FORMED COKE OBTAINING METHOD Russian patent published in 2014 - IPC C10B53/08 C10B57/08 C10L5/06 C10L5/28 

FIELD: oil and gas industry.

SUBSTANCE: method for production of formed coke of carbon-containing material includes stages of oil semi-coke heating, pressure moulding with obtainment of green mouldings and their further cocking. Oil semi-coke is heated up to 350-400°C, at that oil semi-coke with carbon-to-hydrogen atomic ratio within range of (1.3-1.7) or oil semi-coke with carbon-to-hydrogen atomic ratio more than 1.7 is used with addition of sintering additives. After the heating stage before moulding the heated oil semi-coke is hold within 10-20 s.

EFFECT: invention allows improving quality of mouldings, simplifying the method and increasing technology stability and reliability, reducing energy costs and expanding sources of raw materials.
