1: Supercritical water is used in upgrading low rank coals such as lignite, wet oxidation of wastes and for treating sewage sludge among other applications. The report here from 1992 presents a speculation for the molecular structure of SC water that explains its low polarity and solvency for hydrophobic materials and perhaps its peculiar acid-base properties as well. I call it Kekulé's vision which is a conceit I admit. Certain spectroscopic analysis since 1992 has suggested a model where SC water does consist of trimer and tetramer clusters of water but these more tree-like than ring-like . Nevertheless I like the ring model. Perhaps there are conditions where rings are formed in greater abundance. We shall see.
