<p>The invention relates to a reactor for catalytic methanation of a gas mixture containing carbon dioxide and hydrogen by means of a reactor vessel. A catalyst that catalyses the methanation reaction is arranged in a main flow path extending from the reactor inlet for introducing the gas mixture to a reactor outlet for discharging the methanated gas mixture. The reactor vessel further comprises at least one spatial region that is located remotely from the main flow path but is open for the gas mixture on an inflow side toward the main flow path. The reactor can be flushed with a flushing gas by means of a flushing arrangement. The flushing arrangement has an access for guiding the flushing gas into the remotely located spatial region and/or out of the remotely located spatial region on a side that does not coincide with the inflow side. The invention further relates to a method for operating the reactor according to the invention.</p> |
