摘要: Abstract The purpose of this study was to investigate the effects inorganic species in biomass, especially alkali and alkaline earth metallic (AAEM) (K, Na, Mg Ca), on yield properties bio-oil from pyrolysis biomass. A mallee wood sample Western Australia washed with water a dilute acid solution remove its AAEM species. water-washed acid-washed samples were then pyrolysed fluidised-bed reactor at 500 °C under fast heating rate conditions. removal did not result significant changes yields bio-char. However, properties, e.g. viscosity, drastically affected by Our results indicate that water-soluble as important water-insoluble but acid-soluble influencing composition properties. It is believed (especially Ca) more closely linked organic matter biomass thus involved reactions during pyrolysis. species, led very increases sugars lignin-derived oligomers, accompanied decreases light compounds bio-oil.
