Heavy cycle oil and slurry oil
Bottoms of the FCC main fractionator (heavy cycle oil with the slurry or clarified oil), polyaromatic, with catalyst fines until clarified; to fuel oil or carbon black feed (processes/fcc-1). No composition recorded yet: one goes in only with its source (docs/registry.md, Fuel mixtures).

ISO 14044 requires a critical review (by a panel of interested parties, ISO/TS 14071) of a comparative assertion intended to be disclosed to the public. These routes are listed side by side for screening; a statement that one is better than another needs that review. None of these routes has had such a review.
