Abstract

In this research, thermal decomposition characteristics of cellulose with electron injected air were investigated in a laboratory scale reactor based on the principle of the groundbreaking organic substance reduction device ERCM (Earth-Resource-CeramicMachine), which was developed by a Japanese venture company. A 12 V voltage electron generator as the key part, was adopted to inject electrons into the air for accelerating the thermal decomposition of carbonaceous materials during the ERCM process. A modified fixed bed reactor was adopted to investigate the effects of different parameters including the on/off of electron injection into the air and the thermal decomposition temperatures (350-500O C) on the decomposition degree (volume reduction rate) and the syngas generation of pure cellulose. It was found that the thermal decomposition reaction was more accelerated with the electron-ON case than that with the electron-OFF case. In addition, it was shown that the volume reduction rate of cellulose in the electron-ON case was higher by 4.4% to 18.3% than that in the electron-OFF case. These results suggest that electron injected air may accelerate the thermal decomposition of solid wastes.
