Volatile organic compounds (VOCs) decomposition by non-thermal plasma (NTP) has been receiving increasing attention from the scientific communities due to its advantages of easy operation, high efficiency, energy saving, and non-secondary pollution. But most of the researches are doing experiments and existing experiment methods cannot observe the micro physical and chemical processes. In order to make up for the deficiency of the experiment, herein, a numerical method was developed to analyze the decomposition behavior of HCN, C₃H₃N, C₃H₈, C₃H₆, CO, and NO in the VOCs treatment by NTP. Results indicated that increasing electron density or energy was beneficial to VOCs decomposition, but when the electron density and energy was too high, the promotion would be weakened. The influences of initial concentration of O₂ and H₂O on different VOCs decomposition were totally different. The increase of initial concentration of oxygen was beneficial to the decomposition of HCN, C₃H₈, CO, and NO, but the high concentration of oxygen could promote to generate C₃H₆ at the initial reaction stage. The decomposition of HCN and C₃H₃N are not restricted by dry or wet conditions, but the increase of the concentration of water vapor is advantageous to the decomposition of C₃H₈, CO, and NO.
