Abstract
Methods and systems for converting an aromatic polymer material and aromatic bottoms to needle-grade coke. An embodiment of a method includes supplying aromatic bottoms from an aromatic recovery complex; mixing the aromatic polymer material with the aromatic bottoms to obtain an aromatic polymer mixture comprising the aromatic polymer material and the aromatic bottoms; delayed coking the aromatic polymer mixture to obtain petroleum green coke and volatile components; fractionating the volatile components to obtain distillate products; and calcining the petroleum green coke to obtain needle coke.
