Description
Dotychczasowe sposoby otrzymania ka¬ talizatorów zelaznych z chromem posluguja sie metoda stracania chromu ze soli chro¬ mu zapomoca alkaljów lub amonjaku lub tez dodaja do osadu tlenku lub wodorotlen¬ ku zelaza sole kwasu chromowego, np. chromian lub dwuchromian potasu. Przed¬ miotem niniejszego wynalazku jest otrzy¬ manie katalizatora, zawierajacego obok ze¬ laza chrom w specjalnie aktywnej postaci, znacznie przewyzszajacej aktywnoscia ka¬ talizatory znane o podobnym skladzie.Jako materjalu wyjsciowego uzywamy zwiazków zelaza dwuwartosciowego oraz kwasu chromowego; w wyniku reakcji tych cial nastepuje redukcja kwasu chromowe¬ go, przyczem zelazo dwuwartosciowe utle¬ nia isie na wyzszy stopien. Mozna otrzymy¬ wac na tej drodze katalizatory, zawieraja¬ ce obok zelaza i chromu tez inne skladniki, które mozna dodawac w róznych stadjach produkcji.Przyklad. 100 kg zelaza rozpuszcza sie w rozcienczonym kwasie azotowym, dodaje 10 kg kwasu chromowego lub 20 kg chro¬ mianu potasu i w temperaturze 60° sitra- ca sie amonjakiem. Cala ilosc chromu prze¬ chodzi do osadu.*) Wlascicielka patentu oswiadczyla, ze wynalazca jest p. Godlewicz w Królewskiej Hucie. PLHitherto methods of obtaining iron catalysts with chromium use the method of removing chromium from the chromium salt by means of alkali or ammonia, or by adding to the precipitate iron oxide or hydroxide salts of chromic acid, for example potassium chromate or dichromate. The object of the present invention is to obtain a catalyst containing, in addition to iron, chromium in a specially active form, significantly exceeding the activity of known catalysts of similar composition. We use divalent iron compounds and chromic acid as a starting material; as a result of the reaction of these bodies, the chromic acid is reduced, with the oxidation of divalent iron and the increase to a higher degree. In this way, it is possible to obtain catalysts containing, in addition to iron and chromium, also other ingredients, which can be added at various stages of production. 100 kg of iron are dissolved in dilute nitric acid, 10 kg of chromic acid or 20 kg of potassium chloride are added and the temperature is 60 ° filtered with ammonia. All the chromium goes to the sediment. *) The owner of the patent stated that the inventor was Mr. Godlewicz in Królewska Huta. PL
