摘要： A method of preparing a catalyst for oxidative dehydrogenation that includes coprecipitation and injecting inert gas or air at a specific time point to reduce the ratio of an inactive α-Fe2O3 crystal structure, thereby improving the activity of the catalyst. Also provided is a method of performing oxidative dehydrogenation using the catalyst. When oxidative dehydrogenation of butene is performed using the catalyst, side reaction may be reduced, and selectivity for butadiene may be improved, providing butadiene with high productivity.

摘要： Provided is a catalyst system for oxidative dehydrogenation, a reactor for oxidative dehydrogenation including the catalyst system, and a method of performing oxidative dehydrogenation using the reactor. In the catalyst system, a fixed-bed reactor is filled with a catalyst for oxidative dehydrogenation in an n-stage structure (n being an integer of 2 or more), wherein each stage of the n-stage structure satisfies Equations 1 and 2 as claimed so that the concentration of an active ingredient included in the catalyst gradually increases in the direction in which reactants are fed into the reactor. Heat generated inside the reactor may be effectively controlled during oxidative dehydrogenation, thereby improving conversion rate, selectivity, and yield. In addition, catalyst deterioration may be reduced, thereby improving long-term stability of the catalyst.

摘要： The present invention relates to a bismuth molybdate-based composite oxide catalyst having a microporous zeolite coating layer on the surface thereof and thus having high selectivity for 1,3-butadiene, a method of preparing the same, and a method of preparing 1,3-butadiene using the same. The catalyst has a microporous zeolite coating layer, and thus enables only gaseous products (light) to selectively pass through the zeolite coating layer, improving selectivity for 1,3-butadiene.
