摘要： A method of producing a catalytically active product (10) is disclosed. The method comprises providing a substrate (11) and depositing a first material (12) and particles (13) of a second material on the substrate, wherein the particles (13) of the second material have a higher melting point than the first material (12). Then, the substrate (11) with the first material (12) and said particles (13) is heated to a temperature where the first material (12) is melted and the particles (13) of the second material are not melted, wherein the first material (12) and the particles (13) are adhered to the substrate (11), wherein particles (13) are partly embedded in the first material (12) and form a rough surface. A ceramic material is deposited on the rough surface formed by the particles (13) to form a ceramic layer (14) thereon, wherein a catalytically active material (16) id added to the ceramic layer (14). Disclosed is also a catalytically active product.

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.
