ABSTRACT:
The present invention relates to a method for removing clogging dust in gas passing holes in a honeycomb catalyst. A honeycomb catalyst whose gas passing holes are clogged with dust in exhaust gas is immersed in water in a vessel, and then the vessel is closed and vacuum suction is exerted, by which water is allowed to flow in the gas passing holes in the honeycomb catalyst to remove dust in the gas passing holes.
