How does the carbon monoxide catalyst work in the PPU air separation system? What is its application principle?

PPU air separation system refers to the application of air separation prepurifier in air separation equipment. It is mainly used to remove impurities and harmful substances in the air. It uses physical or chemical methods to adsorb or react impurities such as moisture and nitrogen oxides in the air, thereby achieving the purpose of purifying the air. In the air separation process, carbon monoxide (CO) is a common by-product, and its production is mainly caused by the combustion of carbonaceous fuels and some chemical reactions.
Carbon monoxide is a colorless, odorless gas that looks "harmless to humans and animals", but it is seriously harmful to humans and the environment. It can bind to hemoglobin in human blood, reduce the blood's oxygen-carrying capacity, cause hypoxia in the human body, and cause symptoms such as headaches, dizziness, and even coma, which can be life-threatening in severe cases.
Carbon monoxide removal catalysts can effectively degrade carbon monoxide in air separation systems, thereby reducing its threat to human health and the environment. Its core function is to accelerate the chemical reaction of carbon monoxide and oxygen to convert it into carbon dioxide.
There are many special active sites on the surface of carbon monoxide removal catalysts, which can adsorb carbon monoxide molecules and oxygen molecules. This process is to reduce the activation energy of the reaction through the principle of catalytic oxidation, so that the reaction that originally requires higher energy to occur can proceed smoothly under relatively mild conditions.

Carbon monoxide removers play an important role in environmental protection. With the continuous development of science and technology, I believe that it will make greater contributions to mankind in the future.
