摘要
A process is disclosed for the regeneration, by thermal treatment, of used catalysts for a cyclical process for the production of hydrogen peroxide. According to the process, used aluminosilicate type catalyst is subjected to progressive heating up to a temperature between 700 DEG and 850 DEG C., in the presence of an oxidizing atmosphere circulating co-current to the catalyst being regenerated. The process can be carried out in a rotary furnace inclined to the horizontal by 0.7 to 1% and having radial fins on the lower section of its inner wall, and an adjustable diaphragm at its outlet.
