The chemical reactions that induce the decomposition offormaldehyde have been investigated using the Monte-Carlo simulationmethod. The simulation results, of plasma chemical reaction kineticsin pulsed discharge, showed that the pulse width of applied voltageshould be in the range of 100-500 ns to maintain a higher density ofradicals. The higher electron density was due to a higher radicaldensity. Furthermore, increasing the content of oxygen and H_2O ingas would obtain a higher radical density.
