The storage stability of coal liquids is of great importance if coal liquefaction products are to replace petroleum products. It has been reported that gum formation occurs in coal-derived liquids during storage to a level at which it becomes a handling problem. The aging of coal hydropyrolysis liquids has been studied. Coal liquid products were placed in preweighed sample vials and stored
