As a renewable source of energy and chemicals, biomass gasification has received unprecedented attention. Partly due to government regulation and partly due to unsolved technological hurdles (e.g., lack of reliable modelling tool for biomass gasification, lack of dominant design, fuel flexibility, efficiency, tar reduction, gas cleaning, scaling up), biomass gasification is still a promising technology after over 30 years' research and development (R&D) and has success only in a few niche markets.

This project will contribute to biomass gasification R&D. First, a unique comprehensive model for biomass particle gasification will be developed within a general particle framework and will be validated by experimental data available in the literature. Then, a detailed model-based parametric study will be performed to investigate the impacts of approximations, sub-models for various sub-processes, and more importantly gasification process conditions and feedstock properties. Finally, a reliable engineering model for biomass particle gasification which can be used in the practical scaling up, design and optimization of industrial biomass gasifiers will be developed.
