Alright, I am trying to find LHV for a liquid fuel. Let's say the fuel is a type of gasoline. The first thing that came up to my mind was to perform elemental analysis, then calculate HHV using Dulong and Petit equation, then convert to LHV using this equation:
LHV = HHV – 2400 ( M+9H2) kJ/Kg
I know EDS is not an option, I also doubt whether GC-MS might be helpful.
I don't really know any other liquid fuel elemental analysis instruments. If someone's willing to share an insight, I'd be very grateful.
Thanks in advance
You would like to consult ASTM book for determination of calorific value of petroleum material through Bomb Calorimeter.
Zakiuddin Ahmed, is that the ASTM D240-02 you’re referring to?
I forgot to mention that I have the HHV for my fuel already. I just need to convert HHV to LHV. The thing is I don’t know the method to find hydrogen content if I were to use the equation I provided above.
To determine H content you need to perform a HCNS analysis (by elementary analyzer) or H-NMR.
