Figure 11.7. Petroleum and synthetic fuel composition by carbon number for (a) Jet-A fuel (note that this
figure is in terms of mole fraction, unlike the other histograms); (b) and (c) from Jet-A derived
from traditional petroleum reservoirs and from shale-derived sources; (d)-(g) are fuels derived
from compressed natural gas; (h) is derived from coal; (i) is a fully synthetic coal-derived fuel
that incorporates synthetic aromatics; and (j) is an example of Hydrogenated Esters and Fatty
Acids (HEFA) jet fuel made from a blend of bio-SPK and petroleum jet fuel. Adapted from
(a) LeClercq and Aigner (2009); (b)-(c) ATDSR (1995); (d)-(h) Moses (2008); (i) van der
