The composition of the feedstock and, in particular, its content of direct precursors: naphthenes (cyclanes) and aromatic compounds are important parameters. To measure the ability of a feedstock to produce an aromatic gasoline, we first used the characterization factorKUOP (table 4).
We currently prefer to use the sum :N + 2A
with :
N
:
naphthenes mass content (in %)
A
:
aromatic hydrocarbon content.
Theoretically, the higher the amount of direct precursors (N + 2A, generally ranging from 30 to 80) in the feedstock, the higher the possible yield of aromatic compounds. However, with today's...
