“…Hydrogen formation as Fig. 7.18 Hydroxymethylfurfural with its two functional groups: an aldehyde and an alcohol product is thermodynamically possible at this low temperature, but the concentration has to be very low at around 1% (Feng et al 2004;Kruse 2008). A hydrogenation catalyst is necessary.…”

“…Feng et al [130] were the first researchers who performed a thermodynamic analysis of a supercritical water biomass gasification plant. They have analyzed the phase behavior and phase equilibria in the reactor and separators; in addition, they designed an optimized heat exchange network and performed a system exergy analysis.…”

Abstract:The supercritical water gasification process is an alternative to both conventional gasification as well as anaerobic digestion as it does not require drying and the process takes place at much shorter residence times; a few minutes at most. The drastic changes in the thermo-physical properties of water from the liquid state to the supercritical state make it a promising technology for the efficient conversion of wet biomass into a product gas that after upgrading can be used as substitute natural gas. The earliest research goes back as far as the 1970s and since then, supercritical water has been the subject of many research works in the field of thermochemical conversion of wet biomass. This article reviews the state of the art of the supercritical water gasification technology starting from the thermophysical properties of water and the chemistry of reactions to the process challenges of such a biomass based supercritical water gasification process plant.

“…In contrast the HTL yield for wood chips is about 35 wt% of dry feedstock. However, the fatty acid carbon range from seaweed of 14 and 24 is closer to the conventional diesel carbon range than the heavier wood based bio-oil (Feng et al, 2004). HTL of brown seaweed is estimated to produce bio-oil yields of 23 kg/100 kg dry seaweed for light crude and 10 kg/100 kg dry seaweed for heavy crude (Reith et al, 2005).…”
