Kinetic characteristics in pyrolysis of RPF with additives

Abstract

PVC (polyvinyl chloride) was isolated from waste plastic before manufacturing RPF (refuse paper & plastic fuel), and the characteristics of manufactured RPF including properties, calorific value, pyrolysis, chlorine content and kinetics analysis were analyzed. Based on the result of TGA (Thermogravimetric analysis), the kinetics characteristics was analyzed by using Kissinger method and Ozawa method which are the most common methods for obtaining activation energy, and the experimental conditions of TGA were set as follows: in a nitrogen atmosphere, with gas flow rate of 20 mL/min, heating rate of 5-50 °C/min, and maximum temperature of 800 °C. In conclusion, the activation energy showed a tendency to gradually increase by a rise of reaction rate. Although the activation energy with pyrolysis of RPF was irregularly scattered, it was shown that the activation energy was stabilized by co-pyrolysis of RPF and additives (rice bran and sawdust).
