Abstract

The paper describes an investigation into hydrogenation of furfural over ruthenium catalysts supported on porous aromatic frameworks. The supports were designated as PAF-30-SO₃H, PAF-30-NH₂, and PAF-30. The synthesized catalysts were tested in furfural hydrogenation carried out in water and in tetrahydrofuran (with a concentration of 10 wt %) at 90–250°C and a hydrogen pressure of 3 MPa. Although the highest furfural conversion (96%) was achieved in the case of its hydrogenation in water at 250°C over Ru-PAF-30, these conditions did not favor product selectivity. The reaction products mainly consisted of furfuryl alcohol, tetrahydrofurfuryl alcohol, and cyclopentanone. The highest yield of cyclopentanone, 71% (with 80% conversion and 89% selectivity) was observed in furfural hydrogenation over Ru-PAF-30 at 200°C, whereas the conditions optimal for selective hydrogenation of furfural into furfuryl alcohol were found to include either tetrahydrofuran as a solvent or water as a solvent and low temperatures (90–150°C).

多孔芳香族框架支撑的钌催化剂上的糠醛加氢反应

本文介绍了在多孔芳香框架支撑的钌催化剂上进行糠醛加氢的研究。这些支撑物被命名为 PAF-30-SO3H、PAF-30-NH2 和 PAF-30。合成的催化剂在水和四氢呋喃（浓度为 10 wt%）中进行了糠醛加氢试验，试验温度为 90-250°C，氢气压力为 3 兆帕。虽然在 Ru-PAF-30 的作用下于 250°C 水中进行的糠醛氢化反应中，糠醛的转化率最高（96%），但这些条件并不利于产品的选择性。反应产物主要包括糠醇、四氢糠醇和环戊酮。在 Ru-PAF-30 上进行糠醛氢化时，温度为 200°C，环戊酮的产量最高，为 71%（转化率为 80%，选择性为 89%），而糠醛选择性氢化为糠醇的最佳条件是以四氢呋喃为溶剂或以水为溶剂，温度较低（90-150°C）。

期刊介绍： Petroleum Chemistry (Neftekhimiya), founded in 1961, offers original papers on and reviews of theoretical and experimental studies concerned with current problems of petroleum chemistry and processing such as chemical composition of crude oils and natural gas liquids; petroleum refining (cracking, hydrocracking, and catalytic reforming); catalysts for petrochemical processes (hydrogenation, isomerization, oxidation, hydroformylation, etc.); activation and catalytic transformation of hydrocarbons and other components of petroleum, natural gas, and other complex organic mixtures; new petrochemicals including lubricants and additives; environmental problems; and information on scientific meetings relevant to these areas. Petroleum Chemistry publishes articles on these topics from members of the scientific community of the former Soviet Union.
