以介孔硅SBA-15为模板,焦糖和呋喃醇为碳源,通过多种浇注法制备介孔炭材料.采用低温氮吸附、透射电镜和X射线小角衍射分析模板及介孔炭的织构.结果显示合成的介孔炭成功地复制了SBA-15的结构.以制备的介孔炭作载体担载钴钼合成了加氢脱硫催化剂,利用X射线能谱、透射电镜能量分布谱及一氧化氮化学吸附评估了催化剂的活性及活性点分布,结果表明介孔炭担载的催化剂活性高于活性炭担载的同类催化剂.

A range of mesoporous carbons as potential supports to enhance ultra-deep hydrodesulphurization (HDS) of diesel fuel was synthesized using a sol-gel method. SBA-15 was used as template and sucrose and furfuryl alcohol were used as carbon sources. Various carbon incorporation approaches were used. From the results of nitrogen adsorption, transmission electron microscopy and X-ray diffraction, the synthesized carbon exhibited good replication of the SBA-15 structure. Loading of Co-Mo into the mesoporous carbons and catalysis dispersion were evaluated using various techniques including X-ray photoelectron spectroscopy and energy dispersive X-ray analysis. The intrinsic HDS activity was evaluated by NO chemisorption on the prepared catalysts, which showed that the catalyst supported on mesoporous carbon using sucrose as carbon precursor has a higher NO uptake than that supported on commercial activated carbon.
