Abstract
The invention described herein relates to a novel process to create carbon black feed stocks derived from coal by utilizing direct coal liquefaction resulting in an economic process for producing carbon black feedstock. Moreover, relative to the current state of the art (use of FCC slurry oil), the invention process will be significantly more profitable when oil prices increase.
