  • Patent number: 11389777
    Abstract: Reactors and methods of using the reactors to produce 1-butene are disclosed. A feed stream comprising n-butane is flowed to a dehydrogenation compartment of a reactor. The dehydrogenation compartment includes a dehydrogenation catalyst for catalyzing the dehydrogenation of n-butane to produce a dehydrogenation compartment effluent comprising 1-butene, 2-butene, isobutene, and/or unreacted n-butane. The dehydrogenation compartment effluent is flowed to a isomerization compartment of the reactor. The isomerization compartment contains a catalyst for isomerizing 2-butene in the dehydrogenation compartment effluent to produce 1-butene. A heating section is disposed between the dehydrogenation compartment and the isomerization compartment to provide heat for the reactions in both compartments.
