摘要： A process for the coating of the flow channels of a cylindrical, honeycomb form catalyst carrier with a dispersion coating through filling of the vertically oriented flow channels with a fill quantity of the coating dispersion through the bottom face of the catalyst carrier and subsequent downward emptying and clearance extraction of the flow channels, as well as drying and calcination of the catalyst carrier, by the following steps:a) filling of the flow channels with a fill quantity that is about 10% greater than the empty volume of the flow channels, so that the coating dispersion goes over the upper face of the catalyst carrier after completion of the filling cycle,b) removal of the excess coating dispersion at the top before emptying of the flow channels andc) emptying and clearance extraction of the flow channels through an extraction impulse, which is generated by connection of a vacuum tank with the bottom face of the catalyst carrier,whereby the time between the beginning of the fill cycle and the end of the emptying and clearance extraction amounts to no more than 5 seconds.

摘要： A method for the sealing of flow channels in an annular zone of a cylindrical honeycomb body. The sealing of the flow channels takes place by introduction of a ceramic compound into the flow channels by means of a nozzle, wherein nozzle and honeycomb body are moved relative to one another with simultaneous guiding of the nozzle past the lateral surface and/or past the end face contour of the honeycomb body.
