    Abstract: PROBLEM TO BE SOLVED: To enhance catalyst activity to catalyst volume by using a catalyst produced by precipitating and settling a solution of a particular zinc salt and an aluminum salt, separating precipitates by filtering, washing the precipitates, removing alkali metal ions and then drying and baking the precipitates to obtain mixed oxides. SOLUTION: A solution of a zinc salt and an aluminum salt having atomic ratio of Zn to Al of 3:1 to 1:3 is allowed to precipitate and settle at a pH value of 5-12 at a temperature of 20-100 deg.C by an alkali metal carbonate solution. Precipitates are separated by filtering and alkali metal ions are removed the precipitates are baked at 250-800 deg.C to obtain mixed oxides as a catalyst. The mixed oxides are dispersed in an acid solution of a copper salt and a zinc salt wherein atomic ratio of Cu to Zn is 1:5 to 20:1 and a dispersion solution is allowed to precipitate and settle at a pH value of 6-9 at a temperature of 20-100 deg.C so as to make methanol undergo steam reforming.

    Abstract: Noble metal catalyst, in particular platinum catalysts, which are applied on carriers and have become poisoned by metals as a result of being used for many years in the preparation of hydroxyl-ammonium salts by catalytic reduction of nitric oxide with hydrogen in an aqueous mineral acid are regenerated by a process in which the metallic impurities are dissolved using nitric acid or aqua regia, the solution is neutralized, the troublesome metals are precipitated from the neutralized solution by means of a selective precipitating reagent, and the purified platinum solution is reused for the preparation of the catalyst. Organic complexing agents which form insoluble or sparingly soluble complexes with the metallic impurities are preferably used as precipitating reagents.
