Description

W latach ostatnich stosowanie katali¬ zatorów metalowych do hartowania kwa¬ sów tluszczowych i ich estrów przybralo znaczne rozmiary, przyczem katalizator}', przewaznie niklowe, byly preparowane w najrozmaitszy sposób. Zadaniem wiel¬ kiej wagi jest wytworzenie katalizatora w mozliwie najprostszej formie, a przy- tem o mozliwie najwyzszej sprawnosci.Próby wykazaly, ze gliniany ciezkich metalów, zwlaszcza niklu, daja kataliza¬ tory o wydatnem dzialaniu. Bardzo spraw¬ nie dzialajacy katalizator otrzymuje sie w nastepujacy prosty sposób.Z roztworów soli ciezkich metali, zwlaszcza soli niklowych, naprzyklad siar¬ czanu niklu straca sie przy miernej tem¬ peraturze rozpuszczalnemi glinianami, na¬ przyklad glinianem sodowym glinian niklowy, osad przemywa, suszy i traktuje wodorem przy 300—400°C.Niniejszy sposób otrzymywania kata¬ lizatora ma nastepujace zalety: wymaga stosunkowo drobnych ilosci niklu, prze¬ mywanie osadu latwo daje sie uskutecz¬ nic, nikiel rozdzielony jest w kataliza¬ torze na nadzwyczajnie drobne czasteczki, wreszcie, dzieki temu rozdrobnieniu, kata¬ lizator w czasie procesu hartowania ole¬ jów i tluszczów nie opada na dno, lecz pozostaje w zawieszeniu, wskutek czego dzialanie reakcyjne pomiedzy olejami, katalizatorem i wodorem jest bardzo ulatwione.Mozna takze obojetne ciala, jak na¬ przyklad krzemionke, przepoic roztworem soli niklowych, glinian niklu osadzic na powierzchni ciala obojetnego zapomocaa': glinianu sodowego i dalej stosowac jak wyzej. PL PLIn recent years, the use of metal catalysts for quenching fatty acids and their esters has become very large, and the catalysts, mostly nickel-based, have been prepared in a variety of ways. The task of great importance is to make the catalyst as simple as possible and at the same time as efficient as possible. Trials have shown that clay from heavy metals, especially nickel, produces catalysts with high performance. A very efficient catalyst can be obtained in the following simple way: From solutions of heavy metal salts, especially nickel salts, for example nickel sulphate, at moderate temperatures, are lost by soluble aluminates, for example sodium aluminate, nickel aluminate, sludge washed, dried and treated with hydrogen at 300-400 ° C. The present method of obtaining the catalyst has the following advantages: it requires relatively small amounts of nickel, washing the sludge is easily effective, the nickel is separated in the catalyst into extremely fine particles, and finally Due to this fragmentation, the catalyst does not sink to the bottom during the quenching process of oils and fats, but remains in suspension, as a result of which the reaction between oils, catalyst and hydrogen is greatly facilitated. Inert bodies, such as for example silica, permeate with a solution of nickel salts, deposit nickel aluminate on the surface of the inert body with a sodium aluminate and continue as above. PL PL
