ABSTRACT:
A method of impregnating a catalytic component as a subsurface layer on a carrier material. The carrier material is immersed in an impregnating solution containing a catalytic component and a dibasic carboxylic acid, with a sulfur-containing carboxylic acid being subsequently added to the solution whereby the catalytic component is dispersed in a subsurface layer on the carrier material and penetration beyond the desired subsurface layer is substantially obviated.
