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, 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.
