Abstract
PURPOSE: To improve the decomposability of a biomass with cellulase, by cutting and crushing the biomass to specific size, and cooking in a specific amount of an aqueous solution of alkali and alkali sulfide.
CONSTITUTION: The biomass such as bagasse, beech wood, white birch wood, corncob, etc. is cut and crushed to 10W150mesh, and cooked in an aqueous solution of an alkali and an alkali sulfide. The amount of the solution is 4W10pts.wt. per 1 pt. of the biomass, the weight ratio of alkali to biomass is 9W30%, and that of alkali sulfide to biomass is 3W15%. The alkali is KOH, NaOH, or NH3, and the alkali sulfide is e.g. Na2S, K2S, KHS, (NH4)2S, etc. The cooking is carried out at 90W210°C for 0.25W5hr.
