MESOPOROUS COMPLEX OXIDE CATALYST, METHOD FOR PREPARING THE CATALYST, AND METHOD FOR PREPARING 1,3-BUTADIENE USING THEREOF

摘要

The present invention relates to a mesoporous complex oxide catalyst; to a manufacturing method of the mesoporous complex oxide catalyst; and to a synthesis method of 1,3-butadiene using the mesoporous complex oxide catalyst. According to the present invention, mesoporous silica is used in a manufacturing process of a catalyst for synthesis of 1,3-butadiene. Therefore, the mesoporous complex oxide catalyst improves the conversion ratio of n-butene and the selectivity and yields of 1,3-butadiene due to enhancement of surface area, and also can offer economic efficiency capable of lowering catalyst production costs by reducing the amount of metal used. The mesoporous complex oxide catalyst is represented by chemical formula 1: (x%)MoaBibFecCodEeOy+(100-x)%SiO_2 and has pores, wherein the pores have an average pore volume of 0.01-2 cm^3/g and an average pore size of 2-50 nm.
