Study on the new hydrogenation catalyst and processes for hydrogen peroxide through anthraquinone route

The main process for industrial synthesis of hydrogen peroxide is to subject 2-ethylanthraquinone to cyclic hydrogenation and oxidation. Hydrogenation catalyst is one of the key techniques of anthraquinone route. A new egg-shell palladium catalyst with racshig-ring alumina supported was developed for meeting the mechanism and improving mass transformation based on the kinetics and mass transfer theory, the effects of materials feeding methods together with operating conditions on the hydrogenation efficiency were detailed. It was concluded that the egg-shell palladium catalyst developed by this research has higher hydrogenation efficiency than the commercial contrast catalysts.
