The essential amino acid lysine is of great importance in the nutrition and pharmaceutical industries and is mainly produced in biorefineries by the fermentation of glucose. In biorefineries, downstream processing is often the most energy‐consuming step. Adsorption on hydrophobic adsorbents represents an energy, resource, and cost‐saving alternative. The results reported herein provide insights into the selective separation of l ‐lysine from aqueous solution by liquid‐phase adsorption using tailored activated carbons. A variety of commercial activated carbons with different textural properties and surface functionalities is investigated. Comprehensive adsorbent characterization establishes structure–adsorption relationships that define the major roles of the specific surface area and oxygen functionalities. A 13‐fold increase of the separation of lysine and glucose is achieved through systematic modification of a selected activated carbon by oxidation, and lysine adsorption is enhanced by 30 %.

为有效的下游工艺量身定制活性炭：赖氨酸的选择性液相吸附。

必需氨基酸赖氨酸在营养和制药工业中非常重要，主要在生物精炼厂中通过葡萄糖的发酵生产。在生物精炼厂，下游加工通常是最耗能的步骤。在疏水性吸附剂上的吸附代表了一种能源，资源和节省成本的选择。本文报道的结果提供了对I的选择性分离的见解使用量身定制的活性炭，通过液相吸附从水溶液中提取赖氨酸。研究了具有不同质地特性和表面功能的各种商业活性炭。全面的吸附剂表征建立了结构-吸附关系，该关系定义了比表面积和氧官能度的主要作用。赖氨酸和葡萄糖的分离度通过氧化选择性修饰活性炭而实现了13倍的增加，赖氨酸的吸附提高了30％。
