Key words: supercritical water, coal, coal agglomeration
Agglomeration of coal with various degree of metamorphism at water treatment under
supercritical condition at temperature range from 380 to 800 °C has been investigated. The
formation of solid agglomerates from powders of noncaking coal has been revealed. Solidity
of agglomerates obtained at adding formic acid is measurable with the solidity of lump coal.
