Abstract

Катализатор, състоящ се от благороден метал, носител и в даден случай от прибавки, характеризиращ се с това, че включва: бедна на благороден метал или несъдържаща благороден метал; обемна периферна зона; богата на благороден метал обемна околовръстна зона и бедно на благороден метал или не съдържащо благороден метал ядро. Метод за получаване на катализатора, характеризиращ се с това, че носителят се импрегнира с разтвор на поне една сол на благороден метал, така че носителят да абсорбира разтвора; носителят и абсорбираният разтвор се изсушават; към изсушения носител се прибавя алкален разтвор в такова количество, че този разтвор да се абсорбира, при което солите на благородните метали се превръщат в неразтворими съединения и полученият след това воден екстракт има рн-стойност над 7 и носителят се обработва с редуциращо средство, за да се превърне неразтворимото съединение на благородния метал в съответния благороден метал. Приложение на катализатора в реакции, при които обикновено се влагат катализатори носители, съдържащи благородни метали. Патентните претенции са формулирани в 24 точкиA catalyst consisting of a noble metal, a carrier and, in some cases, additives, characterized in that it includes: poor in noble metal or no noble metal; volume peripheral zone; a noble metal rich bulk rim and a noble metal poor or no noble metal core. A method for preparing the catalyst, characterized in that the support is impregnated with a solution of at least one noble metal salt so that the support absorbs the solution; the carrier and the absorbed solution are dried; an alkaline solution is added to the dried support in such an amount that this solution is absorbed, whereby the noble metal salts are converted into insoluble compounds and the resulting aqueous extract then has a pH above 7, and the support is treated with a reducing agent to to convert the insoluble noble metal compound into the corresponding noble metal. Application of the catalyst in reactions in which supported catalysts containing noble metals are usually employed. The patent claims are formulated in 24 points
