The exhaust gases emitted from coal chemical and petrochemical processes can contain harmful chemicals to the environment. These gases should be eliminated based upon various regulations. As a leader in the innovation catalysts, we have developed a range of catalysts to convert harmful chemicals to non-toxic substances. For instance, the nitric acid production processes generate NO_x contained in the exhaust gas. Our KC-201/202 catalyst is suitable for NO_x removal by converting to N₂ and H₂O. Our catalysts are able to eliminate the following gases:

Carbon monoxide (CO)

Nitrous oxides (NO_x)

Nitrogen oxide (N₂O)

Hydrogen sulfide (H₂S)
