Uses
Carbon monoxide is the main component of syngas and various types of coal gas, an important raw material for organic chemicals, and the basis of C1 chemistry, which can be used to manufacture a series of products, such as methanol, acetic acid, phosgene, etc., and is used as a reducing agent in the metalworking industry. At present, the industrialized C1 chemical production technology mainly includes: (1) acetic acid synthesis. (2) Acetic anhydride synthesis. (3) Oxalic acid synthesis. (4) Fischer-Tropsch synthesis. (5) Mobile method. |

Production method
Carbon monoxide is produced in many industrial processes, such as ammonia feedstock, yellow phosphorus production exhaust, and blast furnace and converter gases in the steel industry. In terms of carbon monoxide resources, the amount of gas in steel mills is huge. In cases where the purity requirements for carbon monoxide are high and the demand is not particularly large, carbon monoxide production equipment is often established, or by-product gas with lower treatment costs is used. The commonly used methods are as follows. 1. Coke oxygen method 2. Carbon dioxide and charcoal reduction method The carbon dioxide charcoal layer that passes through the electric furnace is reduced to carbon monoxide 3. Synthetic ammonia copper washing and regeneration gas method. |
