Mechanical Pretreatment of Lignocellulosic Biomass for
Lignocellulosic biomass (LB) sources which are readily available in abundance are widely considered as a potential future sustainable raw materials for biofuel production. Typically, biofuel production involved several chemical and mechanical steps consisting of pretreatment, hydrolysis, fermentation and separation. The pretreatment step is considered as one of the most vital part of the whole

Conversion of Lignocellulosic Biomass into Liquid DropIn
Biomass particle size can be much larger than required for conventional pyolysis methods, thus reducing the time and energy cost of initially grinding the biomass into very small particles prior to the thermo chemical processing. Heat transfer is also very energy efficient.

US20160369305A1 Process for dry fractionation of
The process for the dry fractionation of lignocellulosic biomass of at least 50% by weight of lignins, cellulose and hemicelluloses. The biomass is fragmented to obtain an ultrafine powder. The process includes at least one step of separating a fraction enriched with cellulose and a fraction enriched with lignin, hemicelluloses and minerals by electrostatic sorting of the ultrafine particles.

Understanding the Impact of Lignocellulosic Biomass
The importance of size reduction to the commercial deployment of biomass utilization technologies cannot be overemphasized. Size reduction is necessary to create good flowing, easily digestible lignocellulosic biomass. However, inefficiencies and inconsistencies have not been well addressed for the process of size reduction. This has motivated quite a few research studies, some of which have
