Carbon monoxide is the main component of synthesis gas and various types of coal gas. It is an important raw material of organic chemical industry and the basis of C1 chemistry. It can produce a series of products, such as methanol, acetic acid, phosgene, etc., and is used in the chemical industry of metallurgy. as a reducing agent. The currently industrialized C1 chemical production technologies mainly include: (1) Synthesis of acetic acid. (2) Synthesis of acetic anhydride. (3) Synthesis of oxalic acid. (4) Fischer-Tropsch synthesis. (5) MOBILE ACT.
