Synthesis, characterization and performance of bifunctional catalysts for the synthesis of menthol from citronellal

The synthesis of a series of bifunctional catalysts (1 wt% Pt/W-TUD-1 (Technische Universiteit Delft-1) and 1 wt% Pt/WO₃/TUD-1) with different tungsten loadings (5-30 wt% WO₃) is described. They were characterized using ICP-OES, INAA, N₂ physisorption, XRD and TEM. Their catalytic performance (activity and...

Pt/Al2O3 Catalyzed 1,3-Propanediol Formation from Glycerol using Tungsten Additives

Screening of four commercial catalysts (Pt/Al2O3, Pt/SiO2, Pd/Al2O3, and Pd/SiO2) and four acidic additives (hydrochloric, tungstic, phosphotungstic, and silicotungstic acids) shows that the combination of a platinum hydrogenation catalyst with tungsten containing acidic additives yields 1,3-propanediol from aqueous glycerol. The performance of...
