Methods for separation of oxygenates or other chemical components from fuels using chemical processes and separations including, but not limited to, onboard applications in vehicles. These separations may take place using a variety of materials and substances whereby a target material of interest is captured, held, and then released at a desired location and under desired conditions. In one set of experiments we demonstrated an enhancement in the separation of diaromatics by >38 times over gasoline and aromatics by >3.5 times over gasoline. This would give an advantage to reducing cold-start emissions, or emissions during transient conditions, in either gasoline or diesel.
