A system and method for producing olefin via dry reforming and olefin synthesis in the same vessel, including providing feed including methane and carbon dioxide to the vessel, converting methane and carbon dioxide in the vessel into syngas (that includes hydrogen and carbon monoxide) via dry reforming in the vessel, and cooling the syngas via a heat exchanger in the vessel. The method includes synthesizing olefin from the syngas in the vessel, wherein the olefin includes ethylene, propylene, or butene, or any combinations thereof.

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.

A method is disclosed for rejuvenation a cobalt Fischer Tropsch catalyst used in a Fischer Tropsch process operating in recycle mode. The method permits the use of specific inert gases to adjust the mole weight of the gas so that the recycle compressor designed for normal steady state operation can also be used in the method. Hydrogen from a membrane permeate stream is added to the reactor loop at a temperature between 300 F and 400 F and the carbon oxides are reacted out to purify the hydrogen. This stream is continuously recycled and the temperature is raised to between 425 F and 500 F and held at the final temperature for between 4 hours and 48 hours. The cobalt Fischer Tropsch catalyst is effectively rejuvenated in-situ by the method.

Separation of carbon dioxide from the exhaust of an internal combustion engine, the production of hydrogen from water, and reformation of carbon dioxide and hydrogen into relatively high-octane fuel components.

A hydrocarbon production system capable of efficiently producing hydrocarbon containing a high-calorie gas by securing hydrogen and carbon monoxide required for hydrocarbon synthesis using water and carbon dioxide as raw materials is obtained. The hydrocarbon production system includes an electrolytic reaction unit that converts water and carbon dioxide into hydrogen and carbon monoxide through an electrolytic reaction, a catalytic reaction unit that converts a product generated by the electrolytic reaction unit into hydrocarbon through a catalytic reaction, and branch paths and that branch a portion of an outlet component of the catalytic reaction unit.

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.

The present disclosure relates to a reactor and a method of operation for an exothermal process being catalyzed by a catalytically active material receiving a reactant gas and providing a product gas, in which said exothermal process has a heat development having a potential for thermally degrading said catalytically active material, and which exothermal process operates at a temperature at which the reactants and at least 80% or all of the products are present as gases, said method comprising the steps of a) directing the reactant gas to a first zone of a material catalytically active in the exothermal process producing an first product gas, and b) directing the first product gas to a second zone of a material catalytically active in the exothermal process producing a product gas, with the option of fully or partially by-passing either said first zone or said second zone, while directing a non-condensing gas stream having a temperature at least 50° C. lower than the product gas to said by-passed zone, wherein the choice of by-passing said zone is made based on the time of operation or a process parameter reflecting the catalytic activity of the zone of catalytically active material which is not by-passed with the associated benefit of reducing the extent of thermal deactivation of the catalytically active material, and thus increasing the overall lifetime of the catalytically active material.
