| Use | carbon monoxide is the main component of synthesis gas and all kinds of gas, is an important raw material of organic chemical industry, it is the basis of C1 chemistry, from which a series of products can be made, such as methanol, acetic acid, phosgene, etc., which are used as reducing agents in the gold industry. At present, the industrialized C1 Chemical production technology mainly includes:(1) acetic acid synthesis. (2) synthesis of acetic anhydride. (3) synthesis of oxalic acid. (4) Fischer-Tropsch synthesis. (5) The mobier method. used in the preparation of Sodium Formate, as reducing agent in the metallurgical industry used as reducing agent in the metallurgical industry |
| production method | carbon monoxide is produced in many industrial processes, such as ammonia synthesis feed gas, tail gas of yellow phosphorus production and blast furnace gas and converter gas in iron and steel industry. From the carbon monoxide resources, a large number of steel gas. In the case where the purity of carbon monoxide is required to be high and the amount required is not particularly large, a carbon monoxide production plant is often established, or a by-produced gas with a lower treatment cost is utilized. There are several common methods. 1. Coke oxygen method 2. Carbon dioxide and charcoal reduction method carbon dioxide is introduced into the charcoal layer of the electric furnace to be reduced to carbon monoxide 3. Synthetic ammonia copper washing regeneration gas method. |
