Abstract: A process for depositing a noble metal catalyst on an oxide support material comprising contacting the support material with an alkaline solution of complex noble metal-amine cations under prescribed pH conditions is disclosed. The process is particularly suitable for depositing catalysts on monolithic honeycomb support structures because the catalyst dispersions produced thereby are extremely uniform on the interior channel walls of the structure.

Abstract: A method for treating platinum or palladium catalyzed porous ceramic burning pads of the type used in flameless gas heating and lighting devices. Certain catalytic substances such as thorium, alumina and silica-alumina, as well as combinations of these materials when combined with platinum or palladium, afford improved catalysts for porous ceramic burning pads of the type described above. Pads so treated reduce the carbon monoxide emissions from devices using these pads.

Abstract: Production of a catalyst comprised of a fine-particulate carrier and palladium metal for the partial dehalogenation of di- and/or trichloracetic acids in the presence of hydrogen to produce monochloracetic acid, wherein the dry porous carrier is impregnated with a palladium salt solution and the palladium absorbed by the carrier is reduced to palladium metal with the use of a suitable reducing agent. More particularly the palladium metal is concentrated exclusively on the surface of the carrier by impregnating and partially saturating the dry, fineparticulate carrier with the pure palladium salt solvent; by continuing impregnation until complete saturation of the carrier so pretreated with the necessary quantity of palladium salt solution; and by reducing the palladium salt applied to the carrier to palladium in known manner.
