Abstract

Способ производства водорастворимых гуминовых кислот, содержащий сушку бурого угля с содержанием гуминовых кислот не менее 50%, измельчение бурого угля, обработку измельченного угля щелочным реагентом, отличающийся тем, что бурый уголь перед измельчением высушивают до остаточной влажности не более 20%, после измельчения разделяют на фракции: более 10 мм, 4÷10 мм, 2÷4 мм, 0,5÷2,0 мм и менее 0,5 мм, фракции более 10 мм и 4÷10 мм возвращают на домол, фракции 2÷4 мм и менее 0,5 мм в твердой фазе обрабатывают сухим щелочным реагентом при интенсивном перемешивании с поддержанием температуры в диапазоне 40÷80°С, фракцию 0,5÷2,0 мм при интенсивном перемешивании диспергируют в умягченной воде и обрабатывают водным раствором щелочного реагента с поддержанием рН реакционной смеси в диапазоне 10,0÷10,5 и температуры в диапазоне 40÷80°С, очищают полученный в результате реакции раствор от нерастворимых в воде веществ центрифугированием, концентрируют раствор упариванием под разряжением при остаточном давлении 5000÷6000 Па и температуре 50÷60°С, затем сушат в кипящем слое при температуре 130÷140°С. A method for the production of water-soluble humic acids, comprising drying brown coal with a humic acid content of at least 50%, grinding brown coal, treating the crushed coal with an alkaline reagent, characterized in that the brown coal is dried to a residual moisture content of not more than 20% before grinding, after grinding it is divided into fractions: more than 10 mm, 4 ÷ 10 mm, 2 ÷ 4 mm, 0.5 ÷ 2.0 mm and less than 0.5 mm, fractions more than 10 mm and 4 ÷ 10 mm are returned to the mantle, fractions 2 ÷ 4 mm and less than 0.5 mm in the solid phase is treated with a dry alkaline reagent with vigorous stirring and maintaining the temperature in the range of 40 ÷ 80 ° C, the fraction of 0.5 ÷ 2.0 mm with vigorous stirring is dispersed in softened water and treated with an aqueous solution of an alkaline reagent while maintaining the pH of the reaction mixture in the range of 10.0 ÷ 10.5 and temperature in the range of 40 ÷ 80 ° C, the solution obtained from the reaction is purified from water-insoluble substances by centrifugation, the solution is concentrated by evaporation under vacuum at a residual pressure of 5000 ÷ 6000 Pa and a temperature of 50 ÷ 60 ° C, then it is dried in a fluidized bed at a temperature of 130 ÷ 140 ° C.
