Production of Propanediols through In Situ Glycerol Hydrogenolysis via Aqueous Phase Reforming: A Review
نویسندگان
چکیده
Production of 1,2-propanediol and 1,3-propanediol are identified as methods to reduce glycerol oversupply. Hence, hydrogenolysis is a thermochemical conversion substitute; however, it requires an expensive, high-pressure pure hydrogen supply. Studies have been performed on other potential processes whereby aqueous phase reforming has excellent substitute for the process due its low temperature requirement high H2 yields, factors which permit in-situ no external this manuscript emphasizes delving into possibilities concept produce without “breaking bank” with expenses. Various heterogenous catalysts (APR) were identified, combination noble metal, support, dopant good amount Brønsted acid sites key ensure yield 1,3-propanediol. However, 1,2-propanediol, Cu-based catalyst decent basic support observed be selectivity product. The findings shown that possible yields both via reforming, specifically some achieve better compared direct 1,2-propanediol. This not case 1,3-propanediol, further studies need conducted evaluate feasibility.

Optimised Hydrogen Production by Aqueous Phase Reforming of Glycerol on Pt/Al2O3
Aqueous phase reforming of glycerol was studied over a series of γ-Al2O3 supported metal nanoparticle catalysts for hydrogen production in a batch reactor. Of the metals studied, Pt/Al2O3 was found to be the most active catalyst under the conditions tested. A further systematic study on the impact of reaction parameters, including stirring speed, pressure, temperature, and substrate/metal molar...

Activity improvement of Ru-based catalysts is needed for efficient production of valuable chemicals from glycerol hydrogenolysis. In this work, a series of Re promoted Ru catalysts encapuslated in porous silica nanoparticles (denoted as Re-Ru@SiO₂) were prepared by coating silica onto the surface of chemically reduced Ru-polyvinylpyrrolidone colloids, and were used to catalyze the conversion of...

High temperature/pressure in situ Attenuated Total Reflection Infrared (ATR-IR) spectroscopy was used to investigate the phase transformation of support γ-Al2O3 into boehmite (AlO(OH)) under the hydrothermal conditions of aqueous phase reforming (APR). Activation energy barriers of boehmite formation in hot compressed water at temperatures between 150 and 180 °C were calculated to be 15.9 ± 4.8...

Recently, a series of three-component compounds with the combination of Mn+1AXn known as Max phases have been considered as a new material. One of the most important features of Max phases, is the self-healing property of them. The main reason for considering Max Phases is a unique collection of unusual properties including their metallic, ceramic, physical, and mechanical properties. One of th...
