    Abstract:

    Miscanthus floridulus biomass yield high, high photosynthetic efficiency, fast growth, easy breeding, widely distributed, is suitable as raw materials for the production of fuel ethanol. In this paper, the method of the pretreatment of liquid ammonia for Miscanthus floridulus, using the pretreatment of liquid ammonia to overcome biomass recalcitrance, adding cellulase enzyme, and the monosaccharide content is determined by using high performance liquid chromatography (HPLC). The experimental has a study of the conversion rate which is different growth period of Miscanthus floridulus of preparing cellulosic ethanol enzyme hydrolysis in cellulase dosage 15 FPU / (g eq dextran), the moisture content 100%, the pretreatment temperature 120°C, residence time 10 min, loading amount of ammonia 2:1. The data shows that, in optimal pretreatment conditions, September Miscanthus floridulus is in enzymolysis for 72 h, and the glucan and xylan enzyme conversion rates are 84.77% and 81.73% respectively. Dry base mans per 100 g can get fermentation monosaccharide 56.9g, 3.79 times than untreated. Considering the energy consumption, Miscanthus floridulus total sugar yield increase and the impact of biomass, the paper identifies September as Miscanthus floridulus best harvest.
