With the aim of hydrogenating furfuryl alcohol into tetrahydrofurfuryl alcohol by avoiding high pressure operations and harmful solvents, a mild and sustainabable operaration is adopted. At this juncture, 1Pd/SBA15, 2Pd/SBA‐15 and 3Pd/SBA‐15 catalysts (where 1, 2 and 3 are wt% of Pd) were prepared by wet impregnation method and characterized by powder X‐ray Diffraction, N₂‐physorption, Scanning Electron Microscopy, Transmission Electron Microscopy, CO‐Pulse Chemisorption, H₂‐Temperature Programmed Reduction, and Inductively Coupled Plasma Optical Emission Spectroscopytechniques. Among the three catalysts, 2Pd/SBA‐15 catalyst is capable of transforming furfuryl alcohol to tetrahydrofurfuryl alcohol with nearly 100% conversion and 85% selectivity.The high surface area of SBA‐15 and high dispersion of Pd nanoparticles with large number seems to be influencing such high catalytic activity of 2Pd/SBA‐15. The 2Pd/SBA‐15 catalyst offers stable activity and selectivity during 12 h time on stream, signifying the role of support in the stabilization of Pd nano particles.

糠醇加氢制四氢糠醇的Pd / SBA-15催化剂

为了避免高压操作和有害溶剂将糠醇氢化为四氢糠醇，采用了温和且可持续的操作。此时，通过湿法浸渍法制备了1Pd / SBA15、2Pd / SBA-15和3Pd / SBA-15催化剂（其中1、2和3为Pd的wt％），并通过粉末X射线衍射N ₂表征。吸收法，扫描电子显微镜，透射电子显微镜，CO脉冲化学吸附，H ₂-温度程序化还原和电感耦合等离子体发射光谱技术。在这三种催化剂中，2Pd / SBA-15催化剂能够以近100％的转化率和85％的选择性将糠醇转化为四氢糠醇.SBA-15的高表面积和大量Pd纳米颗粒的高分散性似乎是影响2Pd / SBA-15如此高的催化活性。2Pd / SBA-15催化剂在运行12小时内可提供稳定的活性和选择性，表明载体在稳定Pd纳米颗粒中的作用。
