Plasma catalytic bamboo shavings to produce high-quality syngas: Mechanism for Yield Optimization and Electrochemical Performance Enhancement

By adjusting different plasma atmospheres (especially oxygen concentration), it was found that oxygen plasma could significantly enhance the gasification efficiency: when the oxygen concentration was 8%, the yield of high-quality syngas reached a peak of 162.1 mL, and the calorific value of the syngas significantly increased, reaching 13.26 MJ/m3.

Plasma not only accelerates the decomposition of biomass macromolecules through high-energy electron collisions and active oxygen species, promoting the release of volatile matter and the generation of small molecule gases, but also achieves efficient gasification at a lower temperature. At the same time, the microstructure of the solid product, bamboo charcoal, was also optimized. Oxygen plasma treatment effectively promoted pore development and introduced oxygen-containing functional groups.
