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) H 2 production. 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 H 2 was 68.7 L/kWh and the main products were H 2 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 C 12 H 26 conversion, the generation 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 H 2 mainly derived from the recombination reaction between H atom and CH 4 , C 3 H 6 and C 2 H 6. [Display omitted] • A GAD reactor was used for POR of n -dodecane for hydrogen production. • A 0-D kinetic model was developed to explore the mechanism. • The results of OES were used to analyze the generation and consumption of substances. • The direct cracking reaction contributes the most to the n -dodecane conversion.
