4 Claims

1. A method for coating a monolithic porous catalyst support having a plurality of channels formed in a longitudinal direction with a catalyst slurry, the coating method comprising:

inputting the catalyst slurry into a container having a bottom thereof moved up and down;

moving a lower end of the catalyst support and an upper end of the container to be horizontally leveled;

sealing the lower end of the catalyst support and the upper end of the container from outside; and

applying a positive pressure at an upper end of the catalyst support while moving the bottom of the container upward.
