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.
