本文作者已经实验考察了甲醇在负载银和电解银催化剂上的氧化过程。观测到该反应系统在某些特定条件下会发生催化剂表面的温度振荡和反应产物的浓度振荡,确定了“稳定—振荡—稳定”区域,并初步探讨了产生化学振荡现象的物理化学机理。本文试图对这种催化反应过程中的振荡行为进行数学模拟。
The authors have experimentally investigated the oxidation of methanol over supported silver and silver electrolysis catalysts. It was observed that the temperature of the catalyst surface and the concentration of the reaction product oscillate under certain conditions and the “stable-oscillatory-stable” region was determined. The physico-chemical mechanism of the chemical oscillation . This article attempts to simulate the oscillatory behavior during this catalytic reaction.
