Abstract

Inventia se refera la un catalizator de argint pe suport, pentru fabricarea oxidului de etilena, preparat printr-un proces constînd din impregnarea unui suport catalitic poros cu un solvent continînd o sare de argint si tratarea suportului impregnat pentru determinarea depunerii argintului pe suprafata suportului. dup depunerea argintului, suportul este impregnat cu un lichid continînd mai mult de 30% în volum un solvent organic capabil sa formeze un complex cu ionul de argint, si un compus cu cel putin un promotor metalic pe suportul respectiv. Suportul impregnat este apoi tratat pentru determinarea depunerii de promotor. Se descrie de asemenea, în inventie un proces de fabricare a unui asemenea catalizator si un procedeu pentru producerea oxidului de etilena utilizînd catalizatorul.
