Hydrothermal and Supercritical Water Processing of Inorganic Substances

Subcritical Water Extraction and Hydrolysis of Cod (Gadus morhua) Frames to Produce Bioactive Protein Extracts

“…Additionally, the ionic product of water (K W ) increases with temperature, being three orders of magnitude higher than that at ambient conditions. This leads to the increase of hydronium and hydroxide ions concentrations and allows water to act as an acid or base catalyst, facilitating the hydrolysis of lignocellulosic polymers and proteins to smaller oligomers and peptides, without the use of additional catalysts [26,27].…”

One‐step synthesis of flower‐like η‐Al 2 O 3 via supercritical hydrothermal method

“…Hydroxide is one of the most effective anions in oxides synthesis in the precursor solution [45]. The solubility of the amphoteric species (such as aluminium oxide) is related to the mineraliser concentration [46]. Thus, in this research, the concentration of soluble Al‐compounds was raised by adding NaOH.…”

Direct numerical simulation of a supercritical hydrothermal flame in a turbulent jet

“…Introduction 1.1. Background of supercritical hydrothermal flames Supercritical hydrothermal combustion is a new form of supercritical water oxidation (SCWO) process that is characterized by the presence of luminous flames in supercritical water (SCW) (Augustine & Tester 2009;Brunner 2014a). The reason for the occurrence of flames in an aqueous environment is that water exhibits almost reverse solubility for various solutes as it transits from a subcritical state to a supercritical state.…”
