US Patent:
6712866, Mar 30, 2004
Filed:
Sep 24, 2001
Appl. No.:
09/961752
Inventors:
Stephen F. Paul - Princeton NJ
Assignee:
Stephen Paul - West Orange NJ
International Classification:
C10L 118
US Classification:
44352, 44451, 44452
Abstract:
A spark ignition motor fuel composition consisting essentially of: a hydrocarbon component containing one or more hydrocarbons selected from five to eight carbon atoms straight-chained or branched alkanes, wherein the hydrocarbon component has a minimum anti-knock index of 65 as measured by ASTM D-2699 and D-2700 and a maximum dry vapor pressure equivalent (DVPE) of 15 psi (one atmosphere (atm. )) as measured by ASTM D-5191; a fuel grade alcohol; and a co-solvent for the hydrocarbon component and the fuel grade alcohol; wherein the hydrocarbon component, the fuel grade alcohol and the co-solvent are present in amounts selected to provide a motor fuel with a minimum anti-knock index of 87 as measured by ASTM D-2699 and D-2700, and a maximum DVPE of 15 psi (1 atm. ) as measured by ASTM D-5191, and wherein the fuel composition is essentially free of olefins, aromatics, and sulfur. A method for lowering the vapor pressure of a hydrocarbon-alcohol blend by adding a co-solvent for the hydrocarbon and the alcohol to the blend is also disclosed.
