Abstract
5 wt% ruthenium-loaded Zeolite-β is found to be efficient for hydrotreating the lignin model compound, m-cresol, at 170 °C under 10 bar hydrogen pressure to give methyl cyclohexane. The catalyst has a bifunctional nature in which the redox properties of ruthenium and the strong acidic nature of Zeolite-β are instrumental in the hydrotreating of m-cresol. The well-dispersed metallic ruthenium on Zeolite-β, as evident from TEM and EDS mapping analysis, is responsible for the potential activity. The activity was retained even after six cycles and was also found to have potential for hydrotreating various other functional substrates.
研究发现，5 wt% 的钌负载沸石-β 能在 170 °C 和 10 bar 氢压条件下高效加氢处理木质素模型化合物，生成甲基环己烷。该催化剂具有双功能特性，其中钌的氧化还原特性和沸石-β的强酸性在加氢处理-甲酚中发挥了重要作用。从 TEM 和 EDS 图谱分析中可以看出，金属钌在沸石-β 上的良好分散是产生潜在活性的原因。这种活性即使在六个周期后仍能保持，而且还被发现具有加氢处理各种其他功能基质的潜力。
