摘要

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。

Abstract

Under the conditions similar to industrial ammonia synthesis

the intrinsic kinetics of Series "A" Catalysts (A110

A106) made in China for ammonia synthesis has been investigated. After the experiment data have been correlated by corrective expression of simple Temkin-Pyzhev equation

it is found that this equation is also valid for intrinsic kinetics of Series "A" Catalysts in ammonia synthesis. With the aid of computation of optimum program

we find that it is most desirable to take the value of 0.5 for a in Temkin-Pyzhev equation. The apparent energy of activation has been found to be between 40

000-45

000 kcal/kg-mol. This agrees to the results found by the previous workers. A suitable kinetics equation and kinetics parameters for application to engineering are suggested. By comparative study of kinetic data

the author have verified that the performance of catalyst A110 is better than A106 and those foreign-made commercial catalysts of same type

especially in the lower temperature range.
