Patent number: 11168275Abstract: 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.Type: GrantFiled: October 17, 2019Date of Patent: November 9, 2021Assignee: BATTELLE MEMORIAL INSTITUTEInventors: John T. Bays, Katarzyna Grubel, David J. Heldebrant, John C. Linehan

Patent number: 10773205Abstract: A class of water lean, organic solvents that can bind with various acid gasses to form acid gas bound molecules having a high degree of intramolecular hydrogen bonding which enables their use as regenerable solvents for acid gas capture. Unlike the other devices described in the prior art, the present invention takes advantage of shortened distances between the portions of the molecule that form hydrogen bonds within the structures when loaded with an acid gas so as to create a molecule with a higher internal bonding affinity and a reduced proclivity for agglomeration with other molecules.Type: GrantFiled: August 15, 2019Date of Patent: September 15, 2020Assignee: BATTELLE MEMORIAL INSTITUTEInventors: Phillip K.
