文摘

Rapeseed was treated by hydrothermal/dilute-acid at different temperature ranges. The effect of temperature on glucose yield and structure was evaluated. High temperature resulted in substantial changes of rapeseed straw structure. Delignification with pretreatments greatly reduced the biomass recalcitrance. A two-step treatment efficiently separated cellulose, hemicelluloses and lignin.
