METHOD FOR PRODUCING A GRANULAR HUMIC DETOXICANT Russian patent published in 2021 - IPC C05F11/02 C05G5/12 

FIELD: chemistry.

SUBSTANCE: invention relates to the field of environmental safety and can be used in management of the consequences of the activity of objects of accumulated environmental hazard, defense and chemical enterprises previously producing highly toxic substances, for reclamation of man-made territories and agricultural lands, conservation and elimination of unorganised municipal and industrial waste dumping ground, detoxification of drilling sludge and sewage slurry sedimentation. The method for producing a complex granular humic organomineral detoxicant consists in the fact that the initial brown coal is dried at a temperature no higher than 60°C, ground to a particle size of no more than 100 mcm, mixed with bentonite, poured into an alkali solution. Mixing and ultrasonic treatment at a frequency in the range from 18 to 26 kHz are then performed in a flow-type reactor. The power of ultrasonic treatment of the suspension is therein greater than 10 W/cm², and the temperature of the suspension is not higher than 50°C to 60°C. The composition produced after ultrasonic treatment is granulated, followed by drying the granulate to a humidity of no more than 10%.

EFFECT: invention provides a possibility of producing a granular finished product, convenient in storage, transportation and application, with minimal power consumption.
