Abstract
Methane reforming to hydrogen production is considered as a top priority for future sustainable energy. Over conventional catalytic reforming, atmospheric pressure non-thermal plasma reforming possesses advantages of feeding flexibility, sulfur tolerance, durability, and fast response. The main drawback of plasma reforming is high energy cost, which results from its monotonic dependence on specific energy input (SEI). To lower the energy cost and increase syngas concentration, an innovative spark-shade plasma reactor was designed, which features extremely enlarged reaction zone arising from rotating spark channels, relative to the narrow channel of conventional spark plasma. In this presentation, methane reforming with added O2 in the spark- shade plasma reactor and the effects of the key parameters were reported. The kinetics of dry reforming of methane in a spark-discharge plasma was studied.
Plasma technologies have been extensively employed on synthesis of TiO2 photocatalysts due to their fast and facile synthesis processes with abundant availability of Ti precursors and oxidants. Photocatalytic TiO2 films by atmospheric pressure plasma chemical vapor deposition (CVD) were reviewed. In our pioneering work, one-step, fast and facile synthesis of full crystalline TiO2 photocatalysts was achieved by gliding arc plasma.
