The process for operating a purification apparatus for gases comprises passing the gas stream through a filter body containing a catalyst and catalytically converting the pollutants. At low temperature, especially below 200 degrees C, more especially below 150 degrees C, hydrocarbons are stored in the filter body (2) and released above these temperatures, and pollutants are catalytically converted with the aid of the carrier material of the filter body. Also claimed is the purification apparatus consisting of a filter body (2) made from a carrier material which stores at least 20 vol.%, preferably at least 50 vol.% of the hydrocarbons at below 200 degrees C, especially below 150 degrees C. The carrier material effectively reduces the pollutants with the aid of a reductant, preferably hydrocarbons and/or carbon monoxide.
