Comparison Studies of Criado and Coats-Redfern Methods for Co-Gasification of Rubber Seed Shell with High Density Polyethylene Mixtures

Abstract

In this present study, the gasification kinetics of rubber seed shell, high density polyethylene, and their mixtures (20/80 and 40/60 weight ratio of HDPE/RSS) are investigated using a non-isothermal thermogravimetric analysis (TGA) system at heating rate of 10 K/min in the temperature range of 323-1173 K. The argon gas is supplied at a flowrate of 100 ml/min and the steam is generated from superheater at 383 K. The steam is injected at flowrate of 300 μL/hour into the TGA system. The Criado and Coats-Redfern methods are used to investigate the reliability of the determined value of the activation energy, EA from the experimental data of TGA. The interaction of solid-phase components based on the mentioned experimental conditions is also studied.
