METHOD FOR PRODUCING EXHAUST GAS PURIFICATION CATALYST

WIPO Patent Application WO/2023/153244

A1

The present disclosure provides a method for producing an exhaust gas purification catalyst in which the standby time of a shower nozzle is reduced. The production method disclosed herein includes: a slurry supply step in which a catalyst metal-containing slurry is supplied from a shower nozzle to one end of one honeycomb substrate; a first suction step in which pressurization or decompression is performed toward the other end of the honeycomb substrate using a first suction device in the one honeycomb substrate to which the slurry is supplied and the supplied slurry is pulled into the interior of the honeycomb substrate; and a second suction step in which pressurization or decompression is performed again toward the other end of the honeycomb substrate using a second suction device in the one honeycomb substrate after the first suction step and the supplied slurry is pulled into the interior of the honeycomb substrate. In addition, the slurry supply step and the plurality of suction steps are performed in parallel on the same production line.
