A device includes a gasifier to produce a gaseous compound from a biomass. The gasifier includes inlets for the biomass and for an oxidizing agent and an outlet for the gaseous compound including carbon monoxide. A first methanation unit to methanate the carbon monoxide to produce a substitute natural gas exiting the gasifier. The first methanation unit includes at least one inlet for water and an inlet for the gaseous compound coming from the gasifier. A second methanation unit to methanate the carbon dioxide to produce the substitute natural gas. The second methanation unit includes at least one inlet for water and one inlet for the carbon dioxide from the first methanation unit. A dihydrogen producing unit to produce dihydrogen from water and electric current. The dihydrogen producing unit includes an electrical power supply, an inlet for water and an outlet for dihydrogen supplying the second methanation unit.

Device and method for producing substitute natural gas and network comprising same

A method for treating a synthesis gas from a gasification step. The synthesis gas is cooled to condense heavy organic impurities and water. At the end of the cooling step, light organic impurities and inorganic impurities are adsorped by at least one adsorption bed. The water and heavy tars are separated by decantation from the step of cooling the synthesis gas. At least one adsorption bed is regenerated by temperature-modulated or pressure-modulated desorption.
