Sliding arc discharge plasma is a normal temperature and pressure non-equilibrium plasmas , it is both thermal plasma and plasma characteristics, high energy conversion efficiency , and the equipment is simple, easy to operate, therefore , gliding arc discharge plasma body as a new hydrogen technology , has a good application prospect. In this paper, gliding arc discharge plasma , respectively, ammonia and methane gas as a raw material , to carry out a gliding arc discharge plasma fuel reformer hydrogen experimental research focus of the study of the discharge voltage , intake air flow and other parameters of the reaction ratio of raw materials effects , while the blade gliding arc discharge plasma generation method has been improved, designed a rotating gliding arc discharge plasma generating device , and use it for the experimental study of methane reforming . The results show that gliding arc discharge plasma technology can be the case in the absence of a catalyst , to achieve ammonia decomposition of hydrogen under normal temperature and pressure . The rise of discharge voltage can be increased ammonia conversion rates while reducing hydrogen consumption ; intake air flow rate will decrease the ammonia conversion rate , but the consumption of hydrogen is relatively complex, hydrogen consumption will be then reduce elevated ; nitrogen ammonia decomposition rate of added help to improve . Rotary gliding arc discharge plasma in a nitrogen atmosphere, the decomposition of methane , the main product of the decomposition products include solid carbon and gaseous products hydrogen, ethylene , and acetylene . Discharge voltage and the increase of the nitrogen concentration can increase the methane conversion rate, the intake air flow rate will reduce the rise of the reaction gases in the plasma region the residence time of the plasma while reducing the energy density within the region , thereby reducing the methane conversion rate . Rotating gliding arc discharge plasma hydrogen methane partial oxidation reforming process, the discharge voltage is a very important parameter , the discharge voltage is higher, the more favorable the reaction ; intake air flow rate is increased, the hydrogen consumption will be reduced after l ; reactor cover change on methane reforming reaction can also have some effect ; excess air ratio increases , the hydrogen selectivity first increased and then decreased, experimental results show that a slight excess of air will help hydrogen selective increased.
