CATALYST FOR PRODUCING BUTADIENE BY CONVERTING ETHANOL Russian patent published in 2014 - IPC B01J21/14 B01J21/12 B01J23/06 B01J23/02 B01J21/06 B01J23/14 C07C11/167 C07C1/20 

FIELD: chemistry.

SUBSTANCE: invention relates to methods of producing catalysts for the butadiene synthesis process. Described is a catalyst for producing butadiene by converting ethanol, which contains zinc, silicon, magnesium and aluminium compounds. The catalyst further contains calcium and/or strontium compounds. The composition of the catalyst, including oxides, is as follows, wt%: magnesium oxide 47-76, aluminium oxide 4.5-12.5, zinc oxide 0.1-1.5, calcium oxide and/or strontium oxide 1.5-7.5, silicon dioxide - the balance. The catalyst may contain oxides and/or compounds of barium and/or titanium and/or tin, which are easily decomposed to oxides, in amount of 0.5-5.0 wt% and/or portland cement in amount of 1-20 wt%.

EFFECT: high conversion of ethanol and butadiene selectivity.
