Title: METHOD FOR PREPARING CATALYST FOR OXIDATIVE DEHYDROGENATION REACTION AND OXIDATIVE DEHYDROGENATION METHOD USING SAME CATALYST
Abstract:
The present invention relates to a method for preparing a catalyst for an oxidative dehydrogenation reaction and an oxidative dehydrogenation process using the same. More specifically, the present invention includes a process of supplying an inert gas or air at specific time when preparing a catalyst for an oxidative dehydrogenation reaction by co-precipitation, thereby reducing an inactive α-Fe2O3 crystal structure and improving the activity of the catalyst, and furthermore, the present invention applies the same to an oxidative dehydrogenation reaction of butene so as to suppress side reactions and improve the selectivity of butadiene, thereby providing a high productivity of butadiene.
