  • Patent number: 7981174
    Abstract: An exhaust particulate filter for an engine system includes an array of filter cartridges positioned within a shell, each of the cartridges having an electrically powered heating element coupled therewith. Exhaust gases are distributed among the cartridges according to a single distribution pattern, and the filter can be regenerated without diverting, dividing or bypassing exhaust gases from the filter. Other aspects include feedback control and feedforward control of regeneration based on sensing an electrical resistance property of each of the electrically powered heating elements.

  • Publication number: 20080078171
    Abstract: A filter for engine exhaust gases includes a filter media having an internal and external surface. A plurality of molecules of a fluid catalyst are attached to at least the internal and external surface of the filter media. The molecules of the fluid catalyst are configured to donate an oxygen atom to soot particles to activate the soot particles for regeneration.

  • Patent number: 7081231
    Abstract: The present disclosure pertains to a system and method for treatment of oxygen rich exhaust and more specifically to a method and system that combines non-thermal plasma with a metal doped ?-alumina catalyst. Current catalyst systems for the treatment of oxygen rich exhaust are capable of achieving only approximately 7 to 12% NOx reduction as a passive system and only 25–40% reduction when a supplemental hydrocarbon reductant is injected into the exhaust stream. It has been found that treatment of an oxygen rich exhaust initially with a non-thermal plasma and followed by subsequent treatment with a metal doped ?-alumina prepared by the sol gel method is capable of increasing the NOx reduction to a level of approximately 90% in the absence of SO2 and 80% in the presence of 20 ppm of SO2. Especially useful metals have been found to be indium, gallium, and tin.

  • Publication number: 20040228794
    Abstract: Disclosed herein are therapeutic agent carrier compositions that include a carrier comprised of a stimulus sensitive gel, fibrin, or combinations thereof, and a therapeutic agent such as an aqueous insoluble or confined radioisotope. Stimulus sensitive gels include thermally reversible stimulus-sensitive gels that are linear random copolymers of a [meth-]acrylamide derivative and a hydrophilic comonomer; thermogelling biodegradable polymers, which include biodegradable polymers including a linked polyethylene glycol (PEG) block and biodegradable polyester block; and enzymatically degradable polypeptide poylmers. In certain embodiments the therapeutic agent is a hydrothermally synthesized radioactive therapeutic agent, such a 90-yttrium phosphate colloid. Methods of making such carrier compositions and methods of using such carrier compositions to treat diseases such as cancer also are disclosed.

  • Patent number: 6565737
    Abstract: A method and apparatus for selectively removing oxygen from a gas stream containing NOx and oxygen by contacting the gas stream with an electrochemical cell made from an electrode consisting of La1-XMXFeO3, (where M is selected from the group consisting of Sr, Ba, Ca, and combinations thereof, and X is between 0.05 and 0.5), a solid oxide electrolyte and a counter electrode, wherein the La1-XMXFeO3 electrode is on one side of a solid oxide electrolyte, and a counter electrode is on the opposite side of the solid oxide electrolyte, and applying a voltage to the electrochemical cell. The apparatus is preferably employed in a two chambered NOx sensor utilizing solid electrolyte electrochemical cells, wherein an electrochemical cell capable of catalyzing oxygen reduction without catalyzing NOx decomposition is formed as integral to the first chamber.

  • Patent number: 6458414
    Abstract: A method for processing lanthanum oxide solids in an aqueous solution. An aqueous solution containing a partially soluble or insoluble salt forming anion is provided. A soluble lanthanum oxide solid is then added to the solution, and the anion is then reacted with at least a portion of the lanthanum in the lanthanum oxide solid, thereby forming a partially soluble or insoluble salt coating around the lanthanum oxide solid.
