How to remove carbon monoxide from compressed gas?

Carbon monoxide (CO) is a colorless, odorless gas, but it is an extremely dangerous substance. In compressed gases, carbon monoxide can cause serious hazards, including poisoning, explosion, and component aging. However, since carbon monoxide is difficult to adsorb, special methods are required for purification. The most common method is to use a highly active catalyst, which can remove carbon monoxide at room temperature.

When oxygen is present in the compressed gas, a catalyst can be used for catalytic conversion. This method uses a catalyst to cause carbon monoxide to react with oxygen to produce carbon dioxide (CO2). Catalysts are usually made of copper and manganese metal oxides, which are highly active and can accelerate the reaction rate. The specific steps of catalytic conversion are to pass the compressed gas through the catalyst layer, and the active sites on the catalyst convert carbon monoxide and oxygen into carbon dioxide. This method effectively removes carbon monoxide, making compressed gas safer.

When there is no oxygen in the compressed gas, new oxygen-free materials can be used to convert carbon monoxide into carbon dioxide. This method takes advantage of the chemistry of special materials that convert carbon monoxide into carbon dioxide in an oxygen-free environment. This material has good adsorption properties and reactivity. By passing the compressed gas through this material layer, the carbon monoxide will be directly oxidized into carbon dioxide by the active material. The material can be regenerated after consumption, allowing it to be reused. This method can also effectively remove carbon monoxide in an oxygen-free environment.

When dealing with carbon monoxide, there are specific conditions to choose from. First, you need to consider whether the gas contains oxygen. If there is oxygen, you can choose a catalyst for catalytic conversion. If there is no oxygen, you can choose oxygen-free new materials for conversion. In addition, factors such as the nature, temperature, and pressure of the compressed gas being processed also need to be considered to select the appropriate catalyst or material. In addition, attention needs to be paid to the stability and lifespan of the catalyst or material to ensure efficient purification over a long period of time.
