WAY OF ULMIFICATION OF VEGETAL RESOURCES Russian patent published in 2012 - IPC C05F11/02 

FIELD: wood chemical processing, peat industry and agriculture.

SUBSTANCE: invention refers to the field of wood chemical processing, peat industry and agriculture and can be used for production of surface-active agents, plant growth stimulants and duff fertilizers based on lignocarbohydrate vegetal resources. The essence of the suggested ulmification method for vegetal resources lies in the fact that lignocarbohydrate material undergoes mechanochemical processing with the help of ammonium persulphate with the amount of 0.2 g/g of the raw material with the presence of ammonia water with the amount of 0.1 g of NH₃/g of the raw material within 10 minutes in the chemical reactor of the planetary mill AGO-3 with the filling degree of 25 %. Further on the stock is carried over to the hydrodynamical cavitating device and endures a cavitating influence with the rotary speed of 3,000 rpm at the temperature of 60°C and the water duty 133-1333 within 20 min. Then the liquid part is separated in the centrifuge process and extraction of humic acids from the liquid part is performed with its acidifying by a mineral acid up to pH 2.

EFFECT: intensification of the alkaline hydrolysis process of the organic matter containing in the vegetal resources.
