Study of Manganese-Base Catalysts for Catalytic Wet Air Oxidation of Phenol

Abstract

苯酚为常见水污染物之一,对其进行处理具有深远意义。目前,去除水中苯酚的有效方法之一为催化湿式氧化法(CWAO)。先前众多研究均表明MnCeOx催化剂是一种高效催化湿式氧化苯酚用的催化剂。然而,对其稳定性却并未作出深入研究。因此,本论文基于MnCeOx催化剂为研究基础,通过改良催化剂制备方法以及调控合适的Mn/Ce比,制备出相对高效稳定的MnCeOx催化剂,并初步探究其高效稳定的作用机制。此外,为进一步降低成本,本论文拟用优化后的新型方法即氧化还原-水热法制备单一过渡金属氧化物MnOx催化剂,使其即使不含Ce下也可实现高效稳定的处理苯酚。本论文以自配苯酚溶液为模拟废水,利用TOC、HPLC及AA...Phenol is one of the common water contaminants, decomposed it into harmfulness CO2 or at least less harmful compounds has profound significance. At present, catalytic wet air oxidation (CWAO) is an effective method to degrade phenol in water. Many previous studies have shown that MnCeOx catalysts demonstrating remarkable activity for the degradation of phenol. However, the stability of MnCeOx cata...学位:工学硕士院系专业:化学化工学院_化学工程学号:2062014115139
