摘要： A method for isomeris ng dehydration in the presence of a specific catalyst, to produce at least one alkene, carried out on a feedstock containing a non-linear primary monoalcohol, where the catalyst includes a zeolite having a series of 8MR channels and a binder having certain pore volume, which catalyst is multilobe-shaped and has characteristics including certain average mesopore volume Vm, and mesopores having a certain diameter, an average certain macropore volume VM, the macropores having a certain diameter, and certain average micropore volume Vμ, the micropores having a certain diameter, and the catalyst has a certain exposed geometric area.

摘要： A process for the isomerizing dehydration of a feedstock including a primary monoalcohol, alone or as a mixture, of formula R—CH2—OH, wherein R is a nonlinear alkyl radical of general formula CnH2n+1 where n is an integer between 3 and 20, the process taking place in the gas phase at a weighted average temperature between 275° C. and 400° C., at a pressure between 0.3 MPa and 1 MPa and at a WWH (weight per weight per hour) between 5 and 10 h−1, in the presence of a catalyst containing at least one silicic binder and at least one zeolite having at least one series of channels, the opening of which is defined by a ring of 8 oxygen atoms (8MR), process wherein vaporized feedstock entering the reactor has a weight content of water of from 4% to 35%.
