Glyceraldehyde production from glycerol over Pt/CeO2-ZrO2-Fe2O3/SBA-16 catalysts around room temperature in open air system

Production of Hydroxypyruvic Acid by Glycerol Oxidation over Pt/CeO2-ZrO2-Bi2O3-PbO/SBA-16 Catalysts

“…The surface area decreased with an increase in Pb content- In our previous studies, we demonstrated the high yields of DHA and GLA over Pt/CeO 2 -ZrO 2 -MO x /SBA-16 (MO x = Bi 2 O 3 and Fe 2 O 3 , SBA-16: Santa Barbara Amorphous No. 16) using CeO 2 -ZrO 2 -MO x promoters with high oxygen release and storage abilities under moderate reaction conditions of 30 • C and atmospheric pressure [18][19][20]. The oxygen supply from the promoter facilitated the oxidation ability of Pt, and the moderate conditions suppressed further oxidation of the products, resulting in a high DHA yield of 76% for Pt/CeO 2 -ZrO 2 -Bi 2 O 3 /SBA-16 [18] and a high GLA yield of 22% for Pt/CeO 2 -ZrO 2 -Fe 2 O 3 /SBA-16 [20].…”

“…Due to these reasons, the high HA and DHA yields for Pt/CZBi(0.20)Bi(0.05)/SBA might be obtained. In general, catalytic activity is dependent on the surface area; however, Pt/CZBi(0.20)Pb(0.05)/SBA exhibited the high glycerol conversion compared to the Pt/SBA [20] case, regardless of the low surface area (Pt/CZBi(0.20)Pb(0.05)/SBA: 236 m 2 •g −1 , Pt/SBA: 476 m 2 •g −1 [20]). This result supports that the oxidation ability of Pt was enhanced by the CZBi(0.20)Bi(0.05) promoter.…”

Dihydroxyacetone production by glycerol oxidation under moderate condition using Pt loaded on La1−xBixOF solids

“…Table 1 shows the glycerol conversion and product yields for Pt/La 1− x Bi x OF/SBA and Pt/SBA. 19 The glycerol conversion of Pt/LaOF/SBA was higher than that of Pt/SBA, whereas the yields (DHA, HA, GLA, GA, TA, MA, GLOA, and OA) were nearly the same. This result suggests that glycerol adsorption was facilitated by the high ionicity of La 3+ in LaOF, as LaOF itself was insufficient to accelerate glycerol oxidation.…”

“…The Brunauer–Emmett–Teller (BET) specific surface areas of Pt/La 1− x Bi x OF/SBA (Table S1, ESI†) were almost the same (approximately 400 m 2 g −1 ) and lower than that of SBA-16 (560 m 2 g −1 ). 19 Nitrogen adsorption–desorption isotherm analysis of Pt/La 0.95 Bi 0.05 OF/SBA demonstrated that the mesoporous structure of SBA-16 was preserved after La 0.95 Bi 0.05 OF and Pt loading onto SBA-16 (Fig. S3, ESI†).…”

Critical Review on Production of Glycerol Carbonate from Byproduct Glycerol through Transesterification

“…Glycerol can be converted into several value-added derivatives such as mono-/di-/triglycerol ester, 1,2 propanediol, mesoxalic acid, glycerol 1,3-bromo- and iodohydrins, dihydroxyacetone, glyceric acid, oxalic acid, tartronic acid, syngas, hydrogen, glycerol carbonate, polyglycerol mono-/di-/tri-GTBE, etc. as summarized in Table . − …”
