  • Proton conducting membrane for fuel cells
    Patent number: 7195835
    Abstract: An ion conducting membrane comprising dendrimeric polymers covalently linked into a network structure. The dendrimeric polymers have acid functional terminal groups and may be covalently linked via linking compounds, cross-coupling reactions, or copolymerization reactions. The ion conducting membranes may be produced by various methods and used in fuel cells.

  • Autothermal hydrodesulfurizing reforming method and catalyst
    Patent number: 6967063
    Abstract: A method for reforming a sulfur-containing carbonaceous fuel in which the sulfur-containing carbonaceous fuel is mixed with H2O and an oxidant, forming a fuel/H2O/oxidant mixture. The fuel H2O/oxidant mixture is brought into contact with a catalyst composition comprising a dehydrogenation portion, an oxidation portion and a hydrodesulfurization portion, resulting in formation of a hydrogen-containing gas stream.

  • Method for the removal of ultrafine particulates from an aqueous suspension
    Patent number: 6153103
    Abstract: A method of separating ultra-fine particulates from an aqueous suspension such as a process stream or a waste stream. The method involves the addition of alkali silicate and an organic gelling agent to a volume of liquid, from the respective process or waste stream, to form a gel. The gel then undergoes syneresis to remove water and soluble salts from the gel containing the particulates, thus, forming a silica monolith. The silica monolith is then sintered to form a hard, nonporous waste form.
