Abstract: Catalyst for steam reforming alcohols contains a palladium/zinc alloy and zinc oxide as the catalytically active component deposited on a support made of aluminum oxide, aluminum silicate, titanium oxide and/or zeolites. An Independent claim is also included for a process for the production of an alloyed catalyst comprising dipsersing zinc oxide, titanium oxide and/or zeolites in water, adding an acidic solution of a palladium compound to the basic dispersion formed, neutralizing with a base, reducing using an aqueous reductant, filtering, washing, drying, calcining at 300-550 degrees C in an oxidizing atmosphere and reducing at 350-500 degrees C in a hydrogen-containing gas.

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.

Abstract: In converting carbon monoxide (CO) in a gas mixture containing hydrogen (H2) and other oxidizable constituents with water to carbon dioxide (CO2) and H2 (CO conversion) by passing the mixture over a shift catalyst at the CO conversion temperature, an oxidation-active shift catalyst based on noble metals is used and the operating temperature is adjusted and optionally maintained by partial oxidation of the oxidizable constituents of the gas mixture. An Independent claim is also included for a catalyst for this process, which comprises platinum and/or palladium, iron or copper and cerium oxide on a finely-divided alumina, in the form of a coating on a monolithic ceramic or metal honeycomb, open-cell ceramic or metal foam molding, metal sheet, heat exchanger plates or irregular molding.
