METHOD OF SPEEDED DOWN CARBONIZATION Russian patent published in 2008 - IPC C10B55/00 

FIELD: .oil industry

SUBSTANCE: method comprises preliminary heating of initial raw material, mixing it with the carbonization gas oil, supplying the mixture to the intermediate tank, heating the raw material up to the temperature of carbonization, and carbonizing it in the carbonization chamber to produce carbon and carbonization distiller. The distiller is supplied to the bottom section of the rectification tower in which it is separated into gas, gasoline, and light and cubic carbonization gas oils. The other heated hydrocarbon raw material is additionally supplied to the bottom section of the rectification tower. The concentration of sulfur in the material is higher than that in the initial raw material . The cubic gas from the rectification tower is carbonized by a known method to produce coke and distiller which is supplied to the bottom section of the rectification tower. The initial raw material can be mixed with the light or heavy carbonization gas oil.

EFFECT: simplified method.
