| Abstract
| - Gasification is one of the promising technologies for thermochemical conversion of biomass. Biomassgasification using high-temperature air/steam has many features superior to those of conventional gasificationusing low-temperature gases. To improve the conversion efficiency, it is important to understand transportphenomena in biomass gasification and optimize the packaging of biomass before its use in industry. A novelmodeling tool has been developed to study biomass gasification process, and it consists of a system-levelmodel and a pore-level model. Effects of feedstock packaging such as initial porosity, particle size, anddistribution on the gasification rate will be investigated. The concept to design holes in the feedstock isproposed to increase the gasification rate. It is revealed that optimizing the size of the holes in the packedbiomass can increase the biomass gasification rate significantly.
