COATING METHOD MOVING CHANNEL IN INTEGRATION TYPE CATALYST CARRIER WITH COATING DISPERSIVE SOLUTION

摘要

PURPOSE: The catalyst carrier having more cell density is provided for increasing the processing efficiency in processing exhaust gas from an internal combustion engine. CONSTITUTION: The new coating method of honey comb shaped ceramic and metal catalyst, has under 10 seconds of a period and also has more than 180 cm¬-2 of the cell density of reproductivity coating material of a carrier has the steps of: coating the moving channel in an integration type cylindrical catalyst carrier having two end faces connected each other through a moving channel arranged in parallel to the axis of the cylinder; vertically arranging the axis of the cylindrical carrier; putting the coating dispersion solution predetermined from a storage container at the upper end face of the carrier; exhausting the dispersion solution through the moving channel under inhaling; vacating the moving channel under inhaling the excessive amount of the coating dispersion solution; removing from the moving channel; restoring the excessive amount of the dispersion solution to the storage container; fixing the coating dispersion solution.
