    Abstract: Methods and apparatus for pre-treated ion exchange resins and their use in heat transfer systems, alternative power sources such as fuel cells, battery systems, and assemblies comprising such power sources. The apparatus may include a cooling system and a pre-treated ion exchange resin. The pre-treated ion exchange resin may include a corrosion inhibitor and/or antioxidant treated ion exchange resin. The cooling system may include a heat transfer fluid. The heat transfer fluid may include water, a glycol-based freeze-point depressant, and mixtures thereof. The glycol-based freeze-point depressant may include ethylene glycol, propylene glycol, 1,3-propanediol, and mixtures thereof. The cooling system may include an ion exchange unit. The ion exchange unit may include a pre-treated ion exchange resin, an untreated ion exchange resin, a basic anion resin, an acidic cation exchange resin, and mixtures thereof.

    Abstract: An anion exchange membrane is made by mixing 2 trifluoroMethyl Ketone [nominal] (1.12 g, 4.53 mmol), 1 BiPhenyl (0.70 g, 4.53 mmol), methylene chloride (3.0 mL), trifluoromethanesulfonic acid (TFSA) (3.0 mL) to produce a pre-polymer. The pre-polymer is then functionalized to produce an anion exchange polymer. The pre-polymer may be functionalized with trimethylamamine in solution with water. The pre-polymer may be imbibed into a porous scaffold material, such as expanded polytetrafluoroethylene to produce a composite anion exchange membrane.

    Abstract: Provided are a continuous crystal transformation and ion exchange device and process, belonging to the technical field of molecular sieve manufacturing. The continuous crystal transformation and ion exchange device comprises M+N reaction tanks which are in serial connection, wherein a feed opening of a latter reaction tank communicates with a discharge opening of a former reaction tank by means of a reaction solution circulation pipeline, and a discharge opening of an M+Nth reaction tank communicates with a feed opening of a first reaction tank by means of a reaction solution circulation pipeline. No more than M reaction tanks are used for a crystal transformation process, and no more than N reaction tanks are used for an ion exchange process. The method is used for preparing a finished zeolite molecular sieve product, and has the advantages of high exchange capacity, simple process, low cost and the like.
