Abstract:

In the 21st century, as China continues to witness a proliferation of chemical production facilities, the generation of oxygen-containing organic gases in various chemical processes has emerged as a critical concern. The safe disposal of these gases through deoxidation has become a pivotal challenge. However, the development of deoxidation technology faces numerous challenges, primarily due to the variability of conditions, intricate compositions, and substantial variations in deoxidation depth. This paper summarizes the application and recent research progress of chemical deoxidation technology of O₂-containing organic gases in chemical processes. The applicability and technical competitiveness for various technologies are analyzed based on the deoxidation requirements in different situations. In view of the high oxygen content, large flux and continuous O₂-containing gas deoxidation formed in chemical production process, it is pointed out that catalytic deoxidation exhibits distinct advantages of short process, strong operability and excellent deoxidation performance, which is more competitive in the current practical industrial application. Concurrently, it is imperative to focus on achieving deep deoxidation, addressing high-O₂-content gases, as well as implementing mild deoxidation techniques.

Key words: O₂-containing gases from chemical plant, deoxidation via chemical methods, industrial application
