Abstract
The invention provides: a fuel composition comprising 100 parts by weight of a coal-liquid fuel mixture and 0.02 to 1.0 part by weight of at least one additive selected from the group consisting of dibenzylidene sorbitol, ditoluylidene sorbitol, tribenzylidene sorbitol, tritoluylidene sorbitol and hydrogenated castor oil; and a fuel composition comprising 100 parts by weight of a coal-liquid fuel mixture, 0.02 to 1.0 part by weight of at least one additive selected from the group consisting of dibenzylidene sorbitol, ditoluylidene sorbitol, tribenzylidene sorbitol, tritoluylidene sorbitol and hydrogenated castor oil, and 1 to 10 parts by weight of water. The composition shows high stability over a prolonged period of time, preventing the separation into layers of the components.
