rst-generation ethanol production, C5 sugars, derived from the hemicellulosic fraction of the
A variety of biomass pretreatment technologies has been investigated; their main purpose is to modify or remove hemicellulose and/or lignin from the lignocellulosic matrix, further exposing cellulose ?
In this process, the lignocellulosic feedstock is submitted to steam treatment for a few minutes, followed by quick depressurization and cooling, during which hemicellulose is converted to pentoses (C5 sugars) through reactions catalyzed by acids released during pretreatment (autohydrolysis) or added to the reactor (Menon and Rao 2012; Pourbafrani et al. 2014).
(2011) Liquid hot water High hemicellulose solubility; no chemicals; high energy usage Yu et al
(2011a) Catalyzed steam explosion Short reaction time; high sugar yields; possible hemicellulose degradation Behera et al
