BISMUTH MOLYBDATE CATALYST HAVING ZEOLITE COATING LAYER, PREPARATION METHOD THEREOF AND METHOD OF PREPARING 1,3-BUTADIENE USING THE SAME

摘要

The present invention relates to a bismuth molybdate-based composite oxide catalyst having high selectivity to 1,3-butadiene and having a microporous zeolite coating layer formed on a surface thereof, a method for preparing 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.
