STUDY ON DEACTIVATION AND REGENERATION OF Pd/Al2O3 CATALYST IN HYDROGEN PEROXIDE PRODUCTION BY THE ANTHRAQUINONE PROCESS
Akad，-0001，（）：
Deactivated palladium catalysts in the hydrogenation of anthraquinone were regenerated with ethanol, nitric acid, hydrogen peroxide, boiling water and steam, respectively. The deactivated and regenerated catalysts were characterized by XPS, ICP, TG, FTIR, TPD, XRD, etc., and studied in the hydrogenation of anthraquinone. The results showed that the main cause of catalyst deactivation is the coverage of the active component by deposits. The treatments by hydrogen peroxide and boiling water can effectively regenerate the deactivated catalysts.Anthraquinone route, palladium catalyst, deactivation, regeneration
