Abstract
There is disclosed an improved dehydrogenation catalysts prepared from mixtures of WO.sub.3 and V.sub.2 O.sub.5 ; mixtures of MoO.sub.3 and V.sub.2 O.sub.5 and mixtures of Cr.sub.2 O.sub.3 or CrO.sub.3 and V.sub.2 O.sub.5 which are heated to temperatures to melt the oxides to form W(VO.sub.4).sub.2, Mo(VO.sub.4).sub.2 and CrVO.sub.4 which are then treated with a reductant to form the active dehydrogenation catalytic species, the methods for the preparation of these catalysts and to the improved dehydrogenation processes which can be effected when dehydrogenatable hydrocarbons are in contact with these catalysts.
