Producing Hydrogen from Coal Via Catalytic/Chemical Looping Processes U.S. Patent Pending

This invention describes a novel catalytic method combined with a chemical looping process to produce a hydrogen (H2)-rich synthesis gas (syngas) stream free of the nitrogen from coal. The catalytic process uses reduced metal oxide/coal/steam to produce a H2-rich syngas stream that is free of nitrogen (N2) from coal while the chemical looping combustion (CLC) of fuel with the metal oxide is used for production of the heat required for the catalytic process. CLC processes also produce a concentrated stream of carbon dioxide (CO2) that is ready for sequestration. This technology is available for licensing and/or further collaborative research from the U.S. Department of Energy’s National Energy Technology Laboratory.

Challenge

Traditional coal gasification requires an expensive air separation unit to produce N2-free syngas. However, NETL’s novel catalytic process using reduced metal oxide/coal/steam does not require an air separation unit for production of nitrogen free syngas stream. Heat is traditionally produced via fuel combustion, which generates a CO2 stream mixed with N2. This stream requires expensive separation technologies for CO2 sequestration. The novel catalytic process uses the heat from CLC of fuel, which generates a sequestration ready CO2 stream. Integration of the processes, addressing contaminant issues and scaling up the technology for commercialization are necessary.

Novel Algorithm Enables Manufacture of Continuous Single-Crystal Fibers of Infinite Length U.S. Patent Pending

A patent-pending computer-control algorithm invented by the National Energy Technology Laboratory enables the manufacture of single-crystal optical fibers of potentially infinite length, with improved diameter control and faster growth, using a laser-heated pedestal growth (LHPG) system. These fibers can be used to fabricate sensors that can withstand the harsh environments of advanced energy systems. This technology is available for licensing and/or further collaborative research from NETL.

Challenge

Single-crystal optical fibers made of sapphire and other materials are only commercially available in short lengths of less than 2 meters. Using conventional technologies, length is limited by the finite size of the feedstock pedestal and equipment constraints that prevent supplying more feedstock material without compromising crystal quality. A robust technological solution is needed that allows replacement of the feedstock pedestal with minimum crystal defects and more consistent diameter for long single-crystal fibers. Other algorithms have been studied, but none has offered the ability to produce fibers of arbitrary length.

Novel Tri-Metallic Ferrite Oxygen Carriers Enhance Chemical Looping Combustion USPN 9,797,594

A patented technology invented at the U.S. Department of Energy’s National Energy Technology Laboratory enhances chemical looping combustion by providing tri-metallic ferrite oxygen carriers that offer greater durability and better reactivity than traditional oxygen carriers. Tri-metallic ferrite oxygen carriers also eliminate agglomeration issues, improve reduction rates, and offer similar costs when compared to traditional oxygen carriers, with convenient preparation using readily available materials. This technology is available for licensing and/or further collaborative research from NETL.

Challenge

Chemical looping combustion (CLC) is a promising technology for coal-derived energy production that involves combusting fuel in nearly pure oxygen to simplify carbon capture. In CLC systems, oxygen is introduced to the system via oxidation-reduction cycling of an oxygen carrier. Traditional oxygen carriers such as CuO, Fe2O3, NiO, and CoO have disadvantages including low reactivity (Fe2O3), low melting point and high agglomeration (CuO), and health and environmental concerns (NiO). The development of new oxygen carriers with enhanced performance characteristics is required for successful deployment of coal CLC processes.

Method for Enhancing Selectivity and Recovery in the Fractional Flotation of Flotation Column Particles USPN 7,992,718

Although research is currently inactive on the patented technology "Method for Enhancing Selectivity and Recovery in the Fractional Flotation of Flotation Column Particles," the technology is available for licensing from the U.S. Department of Energy’s National Energy Technology Laboratory (NETL).

Disclosed in this patent is a method of particle separation from a feed stream comprised of particles of varying hydrophobicity by injecting the feed stream directly into the froth zone of a vertical flotation column in the presence of a counter-current reflux stream. The current invention allows the height of the feed stream injection and the reflux ratio to be varied to optimize the concentrate or tailing stream recoveries desired based on existing operating conditions or other considerations. This novel method provides a high degree of particle collection with reduced carryover of lower hydrophobic or hydrophilic particles to the froth overflow, reduces or eliminates reliance on a clean wash-water supply, allows capture of coarse particles beyond the upper limiting size for liquid injection columns, allows capture of fine particles while mitigating the tendency of the low inertia particles to follow bubble streamlines and avoid capture, and provides other benefits over previously used methods of capture.

Spheroid-Encapsulated Ionic Liquids for Gas Separation USPN 9,050,579

An innovative approach has been developed allowing the use of high viscosity for gas separations. The method involves the encapsulation of ionic liquids (ILs) into polymer spheroids, taking advantage of the gas-absorbing properties and cost-effectiveness of ILs, while circumventing known IL viscosity issues. Significantly, the process permits optimization or ‘tuning’ of the IL-containing spheroids for specific gas separation applications.
