GAS-GENERATING FUEL FOR DOWNHOLE APPARATUS Russian patent published in 2010 - IPC C06B29/22 C06D5/06 

FIELD: chemistry.

SUBSTANCE: invention relates to gas-generating solid fuels. The gas-generating fuel for downhole apparatus contains ammonium perchlorate as an oxidising agent, synthetic hydrocarbon rubber plasticised with hydrocarbon oil as fuel, lecithin, epoxy resin, ortho-tert-butyl-para-cresol or tertiary butylphenol as a processing additive, paradinitrosobenzene or quinol ether as a curing agent, ammonium chloride as a gas-generating additive. The synthetic hydrocarbon rubber used can be isoprene, butadiene, ethylenepropylene, isoprenedivinyl or butyl rubber and the hydrocarbon oil can be transformer, aviation or industrial oil.

EFFECT: invention ensures high energy output of the fuel, increases content of hydrogen chloride in fuel combustion products, high specific volume of the generated gases and absence of a condensed phase in the combustion products.
