Abstract: The activity and stability of copper chromite catalysts have been found to be sensitive to both copper-to-chromium ratio and to alumina content. Alumina-containing catalysts of improved stability for the oxidation of carbon monoxide at high temperatures and the use of these catalysts in the control of automotive exhaust emissions are described.

Abstract: This invention relates to the discovery of a method for incorporating various oxides into silica-containing porous and nonporous glass materials by dissolving soluble compounds of the additive oxides, characterized as MxOy, into solutions, colloidal solutions, or suspensions of soluble silicates, reacting the mixture with an organic compound, and then firing the thus-formed body at temperatures below the softening point of the particular glass composition for a sufficient length of time to produce the porous body or non-porous glass body containing the added oxides intimately bonded to the silica network.
