ABSTRACT:
The invention relates to the upgrading of coal for coking purposes and improved cokes resulting from such upgrading. Pitch obtained as a by-product of pressure-gasification (Lurgi-process) is used as an additive either alone or blended with SRC. The additive is employed in amounts of 1% and 50% by mass, preferably 5 to 15% of the total blend. The additive preferably has an R-and-B softening temperature above 80.degree. C. The additive can be subjected to various treatments, e.g. heating in presence of hydrogen, to improve its characteristics.
