Dear friends ;
I'm wondering please if there is a difference in chemical composition
between KEROSENE and JET A ?
Thanks a lot !
Regards !

No. Kerosene can be ATF if all the.requirements are met.

Dear Dana,
Mr.Rao is correct. JET A-1 is kerosene which already has less contaminant.
Some time kerosene from Distilation tower also able to be jet a-1 if the specification meet.
If the contaminant still not comply then you should add kerosene treater which called kero merox.
JET A-1 for example has to meet special requirement such as:
1. freezing point mush be low since when plane at 30000 feet surrounding temperature is low.
2. Existent gum. as we know gum may able to make pipeline clogged.
3. Distillation-end point. to make a plane fuel kerosene must not has high end point (i.e max 300 deg C)
4. still many parameter which need to comply for kero to be jet a1
Regards, Dani

Please note that Jet A (US) and Jet A-1 are different grades of Jet Fuels. Jet A is what US commercial flights use and has a higher spec on freeze point of -40 C whereas Jet A-1 is what commercial aviation in the rest of the world uses and has a freeze point spec of -47 C. This is primarily due to the predominance of Gasoline vs. Diesel economies in the two different economies.
Jet A-1 or Jet A in general is nothing but Kerosene with more stringent specs on Freeze point, Water content, particulates etc. So technically it is the same hydrocarbon stream (very broadly)
