Abstract: A process for the selective hydrogenation of aliphatic or aromatic substrates under supercritical or near critical conditions. Hydrogenation is effected using a heterogeneous catalyst in a continuous flow reactor containing a supercritical or near critical reaction medium and selectively product formation is achieved by varying one or more of the temperature, pressure, catalyst and flow rate.

Abstract: Production of a metal composite membrane consisting of a thin metal membrane having a required thickness and a metallic membrane support having a porous structure comprises placing a precursor of the metal membrane on a porous precursor of the membrane support; forming a metal composite between both precursors; adjusting the thickness of the metal membrane by deforming the metal composite; and producing the porous structure of the membrane support. Preferred Features: The metal composite is processed by cladding by rolling, explosive cladding or diffusion welding. The metal composite is deformed by rolling, pressing, hot extruding and/or deep drawing, preferably drawing into tubes. The membrane support has a thickness of less than 20-100, preferably 20-50 microns. The metal membrane has a thickness of 1-20, preferably 1-5 microns.

Abstract: A method for conversion of carbon monoxide to carbon dioxide and hydrogen with water in a gas mixture containing hydrogen and other oxidizable components. An oxidation-active noble metal shift catalyst is the catalyst. The necessary operating temperature of the catalyst is established and optionally maintained by partial oxidation of the oxidizable components of the gas mixture.

Abstract: A process for the alkylation of aromatic substrates under supercritical or near-critical reaction conditions is described. In particular, a method for performing Friedel-Crafts alkylation reactions is disclosed under those conditions. Friedel-Crafts reactions may be effected using a heterogeneous catalyst in a continuous flow reactor containing a supercritical or near-critical reaction medium. Selectivity of product formation can be achieved by varying one or more of temperature, pressure, catalyst, flow rates and also by varying the ratios of aromatic substrate to alkylating agent.
