1. A method of preparing butadiene comprising:

  • (a) providing an alcohol mixture comprising one or more butanols;

    (b) contacting said alcohol mixture with a dehydration catalyst, thereby forming an olefin mixture comprising one or more linear butenes and isobutene;

    (c) contacting the olefin mixture of (b) with a dehydrogenation catalyst, thereby forming a di-olefin mixture comprising butadiene and isobutene; and
