The synthesis of many important chemical products (such as acetic acid, oxalic acid, dimethylformamide, phosgene, etc.) requires high purity CO gas. At the same time, CO gas resources are very rich, but it is often combined with CH4, CO2, N2, H2. It coexists with water vapor and other gases, so it needs to be separated and purified before it can be used.
As a toxic and harmful gas, CO can poison the multidirectional catalysts in the synthesis industry and cause harm to people’s health and life. Therefore, it must be separated, purified, recycled and reused.
