METHANATION REACTOR FOR REACTING HYDROGEN WITH AT LEAST ONE CARBON-BASED COMPOUND AND PRODUCING METHANE AND WATER

摘要

The invention relates to a methanation reactor (10) for reacting dihydrogen with at least one carbon-based compound and producing methane, comprising: a hollow body (105) designed to receive a fluidised bed of catalytic particles (106) and comprising an inlet (110) for each carbon-based compound and for dihydrogen and an outlet (115) for methane and water. The reactor is characterised in that it also comprises an inlet (120) for the injection of liquid-phase cooling water into the fluidised bed. In certain embodiments, each carbon-based compound is a gas, the reactor comprising at least one water-injection nozzle and at least one injection nozzle for a gas comprising the carbon-based gas and dihydrogen, at least one water-injection nozzle being positioned below at least one gas-injection nozzle. In certain embodiments, the flow rate of water introduced into the hollow body depends on the temperature measured in the reactor.
