Abstract

See full text

Production of a mixture of ethylene and propylene from a mixture containing ethanol and isopropanol and having a water content between 30 and 75 wt. % is obtained by a process comprising:

    a) contacting the mixture in a dehydration unit with a dehydration catalyst chosen from: an alumina (A) having a BET specific surface area between 200 and 350 m2/g, a mean mesopore diameter between 5 and 15 nm, a sodium content of less than 50 ppm by weight, and a sulphur content of less than 40 ppm by weight; andan alumina (B) having a BET specific surface area between 130 and 180 m2/g, a mean mesopore diameter between 14 and 20 nm, a sodium content between 300 and 600 ppm by weight, and a sulphur content between 800 and 1300 ppm by weight; b) withdrawing an effluent containing ethylene and propylene from the dehydration unit.
