Abstract:Tetrafluoromethane (CF4) is one of the typical non-carbon dioxide gases with super stronggreenhouse effects, legally regulated by Kyoto Protocol. CF4 emissions continue to increase with thecontinuous expansion of industrial activities such as aluminum electrolysis and semiconductor, resultingin the aggravation of global climate change and deterioration of environment on which human survivaldepends, as well as the hindering of the sustainable development of related industries. Intensifying thecontrol of non-carbon dioxide greenhouse gases such as CF4 is an important part of China's " carbonpeaking and carbon neutrality goals" strategic objectives with the implementation of the action plan.Firstly, the sources of CF4 are analyzed systematically, and the main industry sources, emission char⁃acteristics and generation mechanism of CF4 are expounded in this paper. Then, the limitation of sourceemission reduction of CF4 and the inevitable trend of pipe-end treatment are emphatically analyzed aftersummarizing the status of source emission reduction measures of CF4. As for the end treatment of CF4,seven pipe-end treatment technologies, including deep-cooling separation, adsorption, membrane sep⁃aration, thermal combustion, thermal catalytic decomposition, plasma high-energy decomposition andelectrocatalytic decomposition, are summarized from the perspective of physical and chemical treatment.Meanwhile, the basic principles, application cases and development status of relevant methods are de⁃scribed. Some parameters such as temperature, decomposition product, energy consumption, as well asthe advantages and disadvantages of each technology are compared and analyzed. In the final, thefuture challenges of CF4 pipe-end treatment technology are predicted and evaluated based on the indus⁃try requirements and application scenarios. Close-
