Abstract
A method of impregnating a catalytic component on a carrier material. The carrier material is immersed in an impregnating solution containing a catalytic component and a polybasic 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. Prior to calcining, the impregnated carrier material is further impregnated with an alkaline earth metal salt of an organic acid, and the solution evaporated to dryness in contact with the impregnated carrier material.
