Abstract

The selective aqueous phase hydrogenolysis of furfuryl alcohol (FFalc) to 1,5-pentanediol (1,5-PeD) using supported bimetallic ruthenium-tin (Ru-Sn) catalysts on various metal oxide supports (e.g., TiO2, ZnO, ZrO2, Nb2O5, g-Al2O3) and its combination were investigated systematically. The catalysts were prepared via coprecipitation-hydrothermal at 150 oC for 24 h, followed by reduction with H2 at 400 oC for 2 h. Supported Ru-Sn on TiO2(A), g-Al2O3, and ZrO2 catalysts exhibited higher yield of 1,5-PeD (55-69%) than that other catalysts at 180 oC, H2 10-30 bar for 3-5 h. However, those supported catalysts showed poor recyclability after the first reaction run, and therefore further examination on g-Al2O3 supported Ru-Sn was performed. The Ru-Sn catalyst supported on g-Al2O3-metal oxide composites (metal oxides: ZrO2, TiO2(A), TiO2(R), ZnO, Nb2O5, and C) afforded higher FFalc conversion and yield of 1,5-PeD than that of unmodified g-Al2O3 at 180 oC, H2 30 bar for 3 h. Among them, the Ru-Sn/g-Al2O3-TiO2(A) (33%) catalyst could afford the highest yield of 1,5-PeD (80%) at 99% conversion FFalc at 180 oC, H2 10 bar for 5 h. Around 95% of this catalyst can be recycled after the second reaction run and the activity can be restored to initial after reactivation with H2 at 400 oC for 2 h with a 69% yield of 1,5-PeD at 97% FFalc conversion.

Abstract

Biomass-derived platform C5-furanic compounds such as furfural (FFald) and furfuryl alcohol (FFalc) can be converted into 1,5-pentanediol (1,5-PeD), an important intermediate for textiles and plastics, via catalytic hydrogenolysis reaction. However, catalyst selectivity for the hydrogenolysis reaction of FFalc to 1,5-PeD remains a challenge. In this study, modification of ZrO2 with metal oxides such as TiO2(R), TiO2(A), g-Al2O3, and active carbon (C) as the supports of bimetallic ruthenium-tin (Ru-Sn) catalysts for the selective hydrogenolysis of furfuryl alcohol (FFalc) to 1,5-pentanediol (1,5-PeD) has been investigated systematically. The modified-ZrO2 supports were prepared by physical mixing using oxalic acid as a binder at room temperature, followed by calcination under N2 at 300°C (ramping 2.5°C min−1) for 2 h. The supported Ru-Sn catalysts were synthesised by using the coprecipitation-hydrothermal method at 150°C for 24 h and reduced with H2 at 400°C (ramping 3.3°C min−1) for 2 h. The synthesised catalysts were characterised by means of XRD, H2-TPR, and NH3-TPD. The pristine structures of ZrO2, TiO2, and g-Al2O3 were maintained during the preparation of catalysts. Ru-Sn/ZrO2-TiO2(A) catalyst (Ru = 4 wt%, Sn = 1.30 wt%, ZrO2 = 67 wt%, and TiO2 (A) = 33 wt%) with calcination temperature of 300°C gave the highest yield of 1,5-PeD (72%) at 140°C, H2 10 bar for 3 h.
