Abstract

Disclosed is a method that uses a nanotube with a chemical "gate" within it, designed to enable only certain types of molecules to pass through. Benefits include a solution that provides a very low power separation of desired molecules from a chemical stream.

Chemical Purification Using Nanotubes

Disclosed is a method that uses a nanotube with a chemical “gate” within it, designed to enable only certain types of molecules to pass through. Benefits include a solution that provides a very low power separation of desired molecules from a chemical stream.

Background

The disclosed method combines well known physical effects (i.e. chemical gates) with a new technology (nanotubes) to provide a novel means of purifying chemicals.

General Description

The disclosed method places one end of the nanotube into a reservoir of working fluid or gas, (e.g. water, a solvent, or an impure version of the molecule being purified), then exposing the other end to an environment that causes either expansion or evaporation of the selected molecules; this causes a selective movement from the reservoir towards the expansion environment. Because only the desired molecules pass the “gate”, purification occurs, resulting in only the selected molecules being present on the expansion side of the nanotube
(see Figure 1).

Bundles of these nanotube assemblies (made to any appropriate size) can serve as the interface between portions of any appropriate chemical separation process, and can provide a very low power separation of desired molecules from a chemical stream.

Advantages

The following are advantages of the disclosed method:

§         A low power separation provides efficiencies in current industrial processes

§         No pollutants are generated as a consequence...
