Abstract
Steam Explosion (SE) is one of the most efficient and environmentally friendly processes for the pretreatment of lignocellulosic biomass. It is an important tool for the development of the biorefinery concept to mitigate the recalcitrance of biomass. However, the two distinct steps of SE, steam cracking and explosive decompression, leading to the breakdown of the lignocellulosic matrix have generally been studied in empiric ways and clarification are needed. This mini-review provides new insights and recommendations regarding the properties of subcritical water, process modeling and the importance of the depressurization rate.
Highlights
The 21st century is witnessing the emergence of a new industry based on lignocellulosic biomass refining
The results showed that the steam explosion process requires 70% less energy to achieve the same size reduction as the mechanical method (Holtzapple et al, 1989)
Steam Explosion (SE), which is a combination of a sub-critical water treatment and a cell wall disruption, has been extensively described as a pretreatment for the production of fermentable sugars
