Abstract
Fuel compositions that are low sulfur and have adequate combustion quality are disclosed. An example fuel composition that is low sulfur may have the following enumerated properties: a sulfur content of about 0.50% or less by weight of the fuel composition; a calculated carbon aromaticity index of about 870 or less; a density at 15° C. of about 900 kg/m3 to about 1,010 kg/m3; a kinematic viscosity at 50° C. of about 100 centistokes to about 700 centistokes; and an estimated cetane number of about 7 or greater.
