Efficient Conversion of Greenhouse Gas into Value-Added Chemicals with Non-Thermal Nanosecond Pulsed Plasma

Converting greenhouse gas into value-added chemicals and fuels is one of the biggest technical challenges in 21st century¹. Non-thermal plasma (NTP) technology is a promising way to tackle this challenge, owing to its high efficiency in overcoming the thermodynamic limitation of reactions under mild conditions. In this paper, non-thermal plasma driven by nanosecond pulse power source, has been utilized for CH4 dry reforming and CO2 hydrogenation in a dielectric barrier discharge reactor. The effects of electrical parameters (including pulse rising & falling time, pulse repetition frequency, pulse width and applied voltage) and CO2 molar fraction on conversion performance and gas product distribution have been investigated².
