Characterization and activity of V2O5/CeO2-MgO catalyst in the dehydrogenation of ethylbenzene to styrene
Nguyen VK, Park JH, Shin CH
Supported vanadia catalyst was impregnated on CeO2-MgO and characterized by N2 adsorption, XRD, XPS, TPR and solid NMR. The vanadia species dispersed well on the support surface with vanadia content up to 10 wt%. At higher vanadia content, the non-active Mg3(VO4)2 was formed. Vanadium oxides existing on the support surface as tetrahedral vanadium were observed. An ethylbenzene conversion of 43% and styrene selectivity of 91% were obtained with the 10V2O5/CeO2-MgO catalyst.
Keywords: Ethylbenzene; Dehydrogenation; Vanadia; Ceria; Magnesia
