As a step toward developing an energy-saving, low-cost process to produce fuel-grade ethanol from cellulosic biomass through chemical pre-treatment, bagasse was treated with various chemicals under different conditioins. Alkalis, acids, alcohol-alkali mixtures, alcohol-acid mixtures, sodium sulfide-caustic soda mixture, peracids, and sulfurous acid were used for pre-treatment, and the residual solid, rate of lignin removal, enzymatic saccharification rate, enzymatic decomposition rate, and crystallinity of the pretreated bagasse were measured, along with the raw bagasse saccharification rate for comparison. Good results were obtained by the pre-treatmen with alkali, alcohol-alkali mixtures and Na_2S-NaOH mixture. The Na_2S-NaOH mixture treatment merits further development regarding its scale up.
