ABSTRACT:
The invention describes a process and apparatus producing a dense coke fraction from a first particulate coke fraction having a first average density and a first average particle size distribution, stratifying the coke fraction in a density separator into at least two fractions, the at least two fractions comprising a light coke fraction and the dense coke fraction. The dense fraction having an average density greater than the first average density and a particle size distribution substantially equivalent to the first average particle size distribution. The apparatus includes an inclined oscillating table comprising a gas-pervious deck, and a gas mover.
