ABSTRACT:
A body made up of substantially continuous high strength multicellular support having porous cell walls, and pores in the cell walls having an average pore diameter of which have active material embedded therein, and an outer surface. The body is made of material which can be ceramics, glass, glass-ceramic, cermet, metal, oxides, and combinations of these. The active material can be molecular sieve, activated carbon, and combinations these. A method for producing a pore-impregnated body which involves providing the substrate having a wall porosity greater than about 45% by volume, and an average pore diameter of about 15 to 30 micrometers, providing a slurry of active material dispersed in a medium, contacting the support with the slurry at subatmospheric pressure to substantially fill the open pores of the substrate with the active material, removing excess slurry from the outer surface and the non-pore surfaces of the cell walls, followed by drying.
