CATALYSEUR UTILISABLE EN HYDROTRAITEMENT COMPRENANT DES METAUX DES GROUPES VIII ET VIB SAUF LE COUPLE COBALT-MOLYBDENE, ET PREPARATION AVEC DE L'ACIDE ACETIQUE ET DU SUCCINATE DE DIALKYLE C1-C4

摘要

Catalyst (I) comprising amorphous support made of alumina, phosphorus, at least one 1-4C dialkyl succinate, acetic acid and hydro-dehydrogenating function consists of element of group VIB and at least one element of group VIII with the exception of the hydro-dehydrogenating function consists of cobalt and molybdenum, where Raman spectrum of the catalyst comprises bands of 990 and/or 974 cm -1>with Keggin heteropolyanion characteristics, characteristic bands of succinate and main bands of 896 cm -1>of acetic acid characteristics, is new. An independent claim is included for the preparation of (I).
