Hydrogen production from glucose used as a model compound of biomass gasified in supercritical water

Gasification of corn and clover grass in supercritical water

“…At high temperatures the best hydrogen yield for the supercritical water gasification of sawdust and different starches was reached [6]. The same important effect of the temperature has been reported in other publications [7][8][9][10]. The pressure has no great effect on the glucose gasification efficiency and the fraction of the gas product [8].…”

Effect of Ni/Al2O3-SiO2and Ni/Al2O3-SiO2with K2O Promoter Catalysts on H2, CO and CH4Concentration by CO2Gasification ofRosa MultifloraBiomass

“…As well as, higher hydrogen (H 2 ) yield concentration is observed especially from the catalytic gasification using Ni/ Al 2 O 3 -SiO 2 catalyst than non-catalytic and catalytic Ni/ Al 2 O 3 -SiO 2 with K 2 O promoter catalyst. Thus, bio-gaseous product yields profile affirmed that the catalysts might activate Figure 9 Variations in carbon conversion degree during non-catalytic and catalytic gasification of RM at temperature of 950°C depolymerization processes to a strong decomposition (low solid yield) or a strong liquid phase cracking (low liquid yield), and hereof a higher gas formation, since this gas was formed from liquid cracking [57,58]. The recorded yields for methane are much smaller and it is formed mainly at the initial stage of the process during non-catalytic CO 2 gasification process.…”

Hydrothermal Gasification Performance of Iranian Rice Straw in Supercritical Water Media for Hydrogen-Rich Gas Production

“…In the hydrolysis reaction, biomass decomposes into intermediate compounds (e.g., glucose, fructose) (Hao 2003;Yu et al 2014). These intermediate compounds further decompose to gaseous products such as hydrogen (H2) and carbon dioxide (CO2), with small amounts of methane (CH4) and carbon monoxide (CO).…”
