摘要

1. A method of processing catalytically active molded products, which includes the following process steps: a) preparing final prepared catalytically active molded products, b) impregnating these final prepared catalytically active molded products with a peptizing aid in an amount of liquid that does not exceed the theoretical moisture absorption of these catalytically active molded products, c) heat treatment of impregnated catalytically active molded products at a pace Aturi from 50 ° C to 250 ° C and d) calcining the thermally treated these catalytically active molded articles at a temperature of 250 ° C to 600 ° C.2. The method according to claim 1, wherein an ammonia solution or a solution of nitric acid, in particular aqueous ammonia or an aqueous solution of nitric acid, is used as a peptizing aid. The method according to claim 1, wherein after the process step b), the process step bb) is carried out allowing exposure to the peptizing aid for up to 10 hours. The method according to claim 1, wherein the heat treatment in process step c) is carried out at normal pressure or in vacuum, preferably from 0.1 to 0.9 bar, and / or in a fixed or stirred bulk layer of catalytically active molded products.
