    Abstract: A method for impregnating the interior skeletal structure of a ceramic monolithic catalyst support with a slurry of catalyst material is disclosed wherein a predetermined amount of catalyst slurry is metered into contact with a first end of the support. A cover is placed over the periphery of a second, opposite end of the support in sealing relation thereto to define a vacuum chamber adjacent the second end.
