Abstract
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.
