LIQUID COAL FUEL Russian patent published in 2015 - IPC C10L1/32 

FIELD: chemistry.

SUBSTANCE: invention describes a liquid coal fuel which consists of a finely dispersed mixture of a solid part in the form of semicoke/coke microparticles and a liquid part in the form of a tar fraction, obtained after thermal processing of raw coal, where the finely dispersed mixture is a double suspension-emulsion system, wherein the solid part used is a combination of microparticles of raw coal and the product of thermal processing thereof in the form of semicoke/coke microparticles, and the liquid part used is liquid products of thermal processing of the same raw coal, wherein the tar fraction is used to encapsulate groups of solid microparticles of raw coal and semicoke/coke in emulsion microdroplets, and the tar water is used as the dispersion medium.

EFFECT: obtaining liquid coal fuel with low viscosity and abrasiveness, which provides prolonged use of the burner, enables to obtain a flame with good atomisation and avoids the use of second lifting pumps and additional fuel heaters in the fuel circuit.
