OXYGENATED BUTANOL GASOLINE COMPOSITION HAVING GOOD DRIVEABILITY PERFORMANCE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a butanol-containing gasoline blend which has good cold start and warm-up driveability characteristics.SOLUTION: A butanol gasoline blend is formed so that it has a value of low butanol driveability index (LBDI) equal to the linear combination a1T10+a2T50+a3T90+a4EtOH+BuOH (a5-a6E200) below the maximum limit for driveability index (DI) for a specific class of gasoline, wherein the total weighted demerits of the butanol gasoline blend is less than about 40.SELECTED DRAWING: None
