Abstract

Process for the reduction and safe disposal of a hexavalent chromium oxide based catalyst comprising contacting, under mixing conditions, a hexavalent chromium oxide based catalyst, with a molar excess, in respect of the chromium species, of a solid reducing agent and subjecting the mixture to a temperature in the range 30-1000C°. The process in simple, involves low costs and allows to obtain a permanently reduced chromium catalyst that can be disposed without toxicity risks. The disclosed reducing agents are FeS, FeSO4, Cu (O), carbon, hydroquinone and carbohydrats, preferably sucrose.
