摘要： A method of recovering humic acids from a material such as oxidised coal is provided. This method includes the steps of mixing the material with aqueous alkali, particularly aqueous sodium hydroxide, heating the mixture to a temperature above 100.degree. C. and below 180.degree. C. under sufficient pressure to prevent evaporation of the water, and maintaining the elevated temperature for a time, generally less than 2 hours, sufficient to extract a substantial amount of the available humic acids from the material.

摘要： This invention relates to the production of a solid oxidized coal containing humic acids. Coal with a mean particle size of less than 3 mm is slurried with water and then oxidized with oxygen or mixtures of oxygen and air at temperatures ranging from 100.degree. to 300.degree. C., at partial oxygen pressures ranging from 0,1 to 10 MPa and reaction periods ranging from 5 to 600 minutes. In the absence of catalysts, e.g. alkaline bases, the main product of oxidation is humic acids. These humic acids are not dissolved because the pH of this slurry is in the range 4 to 9. Small amount of fulvic acids are formed and these are soluble in the water of the slurry.The coal-derived humic acids may for example find application as soil conditioners, organic fertilisers, briquette and pellet binders, drilling fluid dispersants and viscosity control agents, while the coal-derived fulvic acids may be utilized for the production of fuel extenders, plasticizers and petrochemicals.
