Abstract:
1. A balanced unleaded fuel composition comprising: from about 2 vol. % to about 12 vol. % of a mixture of isoparaffins having 4 and carbon atoms; from about 51 vol. % to about 73 vol. % alkylate having an initial boiling range of from about 34.4° C. (94° F.) to about 93.9° C. (201° F.) and a final boiling range of from about 109° C. (228.2° F.) to about 223° C. (433.4° F.), the alkylate comprising isoparaffins having from 4 to 13 carbon atoms, about 60 vol. % or more of the isoparaffins having from 7 to 8 carbon atoms; from about 5 vol. % to about 15 vol. % of one or more alkanol having from about 2 to 4 carbon atoms; and from about 7 vol. % to about 30 vol. % of an aromatic component comprising a quantity of one or more alkylated benzene having from 7 to 12 carbon atoms and an amount of a C9 aromatic component having a boiling range of from 161.7° C. (323° F.) to about 178° C. (352° F.), the C9 aromatic component comprising aromatic compounds having from about 8 to 11 carbon atoms, about 50 vol. % or more of the aromatic compounds having 9 carbon atoms; wherein the balanced unleaded fuel composition exhibiting a pump octane rating of 100 or more, a T50 (maximum) of 104.4° C. (220° F.), and a T90 (maximum) of 165.6° C. (330° F.).
