Abstract: A method for treating a catalyst base that comprises a contact area of porous material. A fluid, such as a flue gas stream, can be conducted along the contact area. A catalytically relevant substance is introduced into pores of the catalyst base using a transport fluid and remains on pore wall areas after removal of the transport fluid. The introduction is carried out such that an amount of the catalytically relevant substance relative to the surface remains on the pore wall areas as a function of location within the pore and decreases within the pore after exceeding a specific pore depth. A blocking fluid can first be introduced into pore regions beyond the specific pore depth, thus blocking these regions when transport fluid containing the catalytically relevant substance is introduced.

Abstract: A method for treating catalysts, in particular, for the cleaning and/or regeneration of a catalyst, whereby the catalyst comprises parallel channels. The catalyst is taken out of service for treatment and flushed with a cleaning and/or regeneration fluid in-situ in the assembled state. The cleaning and/or regeneration fluid is introduced under pressure to that end of a bundle of adjacent channels away from the pressurized end of the catalyst. The channels of the bundle are flushed against gravity and the cleaning and/or regeneration fluid escapes from the other end of the channels thereupon enters the free ends of other adjacent channels and flows through the same under the effect of gravity.
