Process for the redn. 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 mixt. to a temp. in the range 30-1000 °C. The process in simple, involves low costs and allows to obtain a permanently reduced chromium catalyst that can be disposed without toxicity risks.

Abstract

Process for the redn. 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 mixt. to a temp. in the range 30-1000 °C. The process in simple, involves low costs and allows to obtain a permanently reduced chromium catalyst that can be disposed without toxicity risks.
