METHOD OF PRODUCING MODIFIED COAL AND MODIFIED COAL Russian patent published in 2018 - IPC C10L9/06 

FIELD: oil, gas and coke-chemical industries.

SUBSTANCE: invention describes a method for producing a modified coal from low-grade coal as a raw material, comprising a step of dehydrating low-grade coal in oil; a step of adding water to the dehydrated coal; a step of agglomerating the coal-containing coal and a step of gradually oxidising the agglomerated coal, wherein at the step of adding water, the added amount of water is controlled such that the coal containing the added has a water content of 5 wt% or more and 20 wt% or less, and at the oxidation step, the agglomerated coal is held in air at a temperature of 70°C or higher and 100°C or lower, where the rate of oxygen consumption by the oxidised coal after the oxidation step is 1 mg/g per day or less. Modified coal obtained by this method is also disclosed.

EFFECT: technical result consists in obtaining modified coal in which the dust formation and any spontaneous combustion is minimised.
