Method for comprehensively processing brown coal and leonardite into humic fertilizers and preparations and into fuel briquettes, and mechanochemical reactor for processing highly-viscous media

A method for continuously converting raw material comprising brown coals, including leonardite, into humic fertilizers and fuel briquettes,

• wherein the humic fertilizers are selected from:
• ballast organic fertilizers in the form of suspended gels, ballast organomineral fertilizers in the form of suspended gels, ballastless solutions of humic acid, ballastless solutions of fulvic acid, ballastless dry humic acid salts and ballastless dry fulvic acid salts;
• wherein said method comprises
• first grinding the raw material to less than 3 mm,
• subjecting the ground raw material to two consecutive first and second liquid-phase mechanoactivation and/or mechanochemical activation treatments in a first mechanochemical reactor and a second mechanochemical reactor, respectively,
• wherein the first liquid-phase mechanoactivation and/or mechanochemical activation treatment in the first mechanochemical reactor comprises either liquid-phase oxidation with hydrogen peroxide or treatment with water and the second liquid-phase mechanoactivation and/or mechanochemical activation treatment in the second mechanochemical reactor comprises aqueous alkaline treatment;
• and
• wherein the first and second mechanoactivation and/or mechanochemical activation treatments are performed with dispersion of a medium being converted inside the first and second mechanochemical reactors by chafing and dynamic shift of layers of the medium by exposing the medium to hydraulic impulse with frequencies ranging in the sonic and infrasonic frequencies, by metered introduction into the medium of 10 to 40 MJ per cubic meter of mechanical energy, with automatic limitation of the energy in a sub-cavitation area for preventing the first and second mechanochemical reactors from falling into cavitation modes;
• the method further comprising mechanical phase division of converted suspension compositions into solid and liquid phases in a centrifugal force field, optionally acidizing the liquid phase with a withdrawal of humic acids from the liquid phase to a heavy phase, and recycling of residual water.
