  • Patent number: 8197778
    Abstract: Sulfur dioxide (SO2) is removed from a carbon dioxide feed gas by maintaining the feed gas at elevated pressure(s) in the presence of oxygen (O2), water and NOx for a period of time sufficient to convert SO2 to sulfuric acid and NOx to nitric acid and produce SO2-depleted, NOx-lean carbon dioxide gas. The invention resides in separating the sulfuric and nitric acids from said SO2-depleted, NOx-lean carbon dioxide gas, and then neutralizing the acids by reaction with an alkaline sorbent in an acid/sorbent reactor system to produce sorbent-derive sulfate. The method has particular application in the removal of SO2 and NOx from flue gas produced by oxyfuel combustion of a carbonaceous fuel.

  • Patent number: 8187708
    Abstract: The disclosure provides methods for preparation of multiphasic micro-components, such as core-shell or anisotropic (e.g., Janus) multiphasic particles with well-defined structures using electrohydrodynamic co-jetting of two polymer solutions containing polyelectrolytes. Suitable polyelectrolytes include polyacrylic acid (PAA), poly(acrylamide acrylic acid (PAAm), and/or poly(acryl amide-co-acrylic acid) (PAAm-AA), sodium polystyrene sulfonate (PSS), polyethylene imine (PEI), polypeptides, copolymers and combinations of these. Control of certain variables, such as relative conductivities of the two jetting solutions, controls the particle morphologies formed, leading to a predetermined phase orientation for the same polymer system. In certain aspects, after cross-linking, core-shell particles are stable in aqueous solutions and exhibit reproducible swelling behavior, while maintaining the original core-shell geometry.

  • Patent number: 8187568
    Abstract: A method and system produce a synthesis gas from a biogas. The method provides a more economic process control and a higher yield. For this purpose hydrogen sulfide and carbon dioxide of the biogas are nearly completely separated in separate cleaning steps before a catalytic conversion of the biogas, wherein hydrogen sulfide is biologically removed by the admixture of oxygen and/or oxidation agents containing oxygen. The oxygen, or the oxidation agent, is dosed such that an excess of oxygen of at least 1.0 vol.-% is present in the cleaned biogas (methane gas). The biogas is concentrated without any dehumidification, heated, and mixed with superheated steam. Due to the excess of oxygen, thermal energy is additionally created during the reforming process by an exothermal oxidation of oxygen contained in the biogas together with hydrogen in the catalyst bed for the endothermal conversion of methane to the synthesis gas.

  • Patent number: 8182599
    Abstract: A configuration in which particles of pitch 2 having a softening point in the range of 70 to 200° C. and a diameter equal to or smaller than 30 ?m are held on the surfaces of particles of a refractory raw material 3 having a diameter equal to or smaller than 50 ?m is employed. This pitch-containing refractory raw material 1 can be used with the pitch being in a fine-particle form without any aggregation even after the long-term storage. Using it as a part of a raw material formulation allows the fine particles of pitch to be uniformly dispersed during the mixing or kneading process. The resulting carbon-containing refractory has an excellent corrosion resistance. It also provides suppressed increase in the Young's modulus while maintaining the level of strength, thereby being excellent in thermal spalling resistance even with the carbon content ratio being low.

  • Patent number: 8173101
    Abstract: The invention relates to a method for removing heavy metal ions from the lattice of tectosilicates or phyllosilicates, especially from zeolite mineral, particularly clinoptilolite, by exchanging ions with calcium ions. According to the inventive method, the zeolite rock is brought in contact with hydrochloric and ammonium-containing solutions in a chain of exchange reactors such that a large part of the cations of the lattice are replaced with ammonium ions, and the ammonium ions located in the lattice are replaced with calcium in a basic calcium hydroxide solution. The ammonium or ammonia used in the process is conducted in the circuit by binding the same in hydrochloric acid as an ammonium ion from the exchange solutions by conveying anhydrous ammonia and can be fed back to the exchange solution. The ions from the lattice that are exchanged are essentially precipitated as phosphate, carbonate, or hydroxide.
