A number of bismuth molybdate catalysts, including pure bismuth molybdates (α-Bi2Mo3O12, β-Bi2Mo2O9, and γ-Bi2MoO6) and multicomponent bismuth molybdates, were prepared by a co-precipitation method for use in the production of 1,3-butadiene from C4 raffinate-3 through oxidative dehydrogenation of n-butene. Various experimental tools such as TPRO, XPS, and O2-TPD measurements were carried out to determine the oxygen mobility of bismuth molybdate catalysts. It was revealed that oxygen mobility of bismuth molybdate catalyst played a key role in determining the catalytic performance in the oxidative dehydrogenation of n-butene to 1,3-butadiene (The authors would like to acknowledge funding from the SK Energy Corporation). |
