The impact of the four fractions of residue on products and the plant

I would appreciate it if experts could analyze the impact of the four components in coking feedstock residue oil on the products and the plant
The saturated fraction consists mainly of alkanes and cycloalkanes, making it an ideal component for easy lightening； Aromatic moieties can only undergo side-chain cleavage, hydrogen transfer, and condensation reactions; the aromatic ring itself cannot be broken. Therefore, monocyclic and bicyclic aromatics with long side chains remain excellent cracking feedstocks. It is a polycyclic compound with poor cracking properties, and serves as the precursor for the formation of coke.
Asphaltene and resins tend to produce coke; there is a lot of wax oil, while saturated and aromatic hydrocarbons yield more gasoline and diesel
