SOLID-FUEL GRANULATED COMPOSITION, AND METHOD FOR ITS OBTAINMENT Russian patent published in 2013 - IPC C10L5/00 C10L5/40 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to production of solid fuel, in which there described is solid-fuel granulated composition based on carbon-containing component, where as carbon-containing component, there added is disperse activated product of low-temperature pyrolysis of wastes of technical rubber products and polymer wastes (pyrocarbon with specific surface S=5000-8000 cm²/g), and wood dust is added as plant waste. At that, as the component that initiates combustion, there added are nitrogen-containing components, and binding agent is added in the form of water solution of polymer plasticising additive with total initial humidity W_initial =10÷35 wt %. Peculiar feature of granulated solid-fuel composition and method for its obtainment is increase in thermal power due to considerable acceleration of fuel combustion at reduced quantity of hazardous gaseous emission to atmosphere. Proposed ratios of components and added quantity of NH₄NO₃ as an oxidiser instead of hydrogen at combustion provides formation of NO₃, N₂ and H₂O. Excess oxygen is supplied to oxidation of fuel components.

EFFECT: obtaining fuel briquettes with high reactivity ability, increased thermal power and high strength of briquettes.
