    Abstract: The invention relates to a method for removing carbonaceous deposits from surfaces of catalysts and plant components by treating the deposits with a superheated steam flow at least temporarily containing an oxygenated gas, wherein by monitoring the CO2 in the exhaust gas after condensing the steam at a temperature of at least 300 °C, (a) the carbonaceous deposits are treated with super-heated steam at a temperature of at least 300 °C until the CO2 content of the exhaust gas has exceeded a maximum, (b) then with further introduction of super-heated steam the introduction of oxygen begins, wherein the amount of introduced oxygen is adjusted so that the CO2-content in the exhaust further reduces until it has sunk to a value
