Leaching of inorganic and organic matter from biomass and biochars under various conditions: equilibrium, kinetics and implications
MetadataShow full item record
This thesis investigates into the leaching phenomena in various biomass thermochemical processes. For biomass water leaching, the leachate is acidic and can interact with biomass. A method has therefore been devised for quantifying water-soluble inorganic species in biomass. For biochar leaching, partial steam gasification of biochar at low conversions is a good strategy to facilitate nutrients recycling. For biomass leaching in hot-compressed water, substantial leaching of inorganic species takes place during the hydrolysis of saccharides.

Leaching Characteristics of Organic and Inorganic Matter from Biomass by Water: Differences between Batch and Semi-continuous OperationsLiaw, Sui Boon; Wu, Hongwei (2013)Over 30% and ~2% (on a carbon basis) organic matter can be leached from mallee leaf and wood by water, respectively, producing acidic leachates containing organic acids. As a result, there are significant differences in ...
Yip, Kong; Li, Chun-Zhu; Wu, Hongwei (2010)This study reports the removal of inorganic species by water leaching from a Western Australia mallee biomass and its biochars. The study focuses on the removal of AAEM species (Na, K, Ca and Mg) and other nutrient elements ...
Removal and Recycling of Inherent Inorganic Nutrient Species in Mallee Biomass and Derived Biochars by Water LeachingWu, Hongwei; Yip, Kong; Kong, Zhaoying; Li, Chun-Zhu; Liu, Dawei; Yu, Yun; Gao, Xiangpeng (2011)Biomass growth extracts inorganic nutrients from soil as inherent nutrient species in the biomass. Unless at least some of these inherent inorganic nutrients are eventually recycled to the soil, biomass utilization during ...
