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.
