Title:
CATALYST SYSTEM FOR OXIDATIVE DEHYDROGENATION REACTION, REACTOR FOR BUTADIENE PRODUCTION INCLUDING SAME, AND METHOD FOR PREPARING 1,3-BUTADIENE
Document Type and Number:
WIPO Patent Application WO/2019/107884
Kind Code:
A1
Abstract:
The present invention relates to a catalyst system for an oxidative dehydrogenation reaction, a reactor for butadiene production including the same, and a method for preparing 1,3-butadiene. More specifically, the present invention relates to a catalyst system for an oxidative dehydrogenation reaction, etc., in which a coating catalyst is diluted and filled with a specific dilution filler in a reactor or is gradually filled in such a manner that the concentration of the active component of a catalyst for an oxidative dehydrogenation reaction is gradually increased from the direction in which a reactant is introduced, thereby effectively controlling heat generation inside the reactor to markedly improve a conversion rate, selectivity, yield, etc., and to enhance the long-term stability of a catalyst.
