USE OF ZEOLITE-BASED CATALYST FOR CONVERTING OXYGEN-CONTAINING COMPOUNDS TO LOWER OLEFINS, AS WELL AS METHOD OF PRODUCING LOWER OLEFINS Russian patent published in 2011 - IPC C07C1/20 B01J29/40 B01J29/48 B01J23/745 C07C11/02 B01J29/42 B01J23/83 B01J21/06 

FIELD: chemistry.

SUBSTANCE: described is use of a catalyst based on crystalline aluminium silicates, which is characterised by molar ratio SiO₂/Al₂O₃ between 20 and 200 and modified with (i) 0.1-10 wt % easily oxidisable metal (in terms of the corresponding metal oxide) and 0.05-5 wt % cerium in terms of Ce₂O₃, where the easily oxidisable metal used is iron (Fe) in terms of Fe₂O₃, or (ii) 0.05-5 wt % cerium in terms of Ce₂O₃, in order to convert oxygen-containing compounds to lower olefins. Described also is a method for catalytic production of lower olefins from oxygen-containing compounds using the catalyst described above as educts with high concentration of water vapour, provided that the molar ratio of water to the oxygen-containing compound in the reaction is between 0.5 and 10.

EFFECT: use of catalysts to convert oxygen-containing compounds to lower olefins.
