Present study deals with the simulation of the Fenton’s process for the removal of phenol using ASPEN-Plus. The effect of phenol concentration, catalyst loading, mole ratio of H2O2 to iron ion, and temperature on the phenol degradation rate has been studied using the developed process flow diagram. The result shows higher flow rate of hydrogen peroxide (4.2 kmol/h) favours phenol degradation (98%) since the hydroxyl radical availability rises. Increase in catalyst loading (186 g) and rise in mole ratio of hydrogen peroxide to iron ion (~1) improves the removal of phenol (~97%) from wastewater since the hydroxyl radical formation improves and thus affect the mechanism and chemical kinetics of Fenton reaction. Increase in temperature improves the degradation, however high temperature above optimum condition (32.5C) does not favour the degradation of phenol.

ASPEN-Plus对芬顿法降解苯酚的模拟研究

目前的研究涉及模拟 Fenton 使用 ASPEN-Plus 去除苯酚的过程。使用开发的工艺流程图研究了苯酚浓度、催化剂负载、H2O2 与铁离子的摩尔比和温度对苯酚降解速率的影响。结果表明，过氧化氢的更高流速（4.2 kmol/h）有利于苯酚降解（98%），因为羟基自由基的可用性增加。增加催化剂负载量 (186 g) 和提高过氧化氢与铁离子的摩尔比 (~1) 提高了从废水中去除苯酚 (~97%) 的能力，因为羟基自由基的形成得到改善，从而影响反应机理和化学动力学芬顿反应。温度升高会改善降解，但是高于最佳条件的高温 (32.
