Abstract
The present invention provides a process for regenerating the catalytic activity of catalysts that have oxidizing functions. A catalyst that is located in the exhaust gas line of a diesel engine that preferably contains a catalytically active coating on a honeycomb carrier that does not have a filter function and that has at least one oxidizing function is regenerated. As a result of time-restricted increases in the exhaust gas temperature upstream of the catalyst to a value greater than 450° C., the combustion of soot particles and hydrocarbons deposited on the catalyst is initiated, and thus, the catalytic activity of the catalyst is at least partly regenerated.
