Abstract: Hydrogen-rich syngas produced from ethanol/water mixtures by pulsed electrodeless discharge is studied in this work. A plate-pinhole-plate device is used to achieve electrodeless discharge that positive and negative discharge can simultaneously generate in both sides of the pinhole. The study find that the gas production efficiency is higher when both sides are spark discharge. Among the produced gas, H2, CO are the main components, which account for about 99%. Meanwhile, in order to acquire hydrogen-rich syngas with high yield, both high peak voltage and appropriate electrode distance are important. The reaction process is also researched by the spectral diagnosis. The results show that the generation of ·H is the key for syngas production by pulsed electrodeless discharge that ·H is not only the important substance for hydrogen production, but also affects the generation of ·CH and ·C2 thereby determining the CO production.
