Water absorption measuring method of porous cell structure, water absorption information display method and catalyst carrying method

摘要

There is disclosed a method in which the water absorption of the porous cell structure is measured as the standard for setting the carrying conditions of the catalyst component in advance, when allowing the porous cell structure for use as a catalyst carrier to carry the catalyst component and forming a catalyst layer by a wash coating process. In the present method, an amount of a particulate material sticking to a surface of a partition wall constituting a cell of the porous cell structure and the surfaces of pores in the partition wall is regarded as the water absorption of the porous cell structure to measure the sticking amount.
