Heat values of gas components 1

[geoffreydavies]

Hello all:
Looking for help to find a table of heat values for natural gas components that covers decanes ++
Thanks

I had no luck finding anything over C10 paraffins in my reference material. However, I did plot the various paraffin's heating values against their C/H ratios and got an excellent correlation.

Depending on the accuracy you need, this might be an option though extrapolating data always makes me somewhat nervous. However, the heat release from burning hydrocarbons directly related to the C and H content so this should be a valid approach.

Heats of combustion gas-gas in Btu/lb for the principal hydrocarbons, rounded and averaged from different sources:

C1 21,510
C2 20,420
C3 19,940
n-C4 19,600
n-C5 19,510
n-C6 19,400
n-C7 19,320
n-C8 19,260
n-C9 19,220
n-C10 19,180
H2S 6,150
H2 51,620
CO 4,350

The following Net Heats of Combustion (to form H₂O gas and CO₂ gas) in Btu per pound at 60 degrees F are from page 2 of "Data Book On Hydrocarbons" written by J.B. Maxwell and published by the D. Van Nostrand Company in 1950:

C1 21,500
C2 20,420
C3 19,930
nC4 19,670
nC5 19,500
nC6 19,240
nC7 19,160
nC8 19,100
nC9 19,050
nC10 19,020
nC11 19,000
nC12 18,980
