In this work, a sequential production of bioenergy platform intermediates (i. e., xylose and levulinic acid (LA)) and carbon materials from pine wood was developed by a three‐step conversion technology. Firstly, the hemicellulose in pine wood was hydrolyzed, obtaining 12.8 wt% xylose and 68.9 wt% solid products containing cellulose and lignin. Secondly, the solid products were hydrolyzed, obtaining 30.6 wt% LA and 42.0 wt% solid residues containing humins and lignin. Thirdly, the solid residues were used for activated carbon (AC) production through potassium hydrate (KOH) activation followed by pyrolysis from 400–800 ^oC. An AC obtained at a pyrolysis temperature of 800 ^oC had a high Brunauer‐Emmett‐Teller (BET) surface area of 2436 m²/g and pore volume of 0.91 cm³/g, which exhibited an excellent reactive brilliant red X‐3B (RBRX‐3B) adsorption capacity of 892 mg/g. As a case, 1000 g of pine wood finally produced 128 g xylose, 211 g LA and 39 g high‐performance activated carbon.

从松木中依次生产木糖，戊酸和活性炭

在这项工作中，通过三步转化技术开发了从松木中顺序生产生物能源平台中间体（即木糖和乙酰丙酸（LA））和碳材料的方法。首先，将松木中的半纤维素水解，得到12.8重量％的木糖和68.9重量％的含有纤维素和木质素的固体产物。其次，将固体产物水解，得到30.6重量％的LA和42.0重量％的含有腐殖质和木质素的固体残余物。第三，固体残留物用于通过水合钾（KOH）活化，然后在400–800 ^o C进行热解生产活性炭（AC）。在800 ^o C的热解温度下获得的AC具有较高的Brunauer-Emmett-Teller （BET）表面积2436 m ²/ g，孔体积为0.91 cm ³ / g，它具有892 mg / g的出色的活性艳红X-3B（RBRX-3B）吸附能力。最终，以1000克松木为例，产生了128克木糖，211克LA和39克高性能活性炭。
