Study about burning hydrogen isotopes on metallic catalyst

In some stage of the detritiation process the oxygen is considered as an impurity in the fluid, that could produce the obstruction of the pipes. The oxygen could be removed by recombination with hydrogen, using a metallic catalyst. The final product of the detritiation process is deuterated hydrogen. In the process of the catalytic burning of the deuterated hydrogen, the heavy water, free of tritium, is obtained witch could be reused in the CANDU reactor. The interaction between hydrogen and oxygen molecules devolves through a succession of reactions. Superficial species which are participating in the reaction, proceed from the dissociate chemisorption of the oxygen and the hydrogen molecules. The catalytic oxidize of hydrogen on palladium or platinum catalysts devolve with the oxygen chemisorption on catalyst and then with the reaction of the hydrogen from gas stage. The order of the reaction is one for the hydrogen and zero for the oxygen. The paper describes a study about the platinum and palladium catalyst and the mechanism of the reaction between hydrogen isotopes and oxygen using catalysts. (authors)
