N-dodecane partial oxidative reforming in gliding arc discharge plasma and kinetic model

A gliding arc discharge (GAD) plasma reactor was developed for partial oxidative reforming (POR) H2 produc-tion. Air was used as carrier gas and oxidant. The effects of the molar ratio of oxygen to carbon(O/C), input power and residence time on POR reaction were investigated. Under O/C ratio 0.75, input power 35 W and residence time 35 s, the energy yield of H2 was 68.7 L/kWh and the main products were H2 and CO. The GAD plasma was diagnosed with OES. A zero-dimensional(0-D) reaction kinetic model of was established. The simulation results were consistent with the experimental ones. The mechanism of C12H26 conversion, the gen-eration and consumption of products were discussed in detail. The experiment results were in good agreement with the simulated ones. The primary path of n-dodecane conversion was the direct cracking reaction and H2 mainly derived from the recombination reaction between H atom and CH4, C3H6 and C2H6.
