摘要：
Extracion of hemicelluloses from sugarcane bagasse under microwave radiation was studied in this paper. The effects of liquid to solid ratio ( V ( water) : in ( stover)), alkali consumption ( m( NaOH): m ( stover)), time, microwave power, and temperature on the extraction yield of hemicelluloses were investigated. The optimal parameters were: liquid to solid ratio of 25, alkali consumption of 2.0, time of 20 min, and microwave power of 1200 W. The obtained hemicelluloses was qualitatively analyzed by gas chromatography, and results showed that prepared hemicelluloses is a kind of xylan hemicelluloses, mainly consisting of simple sugars like D-xylose, D- arabinose, L- arabinose, D- galacturonic acid, D-galactose and D-mannose.
