A method for metering a reagent into a flowing medium includes adjusting a quantity of a reagent to be metered per unit of time into a flowing medium as a function of a thickness of a reaction zone in a catalytically active material. An apparatus for metering a reagent into a flowing medium includes a control unit, a device associated with the control unit for detecting a thickness of a reaction zone, and a metering device associated with the control unit for introducing a reagent into a flowing medium upstream of a catalytic converter as seen in flow direction of the medium. The control unit adjusts a quantity of the reagent to be metered into the flowing medium per unit of time by the metering device, as a function of a thickness of the reaction zone.

[ I claim:] [1.] A method for metering a reagent into a flowing medium and for reacting the reagent with an agent contained in the flowing medium to produce a catalytic conversion of the agent, which comprises:contacting a flowing medium having an agent with a catalytically active material of a catalytic converter for reacting the agent with a reagent to produce a catalytic conversion of the agent;metering the reagent into the flowing medium upstream of the catalytic converter;detecting a thickness of a reaction zone in the catalytically active material, the thickness of reaction zone defining a depth of the reagent absorbed in the catalytically active material; andadjusting a quantity of the reagent to be metered per unit of time into the flowing medium as a function of the thickness of the reaction zone of the catalytically active material.
