Experimental Study on the Isotopes Exchange in CO Molecular

It was studied that the rearrangement of oxygen isotopes and carbon isotopes in CO molecular caused by thermodynamic equilibrium in the presence of catalyst. The appropriate reaction conditions was obtained by analyzing the reactants of ¹²C¹⁸O and ¹³C¹⁶O as well as the reaction products ¹²C¹⁶O and ¹³C¹⁸O. The effects of temperature, pressure and space velocity on the conversion of ¹²C¹⁸O were studied in the experiments. It shows that the conversion of ¹²C¹⁸O can reach 80% at the conditions of 260 Torr, 400 ℃ and space velocity of 0.5 mL/（g•min）.
