Pretreatment is required for the enhancement of the bioconversion of lignocellulosic biomass. This study aimed to develop an integrated process producing efficient biochemical conversion of rubber wood waste (RW) into co-biofuels, fermentable sugar and methane. The glucan conversion was enhanced to 93.8% with temperature (210 °C) and delignification by organosolv pretreatment (OS). Thereafter, anaerobic digestion of the residue left after enzymatic hydrolysis was conducted which further improved the methane yield (205.5 LCH/kg VS) by 33% over hydrothermal pretreatment (154.3 LCH/kg VS). Delignification during OS plays a key role in improving the degradability of RW resulting in efficient energy recovery (11.23 MJ/kg pretreated RW) which was clearly higher than an integrated process based on hydrothermal (HT) or HT plus process water. Scaled up to a biorefinery, the integrated process based on OS would economically produce fermentable sugar while other value-added chemicals might be produced from the process water.

从橡胶木生产可发酵糖和甲烷的综合工艺



需要预处理来增强木质纤维素生物质的生物转化。本研究旨在开发一种集成工艺,将橡胶木废料 (RW) 高效生化转化为辅助生物燃料、可发酵糖和甲烷。随着温度 (210 °C) 和有机溶剂预处理 (OS) 的脱木质素作用,葡聚糖转化率提高至 93.8%。此后,对酶解后留下的残渣进行厌氧消化,与水热预处理(154.3 LCH/kg VS)相比,甲烷产率(205.5 LCH/kg VS)进一步提高了33%。 OS 期间的脱木质素在提高 RW 的降解性方面发挥着关键作用,从而实现高效的能量回收(11.23 MJ/kg 预处理的 RW),这明显高于基于水热 (HT) 或 HT 加工艺水的集成工艺。如果扩大到生物精炼厂,基于操作系统的集成工艺将经济地生产可发酵糖,同时可以从工艺用水生产其他增值化学品。
