METHOD FOR PRODUCTION OF POROUS GRANULAR AMMONIUM NITRATE Russian patent published in 2018 - IPC C01C1/18 C06B31/28 

FIELD: chemistry.

SUBSTANCE: method involves the introduction of a stabilizing additive into the ammonium nitrate solution with simultaneous neutralization with ammonia. Further, the solution is evaporated to form a melt and a dispersant and a pore-forming additive are added to the resulting melt. Granulation of the melt is carried out by dispersing in the cooling air flow and conditioning of the resulting granules. Nitrogen gas is used as the pore-forming additive.

EFFECT: increased absorbing and retaining capacity of ammonium nitrate granules in relation to diesel fuel, increased static strength, increased thermal stability of granules.
