Biomass Char Gasification with Carbon Dioxide As An Alternative Energy

Abstract

Currently, the main energy source are fossil based fuel. Utilisation of conventional fossil fuel is contributing to greenhouse gas emissions which causes climate change. Attention to renewable energy sources has increased nowadays to reduce the high dependence on fossil fuel which is considered not renewable. Biomass seems to be a promising and environmental friendly feedstock that can be converted into useful products (biochar, bio-oil and syngas). One of the method to convert biochar to syngas is through the gasification technology. When biochar is reacted with gasifying agent like CO2 and H2O at high temperatures, syngas which is rich in hydrogen can be produced. The main objectives of this work are to study the gasification behaviour of pineapple peels in Thermogravimetric Analyzer (TGA) using CO2 as its gasifying agent. The effect of temperature towards char reactivity and carbon conversion were determined. In conclusion, this study provides information on utilisation of biomass waste as an energy source through gasification technology.
