Pd/SBA‐15 Catalysts for Hydrogenation of Furfuryl Alcohol to Tetrahydrofurfuryl Alcohol

Abstract

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.

Hydrodeoxygenation of m-cresol over Pd/Al-SBA-15 catalysts: Effect of Al content on the deoxygenation reaction pathways

“…supports. The H2-TPR profiles of the Pd/SBA as well as the materials containing 5 and 20 % of Al revealed the presence of two peaks at low temperatures which corresponds to the reduction of palladium oxide particles [49,50]. It is well known that PdO reduces easily at low temperatures (below 200 °C) [11,16,20,[49][50][51].…”

It is well known that PdO reduces easily at low temperatures (below 200 °C) [11,16,20,[49][50][51]. The H2 consumption at lower temperature (70-73 °C) is associated with the reduction of PdO outside of the pores, and the one at higher temperature (88-92 °C) is due to the reduction of PdO inside the pores.…”

Selective Hydrogenolysis and Hydrogenation of Furfuryl Alcohol in the Aqueous Phase Using Ru–Mn-Based Catalysts

“…Chada et al obtained 85 C % selectivity of THFA from furfuryl alcohol over the Pd/SBA-15 catalyst. 17 Wang et al reported the Pt/CeO 2 catalyst with a special crystal plane of (100) for efficient hydrogenolysis of furfuryl alcohol into 1,2-PeD. 18 Amada et al reported the direct transformation of furfural to 1,2-PeD (73 C%) using a Pt/HT nanoparticle catalyst.…”

Doping Pd/SiO2 with Na+: changing the reductive etherification of CO to furan ring hydrogenation of furfural in ethanol

“…7 d Other studies on FAL hydrogenation over Pd/SiO 2 also showed that Pd NPs on SiO 2 were very selective toward the hydrogenation of furan ring. 8 On the other hand, some reports have found that Pd/SiO 2 was an excellent catalyst for the reductive etherification of C O bond in aldehydes like cyclohexanone and etc. 9 We speculate that the introduction of Na during the catalyst preparation may have a profound role in this process.…”
