Abstract: Biomass gasification is an efficient and environmentally friendly technology to realize energy conversion from biomass. In the first work, a coupled representative particle and fuel-bed model was developed to predict the production rate and quality of both syngas and biochar. Energy and economic evaluation have been conducted. The second study proposed a hybrid municipal solid wastes disposal process. Maximum energy efficiency could reach 70.72% by co-gasifying 80wt% wood chips and 20wt% AD residue with 30% moisture content. In the third work, we characterized the particulate emission of the gasification and pyrolysis process. A particle respiratory deposition-based cyclone design scheme was proposed. The cyclone collection efficiency was found to be most sensitive to the vortex finder diameter. The last work involved the characterization of particulate emission at three emission hotspots in Singapore. Respiratory deposition models were employed to analyse the deposition distributions of particles and their impacts on human respiratory system.
