Kim, Seong Ju; Um, Byung Hwan published the artcile< Effect of thermochemically fractionation before hydrothermal liquefaction of herbaceous biomass on biocrude characteristics>, Formula: C4H8O3, the main research area is Miscanthus kenaf phenol hydrothermal liquefaction high performance liquid chromatog.
Hydrothermal liquefaction (HTL) of fractionated two types herbaceous biomass (kenaf and miscanthus) by dilute acid, organosolv, alk., or demineralization process was carried out under ethanol water co-solvent at 350°C for 30 min to examine the biocrude yield and characteristics. The biocrude properties were comprehensively characterized by HPLC, elemental, GC-MS, and TGA anal. Fractionation technologies before HTL effectively increased biocrude yield up to 38% compared to that of untreated herbaceous biomass (31%), except for organosolv fractionation of miscanthus, especially, HTL after alk. fractionation showed high yield and energy recovery ratio up to 70%. Elemental anal. showed that HHV of biocrude was neg. affected by hydrolysis reaction of high lignin content after dilute acid fractionation. The GC-MS anal. revealed that carbohydrates-derived compound significantly increased in the biocrude obtained after organosolv and alk. fractionation due to holocellulose increases through fractionation process. Addnl., TGA results indicated that the ratio of high-boiling-point compounds in biocrude obtained after demineralization was expanded compared with untreated due to ash removal, which could act as a catalyst.
