A reactor (1), for the partial oxidation of a hydrocarbon-containing gas mixture stream, in particular in a mobile reformer unit (2), comprising a housing (3), with an inner surface (4) and a honeycomb body (5) with an inlet end face (6) and an outlet end face (7), whereby the honeycomb body (5) is at least partly surrounded by the inner surface (4) of the housing (3) and the gas mixture stream may flow through the above body, is characterised in that the honeycomb body (5) has at least one free emitting surface (8) for heat dissipation, directed towards the inner surface (4) of the housing (3). At a temperature of 600 DEG Celsius the inner surface (4) has an emissivity of greater than 75 %, preferably greater than 80 % and in particular greater than 85 %. As transient temperatures of ca. 1300 DEG Celsius can be achieved during partial oxidation and the honeycomb body radiates heat at an increased rate in this temperature range, which is absorbed by the housing, the reactor as above is protected against an overheating of the honeycomb body. |
