Abstract

This study reports the component of syngas and tar produced from oxidative pyrolysis of polypropylene with electron-injected air using a laboratory-scale reactor. This experiment was conducted using a cylindrical fixed bed reactor. The feedstock tested in this study was polypropylene. During experiments, the feedstock was heated by an electric heater to 500, 600, and 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 syngas and tar samples show no significant effects of electron injection at 500°C while significant effects were observed at 600°C and 700°C. Electron injection gave a clear impact on syngas and tar production during the oxidative pyrolysis of polypropylene.
