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

摘要

The present invention relates to a methanation reactor (10) for reacting dihydrogen with one or more carbon-based compounds to produce methane, said methanation reactor (10) comprising: for dihydrogen and each carbon-based compound; a hollow body (105) comprising an inlet (110) and configured to receive a fluidized bed of catalyst particles (106); and outlets 115 for methane and water. The reactor 10 further includes an inlet 120 for injecting liquid cooling water into the fluidized bed. In certain embodiments, each carbon-based compound is a gas, and the reactor 10 includes one or more injection nozzles 110 and one or more water-injection nozzles 120 for gases comprising dihydrogen and carbon-based gases. ), wherein the one or more water-injection nozzles are located below the one or more gas-injection nozzles. In certain embodiments, the flow rate of water entering the hollow body is dependent on the temperature measured within the reactor 10 .
