METHOD OF PRODUCING FUEL BRIQUETTE (VERSIONS) Russian patent published in 2010 - IPC C10L5/02 C10L5/14 C10L5/44 

FIELD: process engineering.

SUBSTANCE: invention relates to production of fuel briquettes from carbon-containing fine-fraction materials. Proposed method comprises preliminary mixing of melasses and lime-containing component to get modified binder to be mixed with fine-fraction carbon-containing mineral material and forming briquettes with the following ratio of components, % by weight: melasses 1.8-7.0, lime-containing component (in terms of Ca(OH)₂) 0.8-3.2, fine-fraction carbon-containing mineral material making the rest. Ratio between melasses and carbon-containing component (in terms of Ca(OH)₂) makes 1:(0.25-0.75), respectively. In compliance with the other version, proposed method comprises preliminary mixing of melasses and lime-containing component to get modified binder to be mixed with fine-fraction carbon-containing mineral material, fine-fraction vegetable materisl and forming briquettes with the following ratio of components, % by weight: melasses 3.0-9.0, lime-containing component (in terms of Ca(OH)₂) 1.2-4.5, fine-fraction carbon-containing vegetable material 5.0-20.0, and fine-fraction carbon-containing mineral material making the rest. Ratio between melasses and carbon-containing component (in terms of Ca(OH)₂) makes 1:(0.25-0.75), respectively.

EFFECT: improved ecological properties, simplified production process.
