SOLID FUEL COMPOSITION (VERSIONS) Russian patent published in 2013 - IPC C06D5/06 C06B31/30 

FIELD: chemistry.

SUBSTANCE: invention relates to solid fuel compositions based on ammonium nitrate and can be used to clean oil wells from asphalt-resin-paraffin deposits, hydraulic fracturing during oil extraction and as a source of energy of solid-fuel rocket engines. The solid fuel composition contains, wt %: ammonium nitrate 69-77, powdered butadiene-nitrile rubber with particle size of 0.4-2.0 mm 10-12, ASD-1 aluminium powder 8-15, potassium dichromate 1-8 and a process additive (0.5-1.0) in excess of 100%. Another version of the solid fuel composition contains, wt %: ammonium nitrate 69-77, powdered butadiene-nitrile rubber with particle size of 0.4-2.0 mm 10-12, ASD-1 aluminium powder 4.0-7.5, ultrafine aluminium with particle size of 0.1 mcm 4.0-7.5, potassium dichromate1-8 and a process additive (0.5-1.0) in excess of 100%.

EFFECT: high combustion rate of the solid fuel composition at high pressure and low content of solid combustion products.
