Victoria has abundant brown coal resource, but they are mainly used for mine-mouth power generation units with very low efficiency and high greenhouse gas emissions. Entrained flow gasification is a technology with great potential for Victorian brown coal utilization to produce high-value products. However, little is known about entrained flow gasification of Victorian brown coal. Therefore, the major objective of this study is to obtain a better understanding of entrained flow gasification of Victorian brown coal with CO2 using different experimental and modelling approaches. The focus of this research is to examine:
1) the effect of a wide range of operational variables on gasification performance and emission of air pollutants,
2) the mineral transformation during coal pyrolysis and char gasification,
3) a comparison of entrained flow gasification behaviour of Victorian brown coal and biomass,
4) the kinetic modelling of char-CO2 gasification of Victorian brown coal.
