Study on Rate Constant in Hydrogen-Water Isotope Catalytic Exchange Reaction

The kinetic equation in a countercurrent hydrogen-water isotope catalytic exchange reaction was derived.In glass bed packed with 1∶4 Sandwich layers of Pt-PTFE catalyst and stainless steel θ packing,effects of temperature(T)and ratio of gas-liquid(λ)on rate constant k were discussed,and the difference between rate constant k and mass transfer coefficient Kya were compared.The results show that k is increased with T and λ increasing.Kya is more sensitive to T and gas velocity than that of k.
