Abstract
Demand for 1,3-Butadiene (BD) expected to
increase dramatically. Catalytic oxidative dehydrogenation (ODH) of 1-butene offers
an alternative route to produce BD.
Researchers employed a soft oxidant, CO2,
instead of O2. They selected Fe2O3 from a
preliminary screening using Temperature Programmed Surface Reaction (TPSR). They
observed that catalytic performance was greatly improved by supporting Fe2O3
on Al2O3. Results of their study demonstrate that both Fe2O3
and CO2 are involved in the reaction. The main byproducts,
trans/cis-2-butenes, can also be converted to BD with similar BD yield.
