| 摘 要： | 在催化剂的作用下,CO分子间存在氧同位素和碳同位素重排达到热力学平衡的现象。通过分析12C18O和13C16O反应生成12C16O和13C18O的同位素形态,从而得到合适的反应条件。在实验中,研究了反应温度、反应压力以及空速等因素对12C18O转化率的影响。结果表明,在260Torr,400℃,空速为0.5mL/(g·min)条件下,12C18O的转化率可以达到80%。

| Abstract: | 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）. |
