How to design a hydrofining unit to improve the cetane number of diesel?

There are now catalysts specifically designed to effectively increase the cetane number of diesel.
Diesel hydroprocessing technology and corresponding catalysts to improve cetane number
Modifiers are components that hydrogenate biphenyl and triphenyl rings to form monophenyl rings or break them down into alkylbenzenes, thereby increasing the cetane number of the catalyzed diesel components. n-Paraffin is an alkane and represents the hydrocarbon structure with the highest cetane number; it can only have its chains shortened or undergo minimal isomerization. So why is its cetane number so low? What is it, just a few? From a design perspective, post-finishing treatments are essential. I don’t know what other methods there are.
