DEVICE AND METHOD OF PRODUCING HYDROGEN AND NON-VOLATILE CARBON FROM GAS CONTAINING C-C-ALKANES Russian patent published in 2024 - IPC C01B3/24 C01B3/34 C01B3/50 C09C1/48 B01J19/18 H01J37/32 H05H1/40 H05H1/42 

FIELD: chemistry.

SUBSTANCE: group of inventions can be used in producing hydrogen. Device for production of hydrogen and solid carbon from gas containing C₁-C₄-alkanes by means of thermal plasma includes at least one reactor for generation of thermal plasma by means of electric arc. Reactor includes a plasma section and a second reactor section directly downstream of the plasma section in the direction of flow of the main flow. Second reactor section includes the first subsection and the second subsection, besides, the second subsection is located directly downstream of the first subsection in the direction of flow of the main flow. Also disclosed is a method of producing hydrogen and solid carbon and use of the device in said method.

EFFECT: inventions make it possible to increase efficiency of hydrogen production from gas containing C₁-C₄-alkanes, to increase degree of initial raw material conversion with high output per one pass per unit of time, to reduce formation of undesirable by-products.
