As the most abundant renewable carbon source, lignocellulose holds potential as a raw material for biofuels and biochar. The components required for biofuel production differ from those for biochar, so combining processes can reduce costs. Biofuel preparation necessitates cellulase treatment of lignocellulose. This study examines the effects of various enzyme treatment conditions (dosage, time, temperature) on lignocellulose, focusing on the properties of biochar derived from it (BC-SR). A mathematical model was constructed to study the relationship between enzyme treatment conditions and BC-SR properties. BC-SR exhibited high adsorption selectivity for bisphenol A and outperformed untreated biochar in fixed-bed column experiments, demonstrating greater removal efficiency and structural integrity. This study provides insights into the impact of enzymatic treatment on biochar and offers a cost-effective method for producing stable, efficient biochar. Additionally, a highly persistent biochar can enter the carbon trading market as a carbon-neutral technology, further realizing economic and environmental benefits.
作为最丰富的可再生碳源，木质纤维素有可能成为生物燃料和生物炭的原料。生物燃料生产所需的成分与生物炭不同，因此结合工艺可以降低成本。生物燃料制备需要木质纤维素的纤维素酶处理。本研究考察了各种酶处理条件（剂量、时间、温度）对木质纤维素的影响，重点研究了由此产生的生物炭（BC-SR）的特性。构建了一个数学模型来研究酶处理条件与 BC-SR 特性之间的关系。BC-SR 对双酚 A 表现出高吸附选择性，在固定床柱实验中优于未处理的生物炭，表现出更高的去除效率和结构完整性。本研究深入了解了酶处理对生物炭的影响，并提供了一种生产稳定、高效生物炭的经济有效方法。此外，高持久性生物炭可以作为碳中和技术进入碳交易市场，进一步实现经济和环境效益。
