Hydrogenation of 3-Hydroxypropanal to 1,3-Propanediol over Cu-V/Ni/SiO2 Catalyst

Abstract

A Copper and Vanadium modified Ni-based catalyst (5Cu-20V/30Ni/SiO2) was synthesized and employed in the hydrogenation of 3-hydroxypropanal (3-HPA) to 1,3-propandiol (1,3-PDO). The catalysts were systematically characterized by means of XRD, TEM, HRTEM, SAED, H2-TPD, N2-physisorption, H2-TPR and XPS. It was indicated that the addition of Cu and V not only promoted the reduction of the Ni2+ species and the generation of active hydrogen species, but also increase the dispersion of Ni species and the interaction between the Ni particles and SiO2. The catalytic performance evaluation showed that the (5Cu-20V/30Ni/SiO2) could provide the largest yield of 1,3-PDO (above 76.8%) and highest TOF(4.32 × 103 S-1). Structure-activity relationship is clarified according to characterization results. An optimized reaction conditions over the 5Cu-20V/30Ni/SiO2 catalyst has been obtained as the reaction temperature is 80 ℃, H2 pressure is 2.0 MPa (H2) and LHSV is 0.4 h-1. The application of non-noble metal, the relatively low pressure of H2 and the relatively high yield of 1,3-PDO make 5Cu-20V/30Ni/SiO2 an efficient and economic catalyst that may have potential applications in industry.
