Progress in the preparation of biomass energy from steam-exploded lignocellulose

Steam explosion is an effective pretreatment method for the thermochemical conversion of biomass and an efficient way to produce sugars and fuels from lignocellulose. It breaks down the recalcitrant and complex structures in biomass, which are then converted into substances such as methane and fermentable sugars, and has great potential to mitigate global oil depletion and the threat of climate change. This review evaluates the effect of steam explosion temperature, dimension pressure time, and additive type factors on the pretreatment effect of the steam explosion method. The changes in the content and physical structure of the components in the treated biomass are also explored. The advantages and disadvantages of this means for the subsequent process and its application in industrial production are analyzed in depth to provide technical reference for steam explosion in the preparation of biomass from lignocellulose.
