摘要
The Al2O3 carrier material from Ag/Al2O3 supported catalysts which is obtained after the silver has been removed from such spent catalysts in a conventional manner is regenerated by a method in which the carrier material (a) is treated with an aqueous solution of a water-soluble salt or hydroxide of a metal of group IIA, IIIB or IVB of the Periodic Table or of aluminum, copper, manganese, zinc, cadmium, tin or lead, and the material treated in this manner is then dried, and/or the material (b) is heated at 750-1,500 DEG C. for not less than 10 minutes.
