REGULAR MESOPOROUS SILICA-BASED CATALYST FOR PREPARING 1,3-BUTADIENE FROM ETHANOL, AND METHOD FOR PREPARING 1,3-BUTADIENE USING SAME

摘要

The present invention relates to a catalyst for preparing 1,3-butadiene in which a transition metal compound is supported on regular mesoporous silica, and a method for preparing 1,3-butadiene using the same. Specifically, the catalyst of the present invention can improve the selectivity by optimizing the type and characteristics of the silica and specifying the type and content of a transition metal oxide, and to increase the yield of 1,3-butadiene by highly dispersed active sites due to a high surface area, and by having the regular mesoporous structure, diffusion of a reactant and a product and the transfer of materials is facilitated. In addition, since all of the active sites are not concentrated so as to be able to equally and uniformly participate in a reaction, the deterioration of activity is inhibited compared with a conventional silica catalyst in which micropores and mesopores coexist, thereby remarkably improving the lifetime of the catalyst compared with a conventional silica-based catalyst, and thus process operation efficiency can be improved due to a longer recycling period. Therefore, the catalyst of the present invention can be useful for preparing 1,3-butadiene.
