Abstract: The invention relates to a process for coating the flow channels in a monolithic, cylindrically shaped catalyst carrier with a coating dispersion, wherein the carrier has two end faces which are connected to each other by flow channels arranged parallel to the axis of the cylinder, by vertically aligning the axis of the cylindrical carrier, placing a predetermined amount of coating dispersion from a storage container on the upper end face of the carrier and drawing the dispersion through the flow channels under suction, removing excess coating dispersion from the flow channels by emptying the flow channels under suction, returning the excess dispersion to the storage container and fixing the dispersion coating by calcination. The process is characterised in that the coating dispersion is drawn through the flow channels under suction at a rate of flow of 0.1 to 1 m/s and that after completion of passage under suction the excess coating dispersion is removed from the flow channels by applying a suction impulse from below, wherein the suction air is drawn through the flow channels under suction at a rate of flow between 40 and 1 m/s and the excess coating dispersion discharged with the air stream is separated from the air stream within a time of less than 100 ms after discharge from the catalyst carrier.

Abstract: The coating dispersion is sucked through the flow channels of a monolithic catalyst support at a rate of 0.1-1 m/s. Excess dispersion is removed from the channels by applying a suction impulse from below. Extraction air is sucked at a rate of 40-1 m/s through the channels and the excess coating dispersion removed from the air stream is removed from the air stream within a time from less than 100 ms after leaving the catalyst support. Process for coating the flow channels of a monolithic cylindrical catalyst support with a coating dispersion comprises vertically directing the cylindrical axis, charging a predetermined amount of dispersion from a storage vessel to the upper front surface of the support, sucking the dispersion through the flow channels, removing excess dispersion from the channels, returning the excess dispersion to the storage vessel and fixing the dispersion by calcining. The coating dispersion is sucked through the flow channels of a monolithic catalyst support at a rate of 0.1-1 m/s. Excess dispersion is removed from the channels by applying a suction impulse from below. Extraction air is sucked at a rate of 40-1 m/s through the channels and the excess coating dispersion removed from the air stream is removed from the air stream within a time from less than 100 ms after leaving the catalyst support.
