Abstract

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.
