Hydrothermal liquefaction conversion of lignocelluloses with enhanced fungal pretreatment

Although it is considered to be an environmental-friendly approach reduce recalcitrance of lignocellulosic biomass, current fungal pretreatment methods suffer from major weaknesses, including inefficient delignification, loss cellulose, and the need for long processing time. The addition Mn white-rot treatment process could facilitate selective removal lignin. However, effect on thermal decomposition conversion fungi-pretreated biomass not clear. In this study, three types lignocelluloses (poplar, wheat straw, corn stover) were pretreated with fungi that was cultured supplements. Results demonstrated affected thermogravimetric properties, as well lignin hemicellulose contents. poplar samples showed highest delignification (50.5 %) lowest cellulose (1.1 %). initial degradation temperatures lowered by 11–36 ?, measured analysis. Additionally, feedstocks converted in a two-stage hydrothermal liquefaction produce hydrolyzed sugars value-added derivatives stepwise manner. A 163.6 % more recovered compared untreated samples, while 75.2 sugar production achieved first stage fungi-treated stover addition. Pretreating includes supplements significantly improved production. Thus, combination subsequent thermochemical offers promising alternative technical route valorization.
