What are the success stories of carbon monoxide catalysts in practical applications?

 Carbon monoxide catalyst in automobile exhaust gas purification, industrial waste gas treatment and indoor air purification have a great contribution.
In the exhaust gas treatment system of modern automobile, the three-way catalytic converter is a typical successful application case. It contains carbon monoxide catalysts (mainly precious metal catalysts such as platinum, palladium, rhodium, etc.), which are capable of simultaneously treating carbon monoxide, hydrocarbons, and nitrogen oxides.
When the exhaust gas from the automobile engine passes through the three-way catalytic converter, at the right temperature (usually about 200-400 ° C to work efficiently), the carbon monoxide catalyst promotes the reaction of carbon monoxide with the oxygen in the exhaust gas to oxidize carbon monoxide to carbon dioxide. For example, in some countries and regions with strict requirements for vehicle exhaust emission standards, such as the European Union and California, automobile manufacturers continue to optimize the performance of carbon monoxide catalysts in three-way catalytic converters to meet increasingly stringent emission standards. The application of this technology makes the emission of harmful gases such as carbon monoxide in automobile exhaust effectively controlled, thus improving air quality and reducing the harm to human health.
In the iron and steel industry, blast furnace gas containing carbon monoxide is produced in the process of blast furnace ironmaking. Previously, most of the carbon monoxide in these blast furnace gas was directly burned and discharged, which not only wasted resources, but also caused pollution to the environment. It is now possible to convert carbon monoxide from blast furnace gas by using a carbon monoxide catalyst.
For example, some steel companies have adopted a carbon monoxide conversion process based on copper-zinc oxide catalysts. In this process, carbon monoxide reacts with water vapor in the presence of a catalyst to produce carbon dioxide and hydrogen. The hydrogen generated can be used as clean energy for other production processes in the steel plant, such as cold rolling, pickling, etc., or for power generation. At the same time, the direct emission of carbon monoxide is reduced, and the pollution to the environment is reduced. This application case not only realizes the effective use of resources, but also conforms to the concept of green development.
In some closed or semi-closed Spaces such as underground parking lots and mines, the accumulation of carbon monoxide may cause harm to the human body. Carbon monoxide catalysts are used in air purification equipment to effectively remove carbon monoxide from the air.
For example, in some large underground car parks, ventilation systems containing carbon monoxide catalysts have been installed. When the concentration of carbon monoxide in the parking lot rises, the carbon monoxide catalyst in the ventilation system (such as the catalyst with manganese dioxide as the main component) oxidizes the carbon monoxide into carbon dioxide, and then exhausts the purified air through the ventilation equipment. This can keep the air quality in the parking lot good and provide protection for people's health. In the mine, carbon monoxide is a common harmful gas, the use of carbon monoxide catalyst air purification equipment can effectively protect the safety of miners.
