Research on catalytic removal technology of carbon monoxide from industrial waste gas

Industrial waste gas is a harmful gas produced in the production process of factories, in which carbon monoxide (CO) is a common toxic component. Carbon monoxide is colorless and odorless, and when inhaled, it can make people feel dizzy, nauseous, and even fatal in severe cases. In addition, it pollutes the air, exacerbates smog and global warming. Therefore, how to efficiently remove carbon monoxide in industrial waste gas has become an important topic in the field of environmental protection.
Currently, the most effective removal method is to use a catalyst to convert carbon monoxide into non-toxic carbon dioxide (CO₂). The key to this technology is the catalyst, which speeds up the chemical reaction, allowing carbon monoxide to quickly turn into carbon dioxide at lower temperatures. There are two commonly used catalysts: one is a precious metal catalyst, such as platinum, palladium, the effect is very good but expensive; The other is transition metal oxide catalysts, such as oxides of copper, manganese, and cobalt, which are less costly but less effective.
In order to improve the performance of catalysts, scientists have done a lot of research:
Increased activity: By changing the structure of the catalyst, such as making it into nanoparticles or adding other elements, it is easier to "catch" the carbon monoxide and convert it.
Reduce the reaction temperature: the catalyst can work efficiently at room temperature or low temperature, saving energy.
Enhance anti-interference ability: industrial waste gas often contains impurities such as sulfur and water vapor, which is easy to make the catalyst "toxic" failure. Scientists make the catalyst more durable by improving its surface or adding protective materials.
Extend service life: study how to "revive" deactivated catalysts, reduce the frequency of replacement, and reduce costs.
In the future, with the advancement of technology, this technology will play a greater role in industrial waste gas treatment, helping us to protect the environment and achieve green production.
