Abstract:
1. A method for producing a butanol gasoline blend having good cold start and warm-up (CS&W) driveability performance comprising: (a) providing at least one biologically-sourced butanol isomer; (b) blending the at least one biologically-sourced butanol isomer with gasoline to form a butanol gasoline blend, the butanol gasoline blend having a specific ASTM D4814 Table 1 vapor pressure/volatility class; (c) determining a high butanol driveability index (HBDI (d) optionally adjusting the amount of gasoline and the at least one biologically-sourced butanol, or any combination thereof, such that the value of HBDI
