Lignocellulosic biomass is considered as the future feedstock for ethanol production because of its low cost and its huge availability. One of the major lignocellulosic materials found in great quantities to be considered, especially in tropical countries, is sugarcane bagasse (SCB). This work deals with its current and potential transformation to sugars and ethanol, considering pretreatment technologies, detoxification methods and biological transformation. Some modeling aspects are exposed briefly. Finally stability is discussed for considering the high nonlinear phenomena such as multiplicity and oscillations, which make more complex the control as a result of the inhibition problems during fermentation when furfural and formic acid from SCB hydrolysis are not absent.
木质纤维素生物质被认为是未来生产乙醇的原料,因为它成本低、来源广泛。在大量被考虑的主要木质纤维素材料中,甘蔗渣(SCB)是一种尤其受到关注的材料,特别是在热带国家。本文主要考虑了 SCB 转化为糖和乙醇的现状和潜力,探讨了预处理技术、解毒方法和生物转化。本文还简要介绍了一些建模方面的内容。最后,本文还讨论了稳定性问题,因为高非线性现象(如多重性和振荡)会使发酵过程中的抑制问题更加复杂,从而使控制变得更加复杂,而发酵过程中不可避免会出现 SCB 水解产生的糠醛和甲酸。
