| 20090014357 | Method for removing nitrogen compounds from gasoline or diesel fuel using molecularly imprinted polymers - A method and product for removing nitrogen compound molecules from gasoline or diesel fuel includes exposing the gasoline or diesel fuel to a plurality of molecularly imprinted polymer beads (MIPS) that have receptor sites on the surfaces thereof that include imprints that match the physical shape of at least a portion of a nitrogen compound molecule. A quantity of the nitrogen molecules align with and adhere to some of the receptor sites and, accordingly, they are removed from the gasoline or diesel fuel producing a remediated or sweetened gasoline or diesel fuel. According to one embodiment, the MIPS are contained in an enclosure having a plurality of openings large enough to permit the solution to pass through and small enough so as to prevent the MIPS from passing through. According to another embodiment the MIPS are applied (i.e., coated) to the inside surface of a conduit and the gasoline or diesel fuel is forced or allowed to flow through the conduit thereby removing some of the nitrogen molecules therefrom. The MIPS are treated after use to remove a sufficient quantity of the nitrogen molecules from the receptor sites and are reused. | 01-15-2009 |
