ABSTRACT:
A non air-blown low sulfur heavy aromatic mineral oil which does not produce acceptable isotropic coke when subjected to delayed coking is combined with an inorganic additive which promotes pyrolysis and which vaporizes during calcining and the combination is subjected to delayed coking to produce isotropic coke having a low CTE ratio. The isotropic coke is further processed (including calcination) to produce graphite logs used in nuclear reactors.
