Application Case | ATP2400: Unveiling the Gasification Mechanism of PTFE in Thermal Plasma

2026-01-07

In recent years, with the growing volume of fluoropolymer waste, the environmentally sound treatment of highly chemically stable materials like polytetrafluoroethylene (PTFE) has become a pressing concern. Finding ways to efficiently process PTFE while avoiding the generation of toxic fluorides is a significant challenge in environmental technology.

01 Research Context: PTFE Disposal and the Plasma Challenge

PTFE's inherent chemical stability makes it resistant to decomposition by conventional methods. Thermal plasma technology offers ultra-high temperatures and highly reactive species for this purpose, but directly observing its reaction processes is difficult. Precisely measuring the temperature and composition within the plasma reaction zone is a prerequisite for optimizing the process and validating computational models.

02 Key Technology: The Role of OES in Plasma Diagnostics

Optical Emission Spectroscopy (OES) is a non-invasive diagnostic technique. By analyzing the characteristic spectra emitted by excited substances, it can determine plasma temperature, composition, and the concentration of reactive species.

A recent study published in Nature Communications systematically revealed the degradation mechanism of PTFE during thermal plasma gasification by combining multi-scale simulation with experimental validation. The research not only theoretically proposed two degradation pathways for PTFE under oxygen and steam atmospheres but also experimentally achieved a high gaseous fluorine recovery rate of 80.12%, offering a new approach for efficient PTFE resource recovery. In this cutting-edge research, OES technology played an indispensable role.

ATP2400 spectrometer was used to collect emission spectra from the plasma jet. By comparing experimental spectra with standard spectral libraries, researchers accurately determined the core plasma temperature (4500K–4750K) at different power levels, providing critical input parameters for subsequent reaction simulations.

03 ATP2400: A Spectral Solution for Demanding Environments

ATP2400 offers high resolution, high sensitivity, and strong anti-interference capability. It is suitable for high-temperature, high-radiation plasma environments, enabling the stable acquisition of reliable spectral data to support end-to-end research from experimentation to simulation.

04 Broad Applications of OES Technology

OES technology is not only vital for advanced research but also plays a key role across multiple industrial sectors:

Semiconductor Manufacturing: Monitoring plasma processes (etching, deposition).
Energy & Combustion: Monitoring combustion temperature and pollutants.
Material Processing: Diagnostics for processes like laser welding and arc additive manufacturing.
Environmental Monitoring: Online analysis of industrial exhaust gas components.
