A hydrocarbon composition is provided containing: at least 5 wt. % of hydrocarbons having boiling point in the range from an initial boiling point of the composition up to 204° C.; at least 10 wt. % of hydrocarbons having a boiling point in the range from 204° C. up to 260° C.; at least 25 wt. % of hydrocarbons having a boiling point in the range from 260° C. up to 343° C.; at least 30 wt. % gram of hydrocarbons having a boiling point in the range from 343° C. to 538° C.; and at most 3 wt. % of hydrocarbons having a boiling point of greater than 538° C.; wherein the composition contains aromatic hydrocarbons including mono-aromatic hydrocarbons, di-aromatic hydrocarbons, and polyaromatic hydrocarbons, where the combined mono-aromatic hydrocarbon compounds and di-aromatic hydrocarbon compounds are present in a weight ratio relative to the polyaromatic hydrocarbon compounds of at least 1.5:1.0.
