Abstract
Inventia se refera la un procedeu de preparare a unui catalizator continînd oxid de cupru, oxid de zinc, oxid de aluminiu si oxid de crom pentru conversia oxidului de carbon. Scopul inventiei este sa produca un catalizator ce se distinge printr-o activitate catalitica mare si un timp de exploatare îndelungat. Afara de aceasta la o activitate catalitica buna are o sensibilitate, scazuta fata de compusii clorului. Catalizatorul se prepara prin aceea ca într-o solutie apoasa care contine acid azotic, nitrat de cupru, nitrat de zinc si nitrat de aluminiu se dizolva o zaharida cu formula C12N22O11 si la aceasta se mai adauga un compus de crom (VI) si, în continuare din solutia care a luat nastere se precipita hidroxizii metalici cu ajutorul unei silitii apoase de hidroxid de sodiu, precipitatul se filtreaza, se spala, se usuca, se calcineaza si se formeaza în tablete. Raportul molar crom (VI) fata de dizahidra este de 0,26...0,36. Catalizatorul preparat se întrebuinteaza pentru conversia oxidului de carbon la temperaturi scazute.The invention relates to a process for the preparation of a catalyst comprising copper oxide, zinc oxide, aluminum oxide and chromium oxide for the conversion of carbon monoxide. The purpose of the invention is to produce a catalyst which is distinguished by a high catalytic activity and a long service life. Out of this, a good catalytic activity has a low sensitivity to chlorine compounds. The catalyst is prepared by dissolving a saccharide of formula C12N22O11 in an aqueous solution containing nitric acid, copper nitrate, zinc nitrate and aluminum nitrate, and chromium (VI) compound is added thereto, and From the resulting solution, the metal hydroxides precipitate with an aqueous sodium hydroxide silicate, the precipitate is filtered, washed, dried, calcined and formed into tablets. The chromium (VI) molar ratio to dizahydrate is 0.26-0.36. The prepared catalyst is used to convert carbon dioxide to low temperatures.
