Abstract

PURPOSE: To prepare an emulsion fuel composed of water and coal particles dispersed uniformly and stably in an oil, by mixing and dispersing an alkali-treated coal (fumic acid alkali metal salt) and an alkaline aqueous solution in fuel oil.
CONSTITUTION: Coal is decomposed and extracted with (pref. ≤20wt% of) at least one salt selected from hydroxide, carbonate and bicarbonate of an alkali metal or an alkaline earth metal at ≤250°C to obtain a humic acid alkali salt soluble in an alkaline aqueous solution. The objective emulsion fuel is prepared by mixing and dispersing (pref. ≤25% of) the salt and ≥20% of the alkaline aqueous solution in a fuel oil. The coal used as the raw material is pref. the one containing ≥25% of oxygen and having the particle size of about 60mesh.
