The invention relates to the chemical industry and can be used for processing methane and other volatile, liquid, solid fusible hydrocarbons when producing hydrogen, soot, and other flammable gases. The invention relates to a method for the pyrolytic decomposition of hydrocarbons, in which a pyrolysis reactor arranged in a space bounded by a lining is heated by flue gases generated by combusting a hydrogen-enriched mixture of air and gaseous hydrocarbons, while ensuring a maximum decrease in CO.sub.2 emissions into the atmosphere. The invention also relates to a unit for the pyrolytic decomposition of hydrocarbons. The technical result is a high degree of separation of hydrogen and carbon by fast high-temperature pyrolysis at atmospheric pressure without oxygen supply and without CO.sub.2 production.

There are provided systems and methods for using fuel-rich partial oxidation to produce an end product from waste gases, such as flare gas. In an embodiment, the system and method use air-breathing piston engines and turbine engines for the fuel-rich partial oxidation of the flare gas to form synthesis gas, and reactors to convert the synthesis gas into the end product. In an embodiment the end product is methanol.

A furnace for gas fields, refineries reforming, petrochemical plants, or hydrogen generation by gasification may include: a radiant zone; a convective zone; and a first and second series of pipes through which at least two segregated process gas flows respectively pass. A first process gas flow may enter the furnace through the convective zone and, flowing through the first series of pipes, may leave the furnace through the radiant zone, or alternatively the first process gas flow may enter the furnace through the radiant zone and, flowing through the first series of pipes, may leave the furnace through the radiant zone. At least a second process gas flow may enter the furnace through the convective zone, may pass through the second series of pipes, and may leave the furnace through the convective zone. The second of series of pipes may be made of material resistant to acid gases.

Modified red mud catalyst compositions, methods for production, and methods of use in dry reforming, the composition comprising: red mud material produced from an alumina extraction process from bauxite ore; and nickel oxide, the nickel oxide present at between about 5 wt. % to about 40 wt. % of the modified red mud catalyst composition.

Systems and methods for sequestering carbon, evolving hydrogen gas, producing iron oxide as magnetite, and producing magnesium carbonate as magnesite through sequential carbonation and serpentinization/hydration reactions involving processed olivine- and/or pyroxene-rich ores, as typically found in mafic and ultramafic igneous rock. Precious or scarce metals, such nickel, cobalt, chromium, rare earth elements, and others, may be concentrated in the remaining ore to facilitate their recovery from any gangue material.

Process control parameters for production of hydrogen and FT products by steam/CO2 reforming include controlling steam reformer temperature, addition of steam, CO and optionally, biogas. Optimization of parameters have resulted in increased production of H.sub.2, removal of sulfur and halogen contaminants, and control of the H.sub.2/CO ratio for efficient generation of Fischer-Tropsch products.

A method for preparing hydrogen-rich synthesis gas by degrading waste polyolefin plastics at a low temperature includes the following steps: weighing 1 part by weight of polyolefin waste plastics and 3 parts-80 parts by weight of hydrogen peroxide containing 0.25%-6% of H.sub.2O.sub.2; feeding the polyolefin waste plastics and the hydrogen peroxide into a hydrothermal reactor, and carrying out the oxidation pretreatment reaction at a reaction temperature of 150° C.-230° C. under a reaction pressure of 0.5 MPa-2 MPa for 30 minutes-90 minutes, and obtaining an aqueous-phase product and a gas-phase product after the reaction is finished; filling another hydrothermal reactor with a mesoporous carbon supported metal-based catalyst, and then introducing the aqueous-phase product into the hydrothermal reactor for a reforming reaction to obtain a hydrogen-rich synthesis gas product. In the whole process, the H.sub.2 yield is close to 11 mol/kg plastics, and the H.sub.2 concentration in the hydrogen-rich synthesis gas is close to 55%.

A device for processing waste is described herein that comprises an ion generator, a furnace chamber, a heat exchanger, a pollution control system, and a chimney. The ion generator converts atmospheric air into an ionized gas and the furnace chamber thermally decays the waste by combining the waste with a product of an interaction of the ionized gas and heat generated by the furnace chamber. The heat exchanger cools the excess gas. A wet scrubber system removes heavy metals and/or acid gases from the cooled excess gas to generate scrubbed excess gas, and a fixed bed coke system detoxifies the scrubbed excess gas by converting carbon monoxide, water, and steam in the scrubbed excess gas to carbon dioxide and hydrogen, and removing remaining acid gas, a remaining heavy metal, and/or a remaining dioxin from the scrubbed excess gas. The chimney transfers remaining scrubbed excess gas out of the device.
