Mercury Sorbent Delivery System for Flue Gas USPN 7,494,632

The Department of Energy’s National Energy Technology Laboratory (NETL) is seeking licensing partners interested in implementing United States Patent Number 7,494,632 titled "Mercury Sorbent Delivery System for Flue Gas."

Disclosed in this patent is NETL’s system for the removal of elemental mercury (Hg) (and other contaminants) from flue gas streams, which involves utilizing a layer of sorbent particles contained within the filter fabric of a filter bag in a flue gas scrubbing system. Gases generated from combustion sources such as coal gasifiers, coal-fired electrical generating plants, and ore smelters are candidates, especially if the gases already need particulate removal, and if cross-contamination of fly ash by-product by sorbent/mercury is to be avoided. More than 90 percent of elemental mercury was shown to be removed when activated carbon particles were tested in this process. The particle-loaded membranes may also act as oxidizers of the elemental Hg ahead of wet scrubbers. In addition, cleanup of aqueous waste streams is possible.

Regenerable Sorbents for CO2 Capture from Moderate and High Temperature Gas Streams USPN 7,314,847

The Department of Energy’s National Energy Technology Laboratory is seeking licensing partners interested in implementing United States Patent Number 7,314,847 titled "Regenerable Sorbents for CO2 Capture from Moderate and High Temperature Gas Streams."

Disclosed in this patent is NETL’s process for making a granular sorbent to capture carbon dioxide from gas streams. The sorbent is made by homogeneously mixing a reactive substrate containing an alkali metal with an alkaline earth metal-containing moiety to form a mixture; adding water to the mixture; and drying the mixture. After drying, the sorbent is placed in a container permeable to a gas stream. The sorbents produced by this method absorb up to 38 times more gas than current methods.

Method of Applying a Cerium Diffusion Coating to a Metallic Alloy USPN 7,553,517

The Department of Energy’s National Energy Technology Laboratory (NETL) is seeking licensing partners interested in implementing United States Patent Number 7,553,517 titled "Method of Applying a Cerium Diffusion Coating to a Metallic Alloy." This invention is applicable to advanced, next-generation power plant components; solid oxide fuels cells; heaters and heat exchangers; or any other application where oxidation-resistant metals are needed.

Disclosed in this patent is NETL’s robust, inexpensive process for increasing the oxidation resistance of nickel-based superalloys, as well as ferritic and austenitic stainless steels. The process involves applying a cerium oxide (CeO2) slurry to the metal surface, followed by heat treating to induce microstructural changes in the surface by cerium diffusion.

Laser Spark Distribution and Ignition System USPN 7,421,166

The Department of Energy’s National Energy Technology Laboratory (NETL) is seeking licensing partners interested in implementing United States Patent Number 7,421,166 titled "Laser Spark Distribution and Ignition System."

Disclosed in this patent is NETL’s laser spark distribution and ignition system, which reduces the high-power optical requirements normally needed for such a system by using optical fibers to deliver low-peak-energy pumping pulses to a laser amplifier or laser oscillator. Laser spark generators then produce a high-peak-power laser spark from a single low power pulse. The system has applications in natural gas fueled reciprocating engines, turbine combustors, explosives, and laser induced breakdown spectroscopy diagnostic sensors.
