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.

A methanation reactor for reacting dihydrogen with a carbon-based compound and producing methane. The reactor has a hollow body configured to receive a fluidized bed of catalytic particles, an inlet for each carbon-based compound and dihydrogen, and an outlet for methane and water. A water inlet is provided to inject liquid-phase cooling water into the fluidized bed. When each carbon-based compound is a gas, the reactor has at least one water-injection nozzle and at least one gas injection nozzle for a gas consisting of the carbon-based gas and dihydrogen, and at least one water-injection nozzle positioned below the gas-injection nozzle. The flow rate of water introduced into the hollow body can depend on the temperature measured in the reactor.

The present invention relates to a new salt of perindopril and to pharmaceutical compositions containing it, and Medicaments for treatment of hypertension and heart failure.

Salt of perindopril and pharmaceutical compositions containing it

Gas burner comprising a gas distribution chamber (3) fed with combustive air and combustible gas and communicating with a combustion chamber (15) through a main flame stabilization grille (11) having a lacunar structure, porous to the air/gas mixture. Preferably, the means (23) for ignition of the burner will be disposed outside the distribution chamber but will pass through the grille (11), the ignition being carried out either from one side of this grille, or from its periphery.
