6. Average reforming performance
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 factorK UOP (table 4 ).
We currently prefer to use the sum :
with :
- N :
-
naphthenes mass content (in %)
- A :
-
aromatic hydrocarbon content.

Average reforming performance
Bibliography
Economic data
In 2000, worldwide catalytic reforming capacity stood at 530 Mt/year, corresponding to 660 plants in operation worldwide.
In 2000, worldwide production capacity for aromatic hydrocarbons was 40 Mt/year for benzene, 21 Mt/year for toluene and 34 Mt/year for xylenes, with catalytic reforming and steam cracking of petroleum cuts being the two main production routes. At that date, reforming accounted...
Catalyst manufacturers
The global market for catalytic reforming catalysts in 2000 is estimated at around 5,000 t.
As a result of mergers and acquisitions and withdrawals, there are now around 5 catalyst manufacturers, marketing some 40 different products.
The main ones are :
UOP (Union Oil Products)
Procatalysis
...
User industries
There are around 660 catalytic reforming plants in 770 refineries worldwide. In short, all major refineries have a reforming unit, and the industrialists are therefore all types of refiner, and in particular :
the major groups: Exxon-Mobil, Shell, BP, Chevron-Texaco and TotalFinaElf;
national companies: Pemex, Saudi Aramco, Sonatrach... ;...
