DEVICE AND METHOD FOR PRODUCING METHANE Russian patent published in 2017 - IPC C12P5/02 C12M1/42 C12M1/107 C12N1/20 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to biochemistry. An device and a method of producing methane (versions) is offered. The device includes a cathode reaction vessel to place carbon dioxide and aqueous electrolyte, an anode reaction vessel to place aqueous electrolyte, and also connection means for flow of direct current between the vessels. The cathode in the corresponding vessel is the base of methanogens of anaerobic Archaea. Cathode and anode reaction vessels are adapted to create a pressure of from 5 to 1000 bar in them. In one version, the method comprises passing direct current through anode and cathode, ensuring the ionization of hydrogen in the cathode reaction vessel, increasing the pH value of the aqueous electrolytic growing substrate, and forming oxygen out from the ionized oxygen in the anode reaction vessel. In another version, the method comprises feeding of aqueous growing substrate with methanogens of anaerobic Archaea into the reaction vessel, which is subjected to a pressure of from 5 to 1000 bar by means of compressive fluid media. In this case fluid media consists of carbon dioxide or mixture of carbon dioxide and hydrogen.

EFFECT: invention provides a reduction of content of carbon dioxide in the atmosphere, as well as the lack of fossil fuel use in the preparation of methane.
