  • Patent number: 7901565
    Abstract: A method of reforming a sulfur containing hydrocarbon involves contacting the sulfur containing hydrocarbon with a sulfur tolerant catalyst containing a sulfur tolerant precious metal and a non-sulfating carrier so that the sulfur tolerant catalyst adsorbs at least a portion of sulfur in the sulfur containing hydrocarbon and a low sulfur reformate is collected, and contacting the sulfur tolerant catalyst with an oxygen containing gas to convert at least a portion of adsorbed sulfur to a sulfur oxide that is desorbed from the sulfur tolerant catalyst.

  • Patent number: 7901940
    Abstract: A method is provided for measuring the concentration of a catalytic clement in a fuel cell powder. The method includes depositing on a porous substrate at least one layer of a powder mixture comprising the fuel cell powder and an internal standard material, ablating a sample of the powder mixture using a laser, and vaporizing the sample using an inductively coupled plasma. A normalized concentration of catalytic element in the sample is determined by quantifying the intensity of a first signal correlated to the amount of catalytic element in the sample, quantifying the intensity of a second signal correlated to the amount of internal standard material in the sample, and using a ratio of the first signal intensity to the second signal intensity to cancel out the effects of sample size.

  • Patent number: 7875238
    Abstract: The invention pertains to a device for generating aqueous chlorine dioxide solutions when the device is contacted with liquid water. The device comprises an alkali metal or alkaline earth metal chlorite, e.g., sodium chlorite, and a chemical reagent comprising an acid or a material capable of releasing an acid upon exposure to liquid water, e.g., sodium bisulfate. The chlorite and the reagent are either combined as a mixture or are disposed as separate components adhered to the surface of one or more substrates. Upon exposure to liquid water, the chlorite and the reagent produce boundary layers. The chlorite and the reagent are disposed upon, and adhered to, the surface(s) of the substrates in a manner such that upon exposure to liquid water, the chlorite boundary layer comes into contact with the reagent boundary layer to thereby produce an aqueous chlorine dioxide solution.

  • Patent number: 7709135
    Abstract: A method is provided for recovering a catalytic element from a fuel cell membrane electrode assembly. The method includes grinding the membrane electrode assembly into a powder, extracting the catalytic element by forming a slurry comprising the powder and an acid leachate adapted to dissolve the catalytic element into a soluble salt, and separating the slurry into a depleted powder and a supernatant containing the catalytic element salt. The depleted powder is washed to remove any catalytic element salt retained within pores in the depleted powder and the catalytic element is purified from the salt.
