摘要：
A method for preparing a high-solids concentration low rank coal slurry by dehydrating the coal, treating the dehydrated coal with a rehydrating inhibitor such as a (C.sub.3 -C.sub.12) straight chain hydrocarbon, and adding a surfactant to the treated coal, whereby the concentration of the solids is increased from about 5 to about 20 wt. %.
