Abstract
A basic study on auto-hydrolysis, i. e. saccharification, of wood biomass by using micro-wave irradiation was carried out for efficiently utilizing unusable wood biomass such as the waste produced in wood sawing process. As the result, the following information was obtained especially on heating temperature, irradiation time and particle diameter of wood powder.
(1) It was necessary for efficient saccharification to heat the powder over 160°C by using micro-wave irradiation.
(2) Heating time for efficient saccharification depended on the particle diameter of the powder, and heating time should be designed on the basis of the particle diameter.
(3) Irradiation energy for producing sugar stabilized at the lower value by heating over 180°C.
