在近似工业合成氨的实际条件下,研究了我国研制的A系工业催化剂表面上的本征动力学。在用简单的方程的修正表达式对实验数据作电算处理之后,证明了A系催化剂表面的氨合成动力学用方程来描述是基本适用的、有效的。经过电子计算机的优化计算,认为动力学参数a值取0.5较好。所求得的表观活化能与许多学者的研究结果相近。因此,本报告为A系催化剂的工程应用计算,推荐了一个适用的动力学模型以及相应的动力学参数。 通过动力学数据的比较,证实了A110催化剂比A106及国外同类型产品催化剂具有更高的催化活性及较低的活性温区。
Under the actual conditions of industrial ammonia synthesis, the intrinsic kinetics on the surface of A-series industrial catalysts developed in China was studied. After calculating the experimental data by a simple equation of the modified expression, it is proved that the ammonia synthesis kinetics on the surface of catalyst A is basically applicable and effective. After the optimization of computer calculations, that the dynamic parameter a value of 0.5 is better. The calculated apparent activation energy is similar to that of many scholars. Therefore, this report is an engineering calculation of catalyst A, and a suitable kinetic model and corresponding kinetic parameters are recommended. The comparison of kinetic data shows that A110 catalyst has higher catalytic activity and lower active temperature zone than A106 and similar foreign products.
