| Name | adsorbent for desulfurization (Ⅲ) |
| Synonyms | adsorbent for desulfurization(Ⅳ) adsorbent for desulfurization (Ⅱ) adsorbent for desulfurization (Ⅲ) adsorbent for desulfurization (Ⅰ) |
| use | is mainly used for fine desulfurization of various industrial raw gas such as semi-water gas, natural gas, shift gas, lime kiln gas, etc., and can also be used for desulfurization of flue gas such as power plants. The modified activated carbon not only has adsorption performance, but also absorption performance. Therefore, it can be used alone or in series with zinc oxide desulfurizer to achieve the purpose of fine desulfurization. Taiyuan Xinhua Activated Carbon Factory, Beijing Beijiao Activated Carbon Factory, etc. remove H2S produced in the production process of natural gas, refinery gas, coking, benzene production, coal to gas, pesticides, man-made fibers, etc. It is also used to remove mercaptan, carbon, oxygen and sulfur and desulfurization of flue gas from power plants. |
