The orthogonal L9 (3)4 method was used to analyze the effect of a few processing parameters on crystallinity of pretreated miscanthus. The optimal conditions were: the miscanthus concentration was 30mg per gram of solvent, the temperature and time for dissolution were 120°C and 2 h respectively, and aqueous K3PO4 was used for precipitation. For these optimal conditions, the crystallinity index is about 41%, significantly lower than that of new miscanthus whose crystallinity index is 64%. A decrease in crystallinity favors efficient hydrolysis of cellulose to sugars that can be fermented to ethanol.
