ABSTRACT:
The invention relates to a multi-layer catalyst made from niobium for the catalytic conversion of hydrocarbons, comprising a) a support component made from a doped or undoped oxide or hydroxide of an element of the V sub-group of the periodic table, or mixtures thereof, b) a layer of a promoter compound, selected from oxygen, sulphur or phosphorus compounds of an element of the VI, VII and VIII sub-group or a phosphoxy compound and mixtures thereof and c) a layer comprising a compound of platinum metal. The invention further relates to a method for production of the catalyst and the use thereof.
