Mechanical Pretreatment of Biomass
Background
Lignocellulosic Biomass
Lignocellulosic biomass is defined as a plant, or plant-derived, material that is mostly composed of cellulose, hemicellulose, and lignin. Lignocellulosic feedstocks are highly abundant, covering many biomass types including grasses, wood, energy crops (e.g. Miscanthus and coppices), agricultural residues (e.g. straws and corn stover), and municipal wastes.Lignocellulosic feedstocks are highly abundant and can often be sourced sustainably, at low cost, without leading to land-use conflicts. As a result, there is currently great interest in obtaining chemicals, fuels, and biomaterials from such biomass.
A major pathway by which many lignocellulosic feedstocks are processed is known as hydrolysis,
where sugars are released
from the lignocellulosic polysaccharides (i.e. cellulose and hemicellulose).
However, the hydrolysis of lignocellulosic polysaccharides is not easy and is influenced by the complex inter-associations between hemicellulose and cellulose and between these polysaccharides and lignin in the lignocellulosic matrix. In particular, the crystalline nature of much cellulose and the existence of a physical barrier of lignin surrounding the cellulose fibres are said to be major contributors to the recalcitrance of cellulose.
The mechanism of hydrolysis is further complicated by the fact that different process intensities are required for the hydrolysis of cellulose versus hemicellulose. The more intense conditions required for cellulose hydrolysis may degrade the sugars hydrolysed from hemicellulose (to products such as furfural and formic acid).
For this reason, most hydrolysis technologies employ pre-treatment processes that aim to break apart the matrix (and in particular the associations between lignin and cellulose), reduce cellulose crystallinty, and hydrolyse hemicelluloses, hence separating the hydrolysate from cellulose which can then undergo more severe/targeted treatment.

Mechanical Pretreatment of Biomass
Mechanical pretreatment is used to reduce the particle size for ease of handling and increased surface/volume ratio.
This can be done by chipping, milling, or grinding.
It is generally the case that the smaller the particle size, the higher the efficiency of the process. However, excessive reduction in particle size may cause process issues (e.g. viscosity, high water holding, filter clogging etc.).
Depending on the pretreatment conditions, and on the particle-size reduction tools used in the process, the pretreatment process may also cause the biomass to shear and reduce the degree of polymerization, which in turn increases the available accessible area to chemicals, enzymes and microbes.

Other Types of Biomass Pretreament
Steam pretreatment uses high-pressure steam at elevated temperatures. In steam-explosion pretreatment this is followed by
rapid decompression which physically disrupts the biomass structure.

Hydrothermal pretreatment, also know as Liquid Hot Water (LHW) pretreatment,
does not involve the use of any chemicals but operates at elevated temperatures and pressures

This pretreatment involves treating the biomass with a dilute solution of a strong acid at elevated temperatures. A primary
target is the hydrolysis of hemicellulose into monomeric sugars.

Alkali pretreatment uses
chemicals (e.g. sodium hydroxide, potassium hydroxide, calcium hydroxide) to disrupt the complex structure of lignocellulosic
biomass with lignin removal a primary target.

Organosolv pretreatment fractionates biomass into its three major
components (cellulose, hemicellulose, and lignin), with obtaining a lignin of a high-purity and quality being
a particular target.
