comprises at least some of the hydrogen sulfide and a retentate stream that is depleted in hydrogen sulfide as compared to the hydrocarbon-based gas mixture.

摘要： A method includes providing a stream containing carbon dioxide and at least one other condensable component; pressuring the stream containing carbon dioxide and at least one other condensable component to thereby produce a pressurized stream; and indirectly exchanging thermal energy between the pressurized stream and a thermal- energy accepting stream including a boilable component. A method includes providing a first stream containing carbon dioxide; adsorbing at least a portion of the carbon dioxide in the first stream in an adsorbing means; desorbing at least a portion of the carbon dioxide in the adsorbing means to obtain a desorbed carbon dioxide stream; and compressing the desorbed carbon dioxide stream immediately following said step of desorbing.

摘要： The present relates to a nanoporous carbon membrane manufacturing method comprising coating a block copolymer film with hydrophilic and hydrophobic blocks, on a sacrificial non-porous substrate so as to prepare an block copolymer film coated foil, transferring the block copolymer film on a porous support, pyrolizing the block copolymer film to form a nanoporous carbon film, wherein the transfer step consists in a wet-transfer process comprising placing the block copolymer film coated foil in an etchant bath in an etching chamber and the porous support above the height of said etching bath, etching the underlying sacrificial foil of block copolymer film coated foil, raising the height of the etching bath above the porous support, bringing the free-floating etched block copolymer film on top of the porous support, and lowering the etching bath height below the porous support so as to deposit the copolymer film on top of the porous support.

摘要： Oxygen is removed from a gas feed such as a landfill gas, a digester gas or an industrial CO 2 off-gas by removing sulfur-containing compounds and siloxanes from the feed gas, heating the feed gas, optionally removing siloxanes and silanols from the heated feed gas, optionally removing part of the sulfur-containing compounds in the heated feed gas, optionally converting any or all of the volatile organic compounds (VOCs) present in the gas, including sulfur-containing compounds and/or chlorine-containing compounds, in the heated feed gas, injecting one or more reactants for oxygen conversion into the heated feed gas, carrying out a selective catalytic oxygen conversion in at least one suitable reactor, and cleaning the resulting oxygen-depleted gas. The reactants to be injected comprise one or more of H 2 , CO, ammonia, urea, methanol, ethanol and dimethyl ether (DME).
