Biomass to Hydrogen-Rich Syngas and Liquid Fuels through Thermochemical Processing
Biomass gasification and pyrolysis have recently attracted great interests for development of sustainable bioenergy and liquid biofuels. This presentation will firstly provide an overview on the latest research and development projects overseas on the biomass gasification and biomass pyrolysis. Then the research projects and achievements at University of Canterbury, New Zealand, will be discussed in more details. The key issues in commercialization of biomass conversion technologies have been recognized as costs, conversion efficiency and environmental impacts. Therefore, extensive research has been conducted to reduce the costs, increase the conversion efficiency and reduce the negative environmental impacts. The research program undertaken at University of Canterbury has been focusing on development of a new gasification technology, called fast internal circulating fluidized bed (FICFB) gasifier with steam as gasification agent. So far, clean and hydrogen-rich syngas has been produced with the hydrogen content being up to 40％ (vol.). With this gasification technology, optimum CO to H2 ratio of 2 has been achieved for Fischer-Tropsch (F-T) synthesis of liquid fuel thus the research is also conducted to develop micro-channel F-T reactors and F-T catalyst. To reduce the transportation costs of widely distributed and low density biomass, co-gasification of biomass with coal and densification of the biomass by pyrolysis for gasification are being investigated. To improve the gasifier design and optimize the gasification operation, a cold transparent gasifier model has also been constructed and used for study of flow hydrodynamics in the FICFB gasifier.
