DEVICE AND METHOD FOR OBTAINING HYDROGEN-CONTAINING GAS Russian patent published in 2018 - IPC C01B3/50 

FIELD: technological processes.

SUBSTANCE: invention relates to a device and method for producing a hydrogen-containing gas. Method comprises the supply of steam-methane mixture into the annular space of a coaxial mixer mounted on the upper reactor vessel. Then, the steam-air mixture is supplied to the central pipe, as well as the ignition feed to the methane oxidation chamber of the upper reactor vessel, in which the methane combustion reaction takes place over the upper catalyst sublayer. At the same time, the reagent stream resulting from the reaction enters to mix with an additional volume of methane, which occurs in the free space between the upper reactor vessel and the lower reactor vessel. Then the mixed stream of reagents and methane enters the lower sublayer of the catalyst for methane conversion in the lower reactor vessel, by means of which an additional methane conversion reaction is performed due to the physical heat of the gas mixture of the reagent stream and from which the production gas is discharged through the outlet pipe.

EFFECT: technical result consists in increasing the efficiency of conversion of lower alkanes and the thermodynamic efficiency of the methane conversion reactor, as well as increasing the ratio H₂/CO in the produced gas.
