By DBD plasma technique,the liquefaction mechanism of solid burnable including coal and biomass was studied in the paper to explore a new way to utilize energy.According to collision theory and Boltzmann equation,the rate coefficients of dissociation reaction causing by collision of high energy electrons were simulated numerically.Comparing computed results with experimental curves,the model was verified correctly and reliably.At certain electrons temperature,the state of generous particles and the progress of the reaction can be predicted by contrast with the rate coefficients of different dissociation reaction.It would pave ways for analyzing the liquefaction reaction of solid burnable,controlling the process of reaction and forecasting the composition of liquefied products under DBD plasma.
