Hydrothermal reaction of glucose and glycine as model compounds of biomass

Abstract

Glucose and glucine as model compounds of biomass were reacted in hot-compressed water at 150°-350°C. The product distribution as gas, char, oil, and aqueous products was examined based on the reaction temperature. The Maillard products, melanoidin, were decomposed over 200°C to produce the char, gas, ammonia, and decomposed products in aqueous solution. The char was formed in the low reaction temperature range 150°-200°C, while the oil was formed at > 250°C. The overall reaction scheme was proposed.
