Abstract
A method for preparing monolithic catalyst washcoat is disclosed and includes the following steps: preparing a coating slurry; pretreating a monolithic carrier; applying the coating slurry onto the monolithic carrier by vacuum spraying; removing the excess coating slurry by vacuum extraction; and obtaining the monolithic carrier applied with the washcoat after drying and calcination. The washcoat of 5-20 wt % can be obtained on the monolithic carrier of the present invention by one-off applying. The method can be used to prepare the washcoat on monolithic cordierite ceramic carrier, monolithic metal carrier, monolithic active carbon carrier or monolithic molecular sieve carrier. The obtained washcoat is uniform, and has good adhesion with the carrier and excellent repeatability.
