METHOD OF PREPARING ALKYLBENZENE DEHYDROGENATION CATALYSTS Russian patent published in 1998 - IPC

Abstract RU 2114695 C1

FIELD: catalysts for petrochemical syntheses. SUBSTANCE: as iron oxide-based catalyst, exhausted catalyst is used after treatment with water in weight ratio 1:(0.12-0.20) at 20-30 C for 5-10 h followed by adding missing promoting additives and finally agitating mixture in presence of 1.6 to 2 weight parts of carbon dioxide per 1 part of catalyst. EFFECT: completely reused exhausted catalyst and avoided formation of waste water and loss of promoter. 1 tbl
