Preparation and formation of nickel-copper catalytic systems on various supports and commercial catalysts based on these systems

Based on the Ni-Cu system, catalysts were developed for low-and high-temperature industrial gas and waste gas purification. It was found that, regardless of the preparation procedure, the formation of a catalytically active structure occurred via the formation of a Ni-Cu solid solution at the stage of activation. The catalytic, physicochemical, and physicomechanical properties of NKO Ni-Cu catalysts can be purposefully regulated by changing the nature and concentration of a liquid reagent. A promoting effect of copper on the activation process and on the catalytic activity of a nickel catalytic system was found. The catalysts developed were commercialized. The catalysts were introduced into various processes of industrial gas and waste gas purification.
