FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing ethylene on modified aluminium oxide catalysts during dehydration of ethanol. Described is a catalyst for producing ethylene during dehydration of ethanol, containing aluminium oxide and chlorine in amount of 1.0-4.0 wt %. Described is a method of producing the catalyst by saturating aluminium oxide with hydrochloric acid, followed by drying and calcination, thereby obtaining a catalyst containing aluminium oxide and chlorine in amount of 1.0-4.0 wt % with specific surface of 150-300 m2/g and pore size distribution of 3-30 nm. Described is a method of producing ethylene via dehydration of ethanol using the catalyst described above at 350-400°C and contact time of 0.3-1 s.
EFFECT: high activity and selectivity of producing ethylene from ethanol.
