氢化钚与CO反应体系的耦合效应

摘要

氢化钚与CO反应体系有七个独立组分、四种元素和三个独立反应方程式，分别计算了CO(g)、CO2(g)和H2(g)在同时反应和单独反应中的平衡组成。计算表明：同时反应有耦合作用，低温有利于CO(g)的转化和Pu2O3(s)的生成。与单独反应相比，体系中有较多的Pu2O3(s)生成，其平衡组成也有较大差异。计算结果对钚的表面防腐有一定的参考价值。%There are seven independent component with 4 chemical elements, therefore, the plutonium hydride-CO system involves of 3 independent reactions. The balance masses of CO(g), CO2(g) and H2(g) in simultaneous reaction and single reaction are calculated, respectively. The results show: comparing with that in single reaction, existence of coupling effect and balance masses is very different, more Pu2O3(g) is produced and low temperature is in favor of the transformation of CO(g) and the production of Pu2O3(g). The calculated results are useful to the anti-surface corrosion of plutonium.
