<P>PROBLEM TO BE SOLVED: To provide a gasoline composition that does not contain an oxygen-containing base material but excellently prevents generation of turbidity, and is excellent in environmental performance in consideration of the importance of environmental issues. <P>SOLUTION: (A) The gasoline composition comprises 10-50 vol.% of a catalytically reformed gasoline base material (I) or 10-50 vol.% of a catalytically reformed gasoline base material (II), wherein: the gasoline base material (I) has an aromatic composition in a predetermined ratio and has T10 and T90 at predetermined temperature; and the gasoline base material (II) has an aromatic composition in a predetermined ratio and has T10 at predetermined temperature, both ratio and temperature being different in range from those in the base material (I), and further has T90 at predetermined temperature that is in the same range as that of the base material (I). (B) The gasoline composition further comprises 10-60 vol.% of a catalytically-cracked gasoline that has an unsaturated hydrocarbon composition in a predetermined ratio and has T10 and T90 at predetermined temperature. (C) The gasoline composition has a predetermined Reid vapor pressure, research octane number, distillation properties, and compositions. <P>COPYRIGHT: (C)2013,JPO&INPIT |
