Abstract

This study reports the component of tar produced from oxidative pyrolysis of cellulose and polypropylene with electron-injected air using a laboratory-scale reactor. This experiment was conducted using a cylindrical fixed bed reactor with a fixed bed. The feedstock tested in this study was cellulose and polypropylene. During experiments, the feedstock was heated by an electric heater to 600, or 700 °C with or without electron- injection into the air. Under all experimental conditions, oxidative pyrolysis occurred immediately after the start of the test. The analysis results of absorbed liquid tar samples show significant differences were observed between with or without electron injection. Electron injection gave a clear impact on tar production during the oxidative pyrolysis of cellulose and polypropylene decomposition.
