Supercritical Water Is Not Hydrogen Bonded [PDF]

open access: yesAngewandte Chemie - International Edition, 2020
AbstractThinking about water is inextricably linked to hydrogen bonds, which are highly directional in character and determine the unique structure of water, in particular its tetrahedral H‐bond network. Here, we assess if this common connotation also holds for supercritical water.

Supercritical Water Gasification of Biomass: A Literature and Technology Overview

open access: yesEnergies, 2015
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.
