Abstract
The invention disclosed in this application is a process for the production of a premium grade needle coke which is historically feedstock dependent. The selected feedstock for this process is a hydrotreated SRC material (solvent refined coal) which produces a premium grade needle coke having a low ash, low sulfur and low solids content. The hydrotreating of the SRC material, before conversion to the premium grade needle coke, changes the molecular structure of the product by putting hydrogen therein and results in a different arrangement of the aromatic molecules in the resultant premium grade needle coke.
