CATALYSEURS A BASE D'OXYCARBURE DE MOLYBDENE MODIFIE PREPARE A PARTIR D'OXYDE DE MOLYBDENE ORIENTE ET SON PROCEDE D'OBTENTION

摘要

The invention concerns a catalyst with modified molybdenum oxycarbide base having a specific surface area more than 5 m<2>/g and improved catalytic activity, in particular in velocity constant, characterised in that it is prepared from molybdenum oxide MoO3 with a structure essentially comprising preferentially oriented monocrystalline plates resulting from sublimation condensation. The invention also concerns a method for producing such a catalyst.
