“…Various bismuth molybdate catalysts, including pure bismuth molybdates (a-Bi 2 Mo 3 O 12 , b-Bi 2 Mo 2 O 9 , and c-Bi 2 MoO 6 ) and multicomponent bismuth molybdates, were prepared by a co-precipitation method for use in the production of 1,3-butadiene from C 4 raffinate-3 through oxidative dehydrogenation of n-butene [29][30][31][32]. Oxygen mobility of bismuth molybdate catalysts was determined by TPRO (temperature-programmed reoxidation) [33], XPS (X-ray photoelectron spectroscopy) [34], and O 2 -TPD (temperature-programmed desorption) measurements [35].…”

“…It has been reported that the reactivity of n-butene isomers strongly depends on the catalyst system in the oxidative dehydrogenation of n-butene [29]. Our preliminary investigations also revealed that the reactivity of n-butene isomers over ZnFe 2 catalyst was also prepared by a coprecipitation method.…”

Oxidative Dehydrogenation of C4 Raffinate-3 to 1,3-Butadiene in a Dual-bed Reaction System Comprising ZnFe2O4 and Co9Fe3Bi1Mo12O51 Catalysts: A Synergistic Effect of ZnFe2O4 and Co9Fe3Bi1Mo12O51 Catalysts

Oxidative dehydrogenation of C 4 raffinate-3 to 1,3-butadiene was carried out in a dual-bed reaction system comprising ZnFe 2 O 4 and Co 9 Fe 3 Bi 1 Mo 12 O 51 catalysts in order to investigate a synergistic effect of these two catalysts. Conversion of n-butene and yield for 1,3-butiadene obtained in a dual-bed reaction system comprising ZnFe 2 O 4 (first-bed) and Co 9 Fe 3 Bi 1 Mo 12 O 51 (second-bed) were higher than those obtained in a single-bed reaction system using either ZnFe 2 O 4 or Co 9 Fe 3 Bi 1 Mo 12 O 51 . 1-Butene-TPD and 2-butene-TPD measurements revealed that ZnFe 2 O 4 catalyst retained more selective oxygen species for the reaction with 2-butene than for the reaction with 1-butene, while Co 9 Fe 3 Bi 1 Mo 12 O 51 catalyst retained more selective oxygen species for the reaction with 1-butene than for the reaction with 2-butene. The synergistic effect of ZnFe 2 O 4 (first-bed) and Co 9 Fe 3 Bi 1 Mo 12 O 51 (second-bed) catalysts in the oxidative dehydrogenation of C 4 raffinate-3 was attributed to the combination of high catalytic activity of ZnFe 2 O 4 for 2-butene and high catalytic activity of Co 9 Fe 3 Bi 1 Mo 12 O 51 for 1-butene.

“…It was observed in our previous work [26] that c-Bi 2 MoO 6 showed the best catalytic performance in the oxidative dehydrogenation of n-butene, among three types of pure bismuth molybdates (a-Bi 2 Mo 3 O 12 , b-Bi 2 Mo 2 O 9 , and c-Bi 2 MoO 6 ). It is known that the fundamental structure of multicomponent bismuth molybdate catalysts is composed of four elements including divalent metal (M II ), trivalent metal (M III ), bismuth, and molybdenum [17,24].…”

Pure bismuth molybdate (c-Bi 2 MoO 6 ) and multicomponent bismuth molybdate (Co 9 Fe 3 Bi 1 Mo 12 O 51 ) catalysts were prepared by a co-precipitation method, and were applied to the oxidative dehydrogenation of n-butene to 1,3-butadiene. The Co 9 Fe 3 Bi 1 Mo 12 O 51 catalyst showed a better catalytic performance than the c-Bi 2 MoO 6 catalyst in terms of conversion of n-butene and yield for 1,3-butadiene, indicating that the multicomponent bismuth molybdate was more efficient than the pure bismuth molybdate in the oxidative dehydrogenation of n-butene. It was revealed that the crucial factor determining the catalytic performance of Bi-Mo-based catalyst in the oxidative dehydrogenation of n-butene is not the amount of oxygen in the catalyst involved in the reaction (oxygen capacity) but the intrinsic mobility of oxygen in the catalyst involved in the reaction (oxygen mobility). The enhanced catalytic performance of Co 9 Fe 3 Bi 1 Mo 12 O 51 was due to its facile oxygen mobility.
