MIXED METAL OXIDE CATALYSTS AND METHOD OF CATALYTIC CONVERSION OF LOWER ALIPHATIC HYDROCARBONS Russian patent published in 2013 - IPC B01J23/28 B01J23/22 B01J23/16 B01J21/06 B01J23/14 B01J23/10 B01J35/10 C07C253/24 C07C51/215 

FIELD: chemistry.

SUBSTANCE: claimed invention discloses catalytic compositions, which contain mixed metal oxides, which demonstrate activity in propane or isobutene conversion into unsaturated nitryl by ammoxidation in presence of ammonia and oxygen source. Composition includes one or more crystalline phases, at least, one of which is first phase, characterised by crystalline structure MI and including mixed metal oxide, which contains molybdenum (Mo), vanadium (V), antimony (Sb) and niobium (Nb). First phase has volume of elementary cell, which lies within the range towards increase from 2255 A³ to 2290 A³, first dimension of crystal and transverse to it second dimension, on condition that ratio of first dimension to second dimension is within the range towards reduction from 1.75 to 1.0 (aspect ratio). In particular, mixed oxide material isd represented by empirical formula MoV_aSb_bNb_cO_δ; where 0.1<a<1.0, 0.01<b<1.0, 0.001<c<0.25, and δ represents number of oxygen atoms, which are required for preservation of electric neutrality of other present constituting elements. Also described is method of ammoxidation in presence of ammonia and oxygen source by means of said disperse hard catalyst.

EFFECT: ensuring high output.
