|Encapsulation Method for More Durable Reactive Materials||U.S. Patent Pending||
This invention describes a method of encapsulating reactive materials (i.e., catalyst, sorbent or oxygen carrier) within a porous, unreactive, strong outer layer to increase attrition resistance while retaining sufficient reactivity. This technology is available for licensing and/or further collaborative research from the U.S. Department of Energy’s National Energy Technology Laboratory.
Processes that involve fluidized bed or transport reactors require pellets with high attrition resistance because the pellets move continuously in the reactor during operation. Loss of pellets due to attrition contributes to high replacement costs and operational difficulties. Most processes that involve catalyst, sorbents and oxygen carriers operate in fluidized beds or circulating fluidized beds and require high attrition resistance for long-term operations. In addition, loss of reactive materials with low melting points, such as CuO, due to agglomeration is an issue. Pellets with high attrition resistance are needed to combat against loss of reactive materials.
|Streamlining The Process To Extract Lithium, Rare Earth Elements From Natural Brines||U.S. Patent Pending||
Research is active on the development and refinement of a process for the extraction of lithium (Li) and rare earth elements (REEs) from natural brines. This invention is available for licensing and/or further collaborative research from the U.S. Department of Energy’s National Energy Technology Laboratory.
Current leading technology to generate materials from natural brines requires a series of football field-sized slow evaporation ponds, as well as lengthy leaching, which takes approximately 18-24 months after leaving the well. Concentration processes of the selected materials require repeated pumping from one evaporation pond to another, followed by long-distance transportation (added expenses and carbon emissions) to a processing plant that generates the selected compounds by multiple carbonation steps by leaching. Current carbonation processes require various solid additives, including soda ash, lime, hydrochloric acid, organic solvent, sulfuric acid and alcohol. Several tons of additives may be required to produce only a ton of targeted material. Therefore, current operations are considered to be costly and environmentally harsh.
|Improved Pelletized Immobilized Amine Sorbents for CO2 Capture||USPN 10,065,174; USPN 10,603,654;||
This invention describes basic immobilized amine sorbents (BIAS) with improved pelletization process and formulation for use in CO2 capture processes. This technology is available for licensing and/or further collaborative research from the U.S. Department of Energy’s National Energy Technology Laboratory.
|Polyphosphazene Blends for Gas Separation Membranes||U.S. Patent Pending; USPN 7,074,256||
These technologies are high-performance CO2 separation membranes made from polyphosphazene polymer blends. NETL’s technology was originally developed to aid in separating CO2 from flue gas emitted by fossil-fuel power plants. The NETL membrane is cross-linked chemically using low intensity UV irradiation, a facile technique that improves the membrane’s mechanical toughness compared to its uncrosslinked polyphosphazene constituents. Membranes fabricated with this technique have demonstrated permeability of up to 610 barrer, with CO2/N2 selectivity in excess of 30, at a practical separation temperature of 40°C. NETL’s patent-pending technology is being bundled with Idaho National Laboratory’s (INL) patented technology, with NETL handling licensing. NETL would work with a potential licensee and INL to license the technology.
|Improved Rare Earth Element Extraction Method from Coal Ash||U.S. Patent Pending (provisional patent application)||
This invention describes an improved method for extracting rare earth elements (REEs) from coal ash at ambient temperatures. This technology is available for licensing and/or further collaborative research from the U.S. Department of Energy’s National Energy Technology Laboratory.
Current methods and technologies for REE extraction from ore and other sources can be hazardous and expensive to implement without harming the environment or workers. For example, common practices employ high temperatures and strong acids or bases. This technology seeks to overcome these and other issues with current REE extraction methods by turning to a material that is currently viewed as a waste – coal ash.
|Downhole Laser System With an Improved Laser Output Production and Data Collection||U.S. Patent Pending (non-provisional patent application)||
This patent-pending technology establishes a novel system and method for laser induced breakdown spectroscopy (LIBS) applications. The technology is available for licensing and/or further collaborative research from the U.S. Department of Energy’s National Energy Technology Laboratory.
Low-cost, efficient monitoring of remote locations has and continues to be highly sought in the industry. For example, drilling production or injection wells for oil/gas extraction or carbon dioxide (CO2) storage always has the potential for leakage into the surrounding formations and environment. The ability to measure the subsurface fluids in and around the injection/production area before and after subsurface activities becomes more important when there is a suspected leak. Current downhole monitoring systems rely on bulk parameters such as pH and conductivity. Lab based systems can provide trace element measurements of subsurface fluids but require fluids to be taken from the field and digested prior to measurement. A system that can provide trace element measurements in real time while deployed in the subsurface is potentially of great value.
Current diode pumped solid state (DPSS) laser systems used for laser induced breakdown spectroscopy applications in fluid system measurements have numerous limitations. First, the systems are susceptible to dimensional changes caused by temperature and pressure swings in fluctuating environments in downhole applications. A second issue is the size of the laser spark that is produced in the fluid for measurements affecting signal strength. The third issue is the efficient collection and transmission of the plasma emission for analysis.
