Green high-surface area Ordered Mesoporous Carbons (OMCs) (576–948 m/g) were successfully synthesized by the hard template method using xylose, glucose and lignin solutions obtained from almond shells, a local biomass waste, as carbon precursors, and SBA-15 as a template. The catalytic potential of OMCs, as catalytic supports or as catalysts, has been preliminarily tested for different reactions of interest. A dried sulfonic-acid treated OMC, obtained from xylose extract, led to full conversion and 92% selectivity to di- and tri-ethers of glycerol for the glycerol etherification with isobutene at 80 °C. A sulfonic-acid treated OMC, obtained from glucose, presented a higher turnover frequency (TOF) value and slightly lower selectivity to levulinic acid than commercial Amberlyst-15 for the conversion of 5-hydroxymethylfurfural at 180 °C. The use of an OMC obtained from lignin as catalytic support of a nickel catalyst combined with H-Beta led to 78% of selectivity to cyclohexane at total conversion for the hydrodeoxygenation of guaiacol at 180 °C.

从生物质衍生的木糖、葡萄糖和木质素中获得的绿色有序介孔碳的催化潜力

使用从当地生物质废物杏仁壳中获得的木糖、葡萄糖和木质素溶液作为碳前体和 SBA，通过硬模板法成功合成了绿色高表面积有序介孔碳 (OMC) (576–948 m/g) -15作为模板。 OMC 作为催化载体或催化剂的催化潜力已针对不同的感兴趣反应进行了初步测试。从木糖提取物中获得的经过干燥磺酸处理的 OMC，在 80 °C 下与异丁烯进行甘油醚化时，完全转化，生成甘油二醚和三醚的选择性为 92%。从葡萄糖中获得的经磺酸处理的 OMC 在 180 °C 下转化 5-羟甲基糠醛时，与商用 Amberlyst-15 相比，具有更高的转换频率 (TOF) 值和略低的乙酰丙酸选择性。使用从木质素获得的 OMC 作为镍催化剂的催化载体，与 H-Beta 结合使用，在 180 °C 愈创木酚加氢脱氧的总转化率下，环己烷的选择性为 78%。
