Co-Mo-K催化剂上COS、HCN转化率的热力学分析

Thermodynamics of COS and HCN equilibrium conversion on Co-Mo-K catalyst

利用热力学基础数据和相关软件对Co-Mo-K催化剂上COS、HCN加氢和水解反应进行了热力学计算。在热力学上,COS、HCN加氢和水解反应在耐硫变换条件下均为自发过程。计算结果表明在Co-Mo-K耐硫变换条件下COS、HCN主要发生的是水解反应,该结果与工业经验数据基本一致,可以作为工业实际借鉴。

The thermodynamics equilibrium conversion of COS and HCN on Co-Mo-K catalyst were calculated according to some thermodynamic data and related software. The hydrogenation and hydrolysis of COS, HCN can occur spontaneously under the conditions of sulfur tolerant shift reaction because of the low negative value of AG thermodynamicaUy. The calculation reveal that COS, HCN hydrolyzing is the main reaction under the conditions of sulfur tolerant shift reaction in accord with empirical data of industrial.
