Abstract: Isomerizing dehydration of feedstock containing a primary alcohol substituted in position 2 by an alkyl group in which the feedstock is heated to the reaction temperature by indirect heat exchange then vaporization by mixing with a diluent effluent, the diluted and vaporized feedstock being dehydrated in at least one dehydration reactor operating in gas phase at an inlet temperature comprised between 250 and 375° C., at a pressure comprised between 0.2 MPa and 1 MPa and at a WHSV comprised between 1 and 18 h−1, in the presence of a catalyst comprising a zeolite having at least one series of channels the opening of which is defined by a ring with 8 oxygen atoms (8MR) and a binder, the catalyst being coked beforehand in-situ or ex-situ, so as to produce a dehydration effluent, the latter being treated and separated into a diluent effluent, an alkenes effluent and a heavy hydrocarbons effluent.

Abstract: 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; and an 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.
