It relates to a mixed coal oil containing an adduct. The mixed coal oil of the present invention is particularly effective in mixed coal oil obtained from highly weathered coal (hereinafter referred to as weathered coal), but is not limited thereto. Typical examples of weathered coal are Blairsol coal, Western Coal, Saxon Bell coal and the like. Pulverized coal is coal crushed to pass 70% or more of 200 mesh sieve, and mixed coal oil is dispersed in fuel oil such as heavy oil, kerosene, light oil, waste oil such as machine oil and lubricating oil, tar oil, etc. Obtained. The mixing ratio of pulverized coal and fuel oil is 30: 70-60:
40 (weight ratio) is generally used, and a surfactant as a dispersion stabilizer is added thereto in an amount of about 0.05 to 0.5% by weight.

Etc. are illustrated. As amines, primary and secondary having 3 or less carbon atoms
Examples include secondary, tertiary amine salts, quaternary ammonium salts, alkanolamines such as monoethanolamine, diethanolamine and triethanolamine, nitrogen-containing heterocyclic compounds such as morpholine and pyridine, and aromatic amines such as aniline. However, it may have an alkyl group larger than this. However, higher amines are expensive, have skin disorders, and in addition require higher amounts to regulate pH. Therefore, in the present invention, it is appropriate to use a lower amine.

When the alkylene oxide addition type nonionic surfactant is used as a dispersant for mixed coal oil, it may be used for pH adjustment of the present invention without neutralizing the alkali catalyst used in the reaction. When an inorganic alkali is used, its fine powder may be directly added to the mixed coal oil, or may be dissolved or dispersed in water or the dispersant used before use. In general, the water content should be as low as possible to prevent ash deposits, preferably not more than 5% by weight of the total blended coal oil. Particularly preferably, it is suitable to suppress the water content to 2% by weight.

For the measurement of pH, 1% of mixed coal oil is added to distilled water or deionized water, vigorously stirred (for example, shaken in a dispersion funnel for at least 1 minute), and after standing, the oil layer is separated and the pH of the water tank is measured. The dispersion stabilizer used in the mixed coal oil of the present invention may be any of a nonionic surfactant, an anionic surfactant and a cationic surfactant, but it is used for a dispersion stabilizer such as a nonionic surfactant which is relatively easy to cause ash deposition. Is especially effective.
