Abstract: Carbon monoxide is removed from flows of material by means of adsorption to a adsorption mass containing copper, zinc, and zirconium.

Abstract: A methanol reforming catalyst containing passivated copper and zinc oxide and/or alumina can be prepared by (1) precipitating or spray-drying a mixture of catalyst precursor components dissolved or suspended in a diluent in order to form a solid catalyst precursor in the form of powder or granules, (2) calcining and reducing the solid catalyst precursor obtained in stage (1), (3) passivating the reduced catalyst precursor obtained in stage (2) and (4) shaping the passivated catalyst precursor obtained in stage (3) to form the catalyst. A reduction in the volume shrinkage and an increase in the mechanical hardness during operation of the methanol reforming catalyst are achieved by the preparation process.

Abstract: Hydrogenous gases are prepared by reacting hydrocarbons with air and/or water at temperatures of from 300 to 1000° C. and a pressure of from 1 to 20 bar in the presence of a catalyst by using a spinel catalyst which comprises at least one element of transition group VIII of the periodic table.
