Mango fruit seed shells were used as starting materials to produce activated carbons for the capture of acetone, a typical volatile organic compound (VOC), from gaseous streams. This fruit waste presents high volatiles and low ashes contents, as expected for the lignocelulosic materials commonly used for the preparation of activated carbons. The starting material was hydrothermally treated at 180 or 250 °C for 5 h and the obtained hydrochars were activated with KOH solutions. The carbon samples were characterized by SEM, EDX, TG/DTA, Raman spectroscopy and textural analysis by physisorption. The adsorption capacity and adsorption cycles were investigated by TG. The hydrochars presented spherical morphology and the activated carbons derived from them presented heterogeneous micropore structures allowing to high capacity of acetone vapor removal, namely 472 mg/g, at 30 °C and 363 mg/g, at 50 °C. The results indicate that the adsorption capacity of the activated carbons is directly related to their Dubinin-Astakhov micropore surface areas and microporous volumes determined by NLDFT. The adsorption of acetone vapor showed a pseudo-first order kinetics and both external and intra-particle transport contributed for the overall process. Highly efficient and stable acetone vapor removal was observed over the activated carbons after five cycles.

芒果果实的种子壳被用作生产活性炭的原料，用于从气流中捕获丙酮，丙酮是一种典型的挥发性有机化合物（VOC）。如通常用于制备活性炭的木质纤维素材料所预期的那样，这种果渣具有高挥发性和低灰分含量。将起始材料在180或250°C进行水热处理5 h，然后将获得的烃用KOH溶液活化。碳样品通过SEM，EDX，TG / DTA，拉曼光谱和物理吸附进行结构分析。TG研究了其吸附容量和吸附循环。碳氢化合物呈现球形形态，从碳氢化合物衍生的活性炭呈现非均质的微孔结构，从而可高效去除丙酮蒸气，即在30°C下为472 mg / g，在50°C下为363 mg / g。结果表明，活性炭的吸附能力与它们的Dubinin-Astakhov微孔表面积和NLDFT测定的微孔体积直接相关。丙酮蒸气的吸附表现出拟一级反应动力学，外部和内部颗粒传输对整个过程都有贡献。在五个循环后，在活性炭上观察到高效，稳定的丙酮蒸气去除。丙酮蒸气的吸附表现出拟一级反应动力学，外部和内部颗粒传输对整个过程都有贡献。在五个循环后，在活性炭上观察到高效，稳定的丙酮蒸气去除。丙酮蒸气的吸附表现出拟一级反应动力学，外部和内部颗粒传输对整个过程都有贡献。在五个循环后，在活性炭上观察到高效，稳定的丙酮蒸气去除。
