摘要

来自木质素基生物质热解的生物油通常含有各种含氧化合物，这可能会损害其作为燃料的用途。为了提高生物油的质量，催化加氢脱氧(HDO)是将油中的氧气以水的形式去除的关键步骤。在这项研究中，我们证明了MFI纳米片是钌催化剂的良好载体。我们使用简单的水热播种程序合成了高结晶的MFI纳米片;结晶56 h后得到最终材料。考察了钌在不同载体上的活性。我们的研究结果表明，分级MFI支持的Ru对愈创木酚的HDO具有良好的活性。结果表明，Ru/ZNS-56在温和条件下(200°C, 50 bar H2, 1 h)对环己烷的选择性接近100%。

Selective Hydrodeoxygenation of Guaiacol to Cyclohexane over Ru-Catalysts Based on MFI Nanosheets

Bio-oils derived from the pyrolysis of lignin-based biomass often contain a variety of oxygenated compounds, which can compromise their usefulness as a fuel. To improve the quality of bio-oil, catalytic hydrodeoxygenation (HDO) is a crucial step that removes oxygen from the oil in the form of water. In this study, we showed that MFI nanosheets are excellent supports for Ru-catalysts. We synthesized highly crystalline MFI nanosheets using a simple hydrothermal seeding procedure; the final material was obtained in 56 h of crystallization. We investigated the activity of Ru supported on different materials. Our findings indicated that Ru supported on hierarchical MFI demonstrated excellent activity in HDO of guaiacol. Our results demonstrated that Ru/ZNS-56 achieved nearly 100% selectivity towards cyclohexane under mild conditions (200 °C, 50 bar H2, 1 h).
