    摘要： The invention relates to a process for coating ceramic honeycomb bodies with a coating suspension containing, in a carrier liquid, catalyst components as solids and/or in dissolved form. The honeycomb bodies have parallel flow channels running through them. The walls of the flow channels generally have an open pore structure. To coat the channel walls and in particular also the interior surfaces of the pores with the coating suspension, it is proposed that the flow channels be temporarily alternately closed and the coating suspension be forced through the open pore structure of the channel walls. The coating is subsequently dried and calcined. To close the flow channels, it is possible to use thermally or chemically decomposable or soluble compositions which are decomposed or dissolved either during calcination or by means of a subsequent chemical treatment. The coated honeycomb bodies are preferably used for the purification of exhaust gases from automobiles.

    摘要： Soot filters for removing soot from the exhaust gas of lean-burn engines become blocked with progressive operating duration on account of the deposition of soot, and must therefore be regenerated at regular intervals. It has been found that reliable operation of the soot filter is possible only if an active regeneration is carried out from time to time by increasing the exhaust-gas temperature to the soot ignition temperature. For this purpose, an oxidation catalytic converter is usually arranged upstream of the soot filter, and the exhaust-gas temperature is increased by means of the catalytic combustion of additionally injected fuel. Here, the oxidation catalytic converter is subjected to high temperature loading and therefore ages very quickly. It has surprisingly been found that the ageing of the oxidation catalytic converter can be slowed if said oxidation catalytic converter is split into at least two separate catalytic converters and the distance between said separate catalytic converters is 2 to 30 mm.
