Feedstock logistics encompass all of the unit operations necessary to harvest or collect a renewable carbon source, such as biomass, and move it from the field or forest through to the throat of the conversion reactor at the biorefinery, while also ensuring that the delivered feedstock meets the specifications of the biorefinery conversion process (i.e., …
The total primary energy supply of biomass rose from 43.2 EJ 1 in 2000 to 54.9 EJ in 2011, which is a growth of 1 EJ/yr. In 2011, nearly half the world's population relied on biomass energy for cooking. Europe achieved the fastest growth of biomass for energy, reaching 1 EJ.The Americas were leading in the production of biofuels, …
Biomass preprocessing is one of the primary operations in the feedstock assembly system of a lignocellulosic biorefinery. Preprocessing is generally accomplished using industrial grinders to format biomass materials into a suitable biorefinery feedstock for conversion to ethanol and other bioproducts.

Predrying the feedstock is a common practice when the final product of interest is pyrolysis oil, which is either used directly for secondary heating applications or further catalytically upgraded to chemicals and fuels. 4.1 Density and Specific Gravity. Feedstock density plays an important role in commercial processes.
Terrestrial lignocellulosic biomass has the potential to be a carbon neutral and domestic source of fuels and chemicals. However, the innate variability of biomass resources, such as herbaceous and woody …
Storage of feedstock without appropriate control can lead to decomposition of the organic matter and lower biogas yields. Silage or ensiling is a common technique that preserves biomass by anaerobic fermentation to the point of acidification. ... Moreover, this also reduces cellulose crystallinity. Milling and grinding usually results in ...

the Stage-1 and Stage-2 grinding processes are influenced by process variables, such as biomass moisture content, screen size used in the grinder, grinder type, and feedstock type. According to Lopo [21], energy consumption of grinding biomass depends on initial particle size, moisture content,
Various pretreatments of biomass, such as drying, grinding, or chopping, are needed for this conversion process. This process leads to additional energy and cost, thereby delimiting the use of this technique. 8.5.1.5 Carbonization. Carbonization involves the production of carbon or carbon-rich residues from the organics in an exothermic …
