COPPER-SUBSTITUTED ZIRCONIUM-PHOSPHATE - NEW OXIDATION CATALYST Academic Article uri icon

abstract

  • A novel catalytically active compound is obtained by substitution of copper cations into crystalline alpha -zirconium phosphate. Catalytic oxidation of carbon monoxide on crystalline copper-substituted zirconium phosphate was studied at different gas compositions, flow rates, and temperatures up to 400 C. A 1-ft long, tubular reactor with a preheater section is used for analysis. The rate of reaction is proportional to the square root of the carbon monoxide concentration. Oxygen, when present in large excess over its stoichiometric ratio, has no influence on the reaction rate. The apparent activation energy of 12. 5 kcal/mole and the rate constant for the reaction are determined. Results indicate that copper-substituted alpha -zirconium phosphate is comparable in activity with a number of active catalysts for carbon monoxide oxidation.
