Abstract: Compositions, devices, and methods relating to the use of mixed-matrix membranes containing metal-organic frameworks to separate gases are generally described. In some embodiments, branched nanoparticles made at least in part of metal-organic frameworks are described. In some embodiments, the morphology and size of the branched nanoparticles are controlled by the presence of a chemical modulator during synthesis. In some embodiments, the branched nanoparticles are uniformly distributed in a mixed-matrix membrane. In some embodiments, the mixed-matrix membrane is configured to separate one or more gases from a gas mixture. In some embodiments, the branched nanoparticles contribute at least in part to an increase in permeability, selectivity, and/or resistance to plasticization of the mixed-matrix membrane.

Abstract: Systems and methods for producing methane and sulfur. A first system includes a condensate separation system to separate a feed stream of mixed hydrocarbons, an acid gas removal system to produce a methane product stream and a reactant gas stream of carbon dioxide and hydrogen sulfide and a catalytic reactor configured to react the carbon dioxide and the hydrogen sulfide from the reactant gas stream using a carbon-based catalyst and produce an effluent methane stream, an effluent sulfur stream, and a waste stream. Another system for producing methane and sulfur includes a first separation system to separate water vapor and oxygen to produce a hydrogen sulfide stream, a catalytic reactor configured to react a separated carbon dioxide stream and the hydrogen sulfide stream using a carbon-based catalyst and produce a methane stream and a sulfur stream.
