Apparatus and method for quantitatively coating catalyst support

Abstract

Disclosed herein is a method of coating a catalyst support, in which a monolithic catalyst support provided therein with a plurality of longitudinally formed channels is quantitatively coated with catalyst slurry applied to post-treatment of exhaust gas, including the steps of: introducing catalyst slurry into a quantitative container whose bottom is vertically moved; moving a catalyst support to the top of a container such that the bottom of the catalyst support and top of the container are horizontally disposed each other; sealing the bottom of the catalyst support and the top of the container from the outside; moving the bottom of the container upward; and applying a vacuum to the channels of the catalyst support.

         5 . An apparatus for coating a catalyst support, the catalyst support having a top and a bottom, the apparatus comprising:
 a means for introducing a quantitatively-determined amount of catalyst slurry;   a volume-adjustable container including an open top for introducing the quantitatively-determined amount of catalyst slurry and a movable bottom;   a support fastener for moving the catalyst support to the open top of the volume-adjustable container so that the bottom of the catalyst support is horizontally matched with the open top of the volume-adjustable container;   a means for moving the movable bottom of the volume-adjustable container, the means having a shaft connected with the movable bottom of the volume-adjustable container; and   a vacuum means located over the open top of the volume-adjustable container.   
     
     
         6 . The apparatus of  claim 5 , further comprising sealing means for sealing the open top of the volume-adjustable container and the bottom of the catalyst support.
