Why does the cetane number of charred wood be higher than that of accelerated combustion wood?

As the title suggests, I would appreciate it if experts could offer some guidance. It would be best to analyze it from the perspective of the production principles. Thank you in advance.
The raw materials are different, and the reaction principles are also different
Due to different reaction principles, catalyzed diesel contains more polycyclic aromatic hydrocarbons; during the coking process, these polycyclic aromatic hydrocarbons coking. The reason for the low cetane number of diesel is the issue of aromatic content; aromatics have a high density, and cetane value is the ratio of boiling point to density, so the higher the density, the lower the value.
