Thermodynamic analysis of liquid phase in situ hydrogenation of glycerol for 1,3-propanediol synthesis

Kun OUYANG, Yu HUANG, Haoyi CHEN, Tao LI, Fahai CAO, Dingye FANG

Frontiers of Chemical Science and Engineering 2011, Volume 5, Issue 1, Pages 67-73 doi: 10.1007/s11705-010-0541-6

Abstract: Based on the combination of the glycerol aqueous-phase reforming (APR) and catalytic hydrogenation ofglycerol, a novel reaction system of liquid phase in situ hydrogenation of glycerol for the synthesisof 1,3-propanediol is proposed, in which hydrogen is produced from glycerol aqueous-phase reformingIn this new system, the glycerol is the raw material of the aqueous-phase reforming reaction; the hydrogengenerated from the APR of glycerol can be quickly transformed to the in situ hydrogenation of glycerol

Rhamnolipids Induced by Glycerol Enhance Dibenzothiophene Biodegradation in Burkholderia sp. Article

Camila A. Ortega Ramirez, Abraham Kwan, Qing X. Li

Engineering 2020, Volume 6, Issue 5, Pages 533-540 doi: 10.1016/j.eng.2020.01.006

Abstract: We utilized glycerol to stimulate Burkholderia sp.Under an optimum glycerol-to-DBT molar ratio, the DBT biodegradation rate constants increased up to 18and DBT, whereas only Rha-C12-C12 was identified in cultures without glycerol or with RL inhibitors.The studies indicated that glycerol enhances DBT biodegradation via increased RL synthesis and bacterialThe results warrant further studies of environmental biostimulation with glycerol to advance bioremediation

Frontiers of Chemical Science and Engineering 2009, Volume 3, Issue 1, Pages 52-57 doi: 10.1007/s11705-009-0087-7

Abstract: The aim of this work was to separate 1,3-PDO from a synthetic mixture using polymeric resins, Amberlite XAD-7 and XAD-16 resins. The equilibrium adsorption of 1,3-PDO onto two polymeric resins were investigated in binary and tertiary systems. Experimental results of binary component adsorption equilibrium indicated that the adsorption capacity ( ) of 1,3-PDO at 160 g/L onto XAD-7 and XAD-16 was 835.96 and 584.61 mg 1,3-PDO/g dry resin, respectively. The adsorption isotherms were closely predicted by the Langmuir-Freundlich model among the two isotherm model tested. The value of n of 1,3-PDO adsorbed on XAD-7 are much higher than those on XAD-16. This result suggested that XAD-7 resin has a higher affinity for the 1,3-PDO adsorption than XAD-16 resin. Moreover, the value of adsorption capacity of 1,3-PDO in the binary and tertiary component were compared at the same conditions. In the tertiary system, although the selectivity of 1,3-PDO from XAD-7 was approximately six times higher than XAD-16, the adsorption capacity of 1,3-PDO at 160 g/L onto XAD-16 was higher than XAD-7. Interestingly, the reusability of XAD-7 and XAD-16 resins in the three cycle times shows a slight loss of adsorption capacity. Furthermore, the investigation about desorption by an ethanol/water mixture at 50% ( / ) indicated that the desorption yield of 1,3-PDO from XAD-7 was lower than XAD-16 resin for both the binary and tertiary component. This was due to the more favorable adsorption characteristics of XAD-7 resin than XAD-16 resin.
