Alkaline hydrogen pretreatment lignocellulosic biomass: Status, perspectives and energy policy

L
ignocellulosic biomass is a renewable and abundant resource suitable for the production of bio-based products such as
biofuels and chemicals. However, because of its complex chemical composition, requires a process that enhances the
release of sugars. Pre-treatment is an essential step to increase the efficiency of enzymatic hydrolysis of lignocellulosic biomass.
The most widely used pre-treatment methods operate at high temperatures (160-290°C) and pressures (0.69 to 4.9MPa) and
generate biological growth inhibitors such as furfural and hydroxymethylfurfural (HMF). Thus, the search for new approaches
to an effective pre-treatment that operates in ambient temperature and pressure and minimize the generation of inhibitors
was intensified. Among these methods, the alkaline hydrogen peroxide (AHP) has gained space because is effective for a wide
range of lignocellulosic biomass, enabling high enzymatic hydrolysis efficiency. However, little is discussed in major literature
reviews. Therefore, the aim of this study was to investigate the use of alkaline hydrogen peroxide (H

) as oxidative pre-
treatment agent to improve the efficiency of enzymatic hydrolysis for different types of biomass and discuss the key points of
the pre-treatment. Finally, the main challenges of this method for large-scale application are discussed. Also, for this talk, will
be discussed the historical evolution of regional Brazil and state energy policy support for and the currently attractive social
and economics of the production and use of ethanol from biomass.
