Abstract: A layered catalyst support or carrier provides a core member for carrying out non-steady state heterogeneously catalyzed processes where reaction gases and their products come in contact with a conventional catalyst applied to the carrier. The support as a carrier is made up of a large number of individually shaped particulate bodies or monolithic packings to be loaded into a reactor and maintained as a fluidized bed or a fixed bed during the non-steady state reaction and the recovery of the products. The support or carrier may consist of glass, quartz, oxides, nitrides, aluminosilicates, magnesium silicates, metals and carbon or their mixtures. Each shaped particle or monolithic packing of this core support is then completely enclosed by depositing thereon a thin protective layer of a nitride, oxide, carbide or chloride of a metal, a non-metal or a mixture thereof, which exhibits a dense, pore-free microstructure and a nonpolar surface having a very low density of acid centers.

Abstract: A process for producing a polymer/metal or polymer/semiconductor composite having an adhesive layer between the polymer and the metal or between the polymer and the semiconductor in which a layer of at least two different chemical elements is applied to the metal or semiconductor by vapor-deposition or cathode sputtering, then selectively or partially removing at least one chemical element of this layer in an etching process, and then applying the polymer.
