Definitions
- the present disclosure relates to a catalyst composition for an oxidative dehydrogenation reaction and a method for preparing the same, and more particularly, excellent mechanical durability to prevent loss during a filling process and abrasion due to long-term use, and to form polymers and carbon during the reaction. Deposition is suppressed, and relates to a catalyst composition for oxidative dehydrogenation reaction having excellent conversion and selectivity, a method for preparing the same, and the like.
- oxidative dehydrogenation of butene occurs at 300 to 450 ° C. as a chemical process for preparing butadiene, a raw material for synthetic rubber. At this time, oxygen or water is added as an oxidizing agent, or butadiene is prepared using only butene.
- metal oxide catalysts such as molybdenum, bismuth, and cobalt, which are catalysts for oxidative dehydrogenation of butene, are manufactured into pellets through manufacturing and molding processes. Wear occurs. In particular, various problems occur, such as forming a metal oxide precursor and then pelleting in the process of firing.
- the present substrate is excellent in mechanical durability to prevent the loss during the filling process and abrasion due to long-term use, polymer formation and carbon deposition during the reaction is suppressed, conversion and selection
- An object of the present invention is to provide an excellent catalyst composition, a method for preparing the same, and a binder applied thereto.
- the present disclosure provides a catalyst composition comprising a multicomponent metal oxide catalyst and a mixed metal hydroxide.
