抄録

A fundamental investigation on the extraction from biomass, low rank coal and their mixture during hydrothermal treatment was conducted by using a circulative equipment having a 10 cm3 cell. Beluga coal from Alaska, and Cryptomeria Japonica and empty fruit bunch of oil palm (EFB) were used as material samples of low rank coal and biomass, respectively. Biomass started to be decomposed at a temperature lower than that of low rank coal, which suggests that amorphous cellulose and hemicellulose were hydrolyzed. Frans such as furfural and 5-hydroxymethyl-2-furaldehyde (HMF) extracted from biomass were unstable as compared to phenol, and therefore decomposed and partially cyclized. It was considered that low rank coal adsorbed extracts from biomass due to the porous morphology. The possibility to predict the TOC from an on-line monitoring of the absorbance intensity in UV region during hydrothermal treatment was also shown.
