Title:

BISMUTH MOLYBDATE-BASED CATALYST HAVING ZEOLITE COATING LAYER, METHOD FOR PRODUCING SAME, AND METHOD FOR PREPARING 1,3-BUTADIENE USING SAME

Document Type and Number:

WIPO Patent Application WO/2015/072820

Kind Code:

A1

Abstract:

The present invention relates to a bismuth molybdate-based composite oxide catalyst having high selectivity to 1,3-butadiene and comprising a microporous zeolite coating layer formed on a surface thereof, a method for producing the same, and a method for preparing 1,3-butadiene using the same. The catalyst has the zeolite coating layer with micropores, thereby selectively passing only a gas product (light) containing 1,3-butadiene, as a target product, thus improving the selectivity to 1,3-butadiene.
