| Research Abstract |
We developed the converge mill that applied large energy to produce strong mechanochemical effects. The one-liter batch type converge mill and the six-liter semi-continuous type converge mill were used to study converge milling (mechanochemical processing) and enzymatic saccharification properties of wood raw materials in order to achieve highly efficient milling for bioethanol production by the enzymatic saccharification method. The following conclusions have been reached as the result. (1) Regarding six-liter semi-continuous converge milling, the multistage pre-milling processes in combination of hammer milling and converge milling (complex dry mechanochemical milling) were efficient. (2) Ten-minute converge milling after hammer milling exhibited high saccharification performance and the milling energy required was lowest. In addition, 12 kg per day powder processing capacity and about 100 yen per liter unit cost for ethanol production (milling process) were achieved.
