Abstract

Mechanical milling of biomass as a pretreatment to render the biomass readily saccharifiable requires high energy input. Preceding mechanical milling by treatment with anhydrous ammonia was found to greatly reduce the energy requirement for fine milling, providing a more economical pretreatment process for commercial use.
