METHOD OF OBTAINING HYDROGEN AND HYDROGEN-METHANE MIXTURE Russian patent published in 2014 - IPC C01B3/38 C10K3/02 

FIELD: chemistry.

SUBSTANCE: invention can be used in the chemical industry. A method of obtaining a hydrogen-methane mixture includes application of two parallel flows, which contain lower alkanes, as a source of raw material. The first flow is directed to partial oxidation with oxygen containing gas. Products of the first flow oxidation are supplied to cooling by means of the second flow heating, and after that, to catalytic conversion of carbon monoxide. After that, hydrogen is separated from the first flow. The second flow is mixed with water vapour and successively passed through a series of successive stages, each of which includes heating in a heat exchanger due to discharge of heat from the process of the partial first flow oxidation, and then through an adiabatic conversion reactor, filled with a catalyst filling. Products of the second flow conversion after separation of water vapour are mixed due to ejection with hydrogen, discharged from the first flow.

EFFECT: invention makes it possible to increase a coefficient of conversion of low alkanes and reduce the content of ballast gases, such as nitrogen and argon, in produced gas.
