Abstract: Reactors and methods that generate hydrogen from fuel, such as naturally-occurring or synthesized hydrocarbon fuel. One embodiment of the reactor comprises a CO2/H2 active membrane piston disposed inside a cylinder that provides for highly efficient and scalable hydrogen generation from hydrocarbon fuels. This embodiment may function in a two or four stroke modes. Another embodiment of the reactor comprises a dual piston configuration having CO2 and H2 active membrane pistons inside a single cylinder. Other embodiments of the reactor comprise flexible membranes or diaphragms that operate in a manner similar to pistons with or without regeneration of residual reaction products. Exemplary methods introduce fuel into a controllable volume, selectively control pressure, temperature and residence time of the fuel within the controllable volume, chemically react the fuel within the controllable volume with one or more catalysts to produce one or more chemical species, selectively remove via a membrane one or more of the chemical species from the controllable volume, and exhaust residual products from the controllable volume.

Abstract: In a first stage of a methane conversion system, at least some methane (CH4) in an input gas flow stream can be converted into C2 hydrocarbons, hydrogen gas (H2), and aromatics to provide a first processed stream. The conversion can be direct non-oxidative methane conversion (DNMC). At least some of the aromatics can be removed from the first processed stream to provide a second processed stream. In a second stage of the methane conversion system, at least some of the H2 can be removed from the second processed stream to provide a recycle stream. The recycle stream can be returned to the first stage of the methane conversion system for further conversion of methane and removal of aromatics and H2 products.

Abstract: A catalytic membrane composite that includes porous supported catalyst particles durably enmeshed in a porous fibrillated polymer membrane is provided. The porous fibrillated polymer membrane may be manipulated to take the form of a tube, disc, or diced tape and used in multiphase reaction systems. The supported catalyst particles are composed of at least one finely divided metal catalyst dispersed on a porous support substrate. High catalytic activity is gained by the effective fine dispersion of the finely divided metal catalyst such that the metal catalyst covers the support substrate and/or is interspersed in the pores of the support substrate. In some embodiments, the catalytic membrane composite may be introduced to a stirred tank autoclave reactor system, a continuous flow reactor system, or a Parr Shaker reaction system and used to effect the catalytic reaction.

Abstract: The invention is a high-throughput voltage screening crystallographic device and methodology that uses multiple micro wells and electric circuits capable of assaying different crystallization condition for the same or different proteins of interest at the same of different voltages under a humidity and temperature controlled environment. The protein is solubilized in a lipid matrix similar to the lipid composition of the protein in the native environment to ensure stability of the protein during crystallization. The invention provides a system and method where the protein is transferred to a lipid matrix that holds a resting membrane potential, which reduces the degree of conformational freedom of the protein. The invention overcomes the majority of the difficulties associated with vapor diffusion techniques and essentially reconstitutes the protein in its native lipid environment under “cuasi” physiological conditions.
