Effect of reaction conditions on the catalytic performance of Co9Fe3Bi1Mo12O51 in the oxidative dehydrogenation of n-butene to 1,3-butadiene
Jung JC, Lee HW, Park SY, Chung YM, Kim TJ, Lee SJ, Oh SH, Kim YS, Song IK
Oxidative dehydrogenation of n-butene to 1,3-butadiene over Co9Fe3Bi1Mo12O51 catalyst was conducted in a continuous flow fixed-bed reactor. The effect of reaction conditions (steam/n-butene ratio, reaction temperature, and space velocity) on the catalytic performance of Co9Fe3Bi1Mo12O51 was investigated. Steam played an important role in decreasing contact time, suppressing total oxidation of n-butene, and removing coke during the reaction. Yield for 1,3-butadiene showed a volcano-shaped curve with respect to steam/n-butene ratio. The compensation between thermodynamic effect and kinetic effect led to a volcano-shaped curve of 1,3-butadiene yield with respect to reaction temperature. The Co9Fe3Bi1Mo12O51 catalyst showed the best catalytic performance at a certain value of space velocity. The optimum steam/n-butene ratio, reaction temperature, and gas hourly space velocity were found to be 15, 420 ℃, and 675 h^(-1), respectively.
