Selective conversion of glycerol to 1,3-propanediol using Pt-sulfated zirconia

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

“…Although its regioisomer 1,2-propanediol (12PD) can be produced at both high conversion and selectivity, [2][3][4] this proves to be more challenging for 13PD (Table 1). [5][6][7][8][9][10][11][12][13][14][15][16] Hydrogenolysis is often mistakenly identified as the process in question, however, in most instances, the process in question is an elimination of water followed by hydrogenation of the formed double bond on a metallic surface. [17,18] The catalytic role of the acidic components in the catalytic systems listed in Table 1 is the initial dehydration of glycerol.…”

A review: Conversion of bioglycerol into 1,3-propanediol via biological and chemical method

“…These liquid acids which were used as additives for solid catalyst will cause the corrosion problem in reactor and catalyst separation. Another drawback is that the reaction required high pressure (5.0-32.0 MPa) system [75,79,80,82,84,85,87,88], thus increase the production cost whereby money will be spent on high pressure equipment, as well as increase the hazardous risk such as explosions which can be due to overpressurization in the reactor and sudden arise of reaction temperature.…”

“…Conversion of 1,3-PDO through catalytic hydrogenolysis of glycerol.Bronsted acid sites in enhancing the yield of 1,3-PDO[87]. The author continued to develop the reaction by modifying the Pt-H 4 SiW 12 O 40 catalyst with alkaline metal such as Li, K, Rb and Cs.…”

Advances in selective catalytic transformation of ployols to value-added chemicals

“…Based on this catalyst system, Ding and coworkers [199] developed a bifunctional catalyst Pt/WO3/TiO2 on silica, and found that the existence of TiO2 species improved the dispersion of the Pt metal, and the WO3 species increased the acidity. Lee and coworkers [200] have developed another Pt-based catalyst by using sulfated zirconia to support the Pt metal. They found that Pt and sulfate ions were stabilized in the more active tetragonal zirconia phase.…”

“…Therefore, organic solvents (e.g. DMF) were used to produce 1,3-PG [196,197,200]. However, the use of polar aprotic organic solvents is restricted as they are not environmentally benign.…”
