The property of its supercritical water can be changed remarkably by controlling its temperature and density. Application of its characteristics may make possible the decomposition, liquefaction and/or alteration of coal and other heavy fossil fuels, and the removal of sulfur, nitrogen, heavy metals and so on. In this report, decomposition treatments for liquefaction of coal in supercritical water are reviewed. Result of other fossil fuels such as oil sands are also presented.
