Biomass conversion technologies including direct combustion, thermo-chemical conversation and biological conversion technologies will be introduced. For fast pyrolysis technology, rice husks were pyrolyzed in a 1-5 kg/h bench-scale fluidized-bed reactor. The effect of hot vapor filtration (HVF) was investigated to filter the solid particles and biochar. The results showed that the total bio-oil yield decreased from 41.7 wt.% to 39.5 wt. % by weight and the bio-oil had a higher water content, higher pH, and lower alkali metal content when using HVF. One hundred and twelve different chemical compounds were detected by gas chromatography-mass spectrometry (GC-MS).In addition, pine sawdust was pyrolyzed in order to investigate the effects of selective condensation on bio-oil characterization. The results showed that the total bio-oil, the gases and the char yields were 41.5 wt.%, 43.3 wt.%, 15.2 wt.% respectively and 86.2 wt. % water steam was condensed in condenser 1. Furthermore, a commercial-scale biomass fast pyrolysis plant with biomass throughput of 1-3 T h^-1 has been developed for bio-oil production and its performance has been investigated. For biogas technology, biogas production from undiluted chicken manure and maize silage: A study of ammonia inhibition in high solids anaerobic digestion is introduced. Impacts of alkaline hydrogen peroxide pretreatment on chemical composition and biochemical methane potential of agricultural crop stalks is given.
