A reactor for hydrocarbon production that separates wax reaction products from lightweight gaseous reaction products. The reactor has a housing, a catalyst bed, a product recovery zone, and a stripping zone. The catalyst bed can be provided in multi-tubular and other fixed bed configurations. The stripping zone receives light-weight gas reaction products from the product recovery zone, while a gas outlet of the housing receives non-lightweight gaseous hydrocarbon reaction products from the product recovery zone. A wax outlet of the housing receives wax products from the product recovery zone.

A process is described for treating a natural gas stream containing methane and one or more higher hydrocarbons including the steps of mixing at least a portion of the natural gas stream with steam; passing the mixture adiabatically over a supported precious metal reforming catalyst to generate a reformed gas mixture comprising methane, steam, carbon dioxide, carbon monoxide and hydrogen; cooling the reformed gas mixture to below the dew point to condense water and removing the condensate to provide a de-watered reformed gas mixture, and passing the de-watered reformed gas mixture through an acid gas recovery unit to remove carbon dioxide and at least a portion of the hydrogen and carbon monoxide, thereby generating a methane stream. The methane stream may be used to adjust the composition of a natural gas stream, including a vaporized LNG stream, to meet pipeline specifications.

A combined anaerobic digester system and gas-to-liquid system is disclosed. The anaerobic digester requires heat, and produces methane. The gas-to-liquid system produces heat, and converts methane to higher-value products, including methanol and formaldehyde. As such, the combination of the two systems results in significant savings in terms of capital and operating expenses. A process for producing bio-formaldehyde and bio-formalin from biogas is also disclosed.

The invention relates to a novel reactor design, wherein the pressurized chamber contains both a high-temperature electrolysis (HTE) reactor with elementary electrolysis cell stacking for producing either hydrogen or a synthesis gas (syngas for a H.sub.2+CO mixture) from water vapor H.sub.2O and carbon dioxide CO.sub.2, and at least one catalyst arranged at a distance and downstream of the outlet of the electrolyzer for converting the previously produced synthesis gas into the desired combustible gas, by means of heterogeneous catalysis, the synthesis gas having being produced either directly from the electrolysis reactor or indirectly by mixing the hydrogen produced with carbon dioxide CO.sub.2 injected into the chamber.

A hydrocarbon reclamator consists of a closed chamber having an exhaust inlet port, a hydrogen inlet port, and a hydrocarbon outlet port. A magnetic flux is generated at the base of the closed chamber and a rotor is suspended by the magnetic flux within the closed chamber. The rotor is formed as a Tesla turbine having axially spaced discs concentrically mounted on a central shaft, a catalyst is formed on surfaces of the discs, and flow holes are formed through the discs. Venturi forces direct gas to release kinetic energy against the discs, so that hydrogen entering the chamber combines with carbon entering the chamber to form a hydrocarbon that exits the chamber via the hydrocarbon outlet port.
