Abstract

Decomposition characteristics of acetone in an atmospheric DC corona discharge are investigated for the different gas composition of a background gas, nitrogen-oxygen mixture. CO₂, CO, CH₄, HCHO, HCOOH and HCN are products from acetone, and CO₂ is a major and end-product. CO, CH₄, HCHO, HCOOH and HCN are intermediate products, the concentrations of which depend on that of oxygen. Decomposition rate of acetone is not affected by the oxygen concentration very much, but acetone is chiefly inverted to CO₂ via CO at high oxygen concentration (20%) and via CO and CH₄ at low oxygen concentration (0.2%). The percentage of the carbon atoms contained in the gaseous products decreases, when the oxygen concentration increases. NO_x probably takes an important role in the production of CO, CH₄, HCHO, HCOOH and HCN at low oxygen concentration.
