Abstract:
Multicomponent bismuth molybdates were prepared by a co-precipitation method for use in the oxidative dehydrogenation of n-butene to 1,3-butadiene. The effect of divalent and trivalent metals on the catalytic performance of multicomponent bismuth molybdate catalysts was investigated. It was found that the metal ratio of Fe/Bi/Mo = 3:1:12 was favorable for the reaction. The successful formation of NiXCo8−XFe3Bi1Mo12O50 (X = 0-8) catalysts was well confirmed by XRD and ICP-AES measurements. The multicomponent bismuth molybdate catalysts showed a better catalytic performance than the pure γ-Bi2MoO6 catalyst. Among the NiXCo8-XFe3Bi1Mo12O50 (X = 0-8) catalysts, Ni3Co5Fe3Bi1Mo12O50 showed the highest yield of 1,3-butadiene.Keywords: MULTICOMPONENT BISMUTH MOLYBDATE; N-BUTENE; 1,3-BUTADIENE; OXIDATIVE DEHYDROGENATION
