Abstract:
In recent years, the plasma hydrogen-generation technology has attracted wide attention due to its advantages of rapid start-up and shutdown, and of possessing various types of fuel to be processed, etc. Rotating gliding arc (RGA) plasma is a kind of non-thermal equilibrium plasma, which has the characteristics of both hot plasma and cold plasma. And it is a research hot spot in the field of hydrogen-generation from fuel reforming. In this paper, the principle and performance evaluation index of hydrogen-generation by RGA plasma are briefly introduced. And the research progress of the conversion rate of reactants, hydrogen selectivity and energy efficiency of hydrogen-generation from ethanol, methanol and methane by RGA plasma in recent five years are summarized, analyzed, and prospected. Based on the current research status, some suggestions are put forward for the optimization of energy efficiency and hydrogen selectivity. It is believed that a lot of research work still remains to be completed in optimizing the power supply design, improving the impedance matching between the RGA plasma reactor and the power supply, and analyzing the mechanism of hydrogen production by RGA plasma. Research shows that the RGA plasma coupled catalytic bed reactor can improve the reactant conversion and hydrogen selectivity, which is an important research direction to promote the development of plasma hydrogen technology.
