The contribution of oxidation removers to humans and the Environment
Carbon monoxide (CO) is a dangerous and toxic air pollutant that seriously affects humans, plants, animals and the environment. It is mainly found in industrial smoke, automobile exhaust, severe traffic congestion, homes that burn wood indoors, and natural sources such as forest fires. In order to control it,
CO oxidation is mainly carried out by catalytic converter, which is a feasible technology for CO removal. There are many kinds of catalysts used in catalytic converters, such as precious metals, base metals, perovskites, spinel, carbon monoxide catalysts, etc., among which carbon monoxide catalysts have good thermal activity, selectivity and availability for low temperature oxidation of CO. A hopcalite catalyst was prepared by different methods. The activity of Hopcalite catalyst was influenced by oscillating temperature and pH (8-11.5). Carbon monoxide catalyst The reaction process of catalyst in CO catalytic oxidation and the key factors affecting its activity: suitable accelerator, carrier, pretreatment and advanced preparation method. At a low temperature of 50 ~ 125℃, the CO conversion rate is significantly higher than 100% when additional O2 is added to the feedstock gas. In fact, carbon monoxide catalysts are considered to be readily available and highly active catalysts that can achieve complete oxidation of CO at low temperatures (25 ° C) at low cost. The activity and stability of carbon monoxide catalyst in CO oxidation were improved by adding accelerators, carriers, pretreatment and advanced preparation methods. In addition, deactivation usually occurs through the sintering and scaling of carbon monoxide catalysts during the CO oxidation process.
