TANTALA-BASED COMPLEX METAL OXIDE SUPPORTED ON SILICA-BASED CATALYSTS FOR THE PRODUCTION OF 1,3-BUTADIENE FROM ETHANOL AND PRODUCTION METHOD OF 1,3-BUTADIENE USING THEREOF

摘要

The present invention relates to a catalyst for manufacturing 1,3- butadiene supported with a first metal oxide and a second metal oxide in silica, wherein the first metal oxide is a tantalum oxide and the second metal oxide is at least one selected from a group consisting of cerium oxide, nickel oxide, zirconium oxide and manganese oxide; and a manufacturing method for 1,3- butadiene using the same. Specifically, the catalyst of the present invention is practically applicable to a fixed bed reactor by selecting a silica mold carrier having an appropriate size and strength; impregnates tantalum oxide as the first metal oxide and cerium oxide, nickel oxide, zirconium oxide and manganese oxide as the second metal oxide; inhibits an occurrence of deactivation by minimizing the selectivity degradation of 1,3-butadiene as reaction time passes, which significantly improves the life expectancy of the catalyst as compared to an existing silica-based catalyst, thereby capable of being effectively used for the manufacture of 1,3-butadiene.
