Biomass utilization for bio-energy, bio-fuels or bio-based products requires reduction of the material size within specific ranges depending on feedstock specie, handling and further processing / conversion processes. Biomass size reduction is a mechanical treatment process that refers to either cutting or comminuting processes that significantly change the particles size, shape and bulk densit...

The innovative study was carried out to produce nano-cellulose based bioplastic biomaterials for vehicle use coming after bioprocess technology. The data show that nano-cellulose particle size was 20 nm and negligible water absorption was 0.03% in the bioplastic. Moreover, burning test, size and shape characterizations, spray coating dye, energy test and firmness of bioplastic have been explore...

The aerodynamic behavior of wet forestry biomass particles mechanically shaken in a fluidized bed was analyzed with turning velocity between 0.5 and 2 r.p.s. It was concluded that the agitation exerts an important effect on the fluidization of wet biomass particles. The effect of the agitator is not relevant if the particles have low humidity content. In addition, a methodology based on the Erg...

Understanding the energy requirement for biomass size reduction would be very significant for the process of converting the biomass to bioenergy. A hammermill was used for size reduction operations. One 12.7 mm size screen was applied to hammer mill for different particle size reduction. Torque Sensor was connected to the engine shaft to measure the transfer of torque and engine rotational spee...

This research aimed at measuring the electrical capacitance of miscanthus biomass as a potential proxy measure of bulk density. The experimental arrangement allowed for continuous variation of bulk density through compression, whereas moisture content was varied at two levels, being air-dried (<5%) and oven dried (14.5%), and particle size was varied by using material that passed milling screen...

Three lignocellulosic pretreatment techniques (ammonia fiber expansion, dilute acid and ionic liquid) are compared with respect to saccharification efficiency, particle size and biomass composition. In particular, the effects of switchgrass particle size (32-200) on each pretreatment regime are examined. Physical properties of untreated and pretreated samples are characterized using crystallini...

In this study bulk airborne aerosol composition measured by the PILS-IC (integration time of 3 min 24 s) during TRACE-P P3B Flight 10 are used to investigate the ionic chemical composition and mixing state of biomass burning particles. A biomass burning plume, roughly 3– 4 days old, moderately influenced by urban pollution aerosols recorded in the Philippine Sea is investigated. Focusing on the...

[1] Aircraft-based measurements of aerosol composition, either bulk or single-particle, and both subsaturated and supersaturated hygroscopicity were made in the Los Angeles Basin and its outflows during May 2010 during the CalNex field study. Aerosol composition evolves from source-rich areas in the western Basin to downwind sites in the eastern Basin, evidenced by transition from an external t...

BACKGROUND It is widely believed that reducing the lignocellulosic biomass particle size would improve the biomass digestibility by increasing the total surface area and eliminating mass and heat transfer limitation during hydrolysis reactions. However, past studies demonstrate that particle size influences biomass digestibility to a limited extent. Thus, this paper studies the effect of partic...

Size reduction is the first step for manufacturing biofuels from woody biomass. It is usually performed using milling machines and the particle size is controlled by the size of the sieve installed on a milling machine. There are reported studies about the effects of sieve size on energy consumption in milling of woody biomass. These studies show that energy consumption increased dramatically a...
