i know the allowable percentage of benzene in gasoline according to Euro-6 specifications ( 1 vol. % ). Moreover, i need the percentage of ethyl benzene, Toluene , o,m and p xylene.
for European gasoline, there is no specific limit for ethylbenzene, toluene and xylènes. The only limit is set to the total aromatic content (35% vol maximum).
Exactly, i know this my sir. can i fin any specifications for ethylbenzene, toluene and xylènes for gasoline unlike Standard European regulations. thank you for your efforts.
There is no clear specification. Now you can find some "typical" fuel composition on publications. For instance, a quite old but interesting report of CONCAWE can be found at the following adress : https://www.concawe.eu/uploads/Modules/Publications/rpt_02-9-2003-01128-01-e.pdf
On page 27 you have some values of chemical composition.
With the increase of ethanol useage in Europe, the total aromatic concentration may be lower (less need of reforming in order to meet the Octane requirements), but the repartition may remain quite the same.
I can hardly express my gratitude and i am very nice to discuss with you
