In order to avoid the water evaporation, the reaction was carried out in a fixed-bed continuous flow reactor. Glycerol was converted into 1,3-PDO over Pt/WO 3 /ZrO 2 at 403 K under 4 MPa H 2 pressure. The selectivity of 1,3-PDO was 45.6% and glycerol conversion was 70.2% [83]. Gong et al. converted glycerol to 1,3-PDO over SiO 2-supported Pt/WO

Production of 1,3-propanediol (1,3-PDO) from glycerol is a promising route toward glycerol biorefinery. However, the yield of 1,3-PDO is limited due to the requirement of NADH regeneration via

A series of Ni-based catalysts, including Ru/SiO 2, Ni/SiO 2 and Ru–Ni/SiO 2, were prepared and employed in the hydrogenation of 3-hydroxypropanal (3-HPA) to 1,3-propanediol (1,3-PDO).The catalysts were systematically characterized by means of XRD, TEM, HRTEM, SEAD, XPS, H 2-TPD, H 2-TPR and N 2-physisorption.It was indicated that the
