Research is active on the development of metal ferrite oxygen carriers/catalysts for use in processes that convert carbon dioxide (CO₂) to carbon monoxide (CO) or synthesis gas by reforming or gasification. This invention is available for licensing and/or further collaborative research from the U.S. Department of Energy’s National Energy Technology Laboratory.

Challenge

A variety of approaches have been employed to harness CO₂ activation in order to produce useful products for chemical processes and to control greenhouse gas emissions. These approaches include catalytic dry reforming of methane, chemical looping dry reforming of fuel, and coal gasification with CO₂.

CO and synthesis gas are very useful precursors for various chemical processes and can be used as a fuel for energy production. In catalytic dry reforming, the production of syngas from CO₂ and methane is achieved in the presence of a catalyst that offers several advantages, such as mitigation of greenhouse gases emissions and conversion of CO₂ and methane into syngas which can be used to produce valuable downstream chemicals. In chemical looping dry reforming, oxygen from an oxygen carrier or metal oxide is used for partial combustion of methane or coal to produce syngas or CO. The reduced oxygen carrier is then oxidized using CO₂ to produce CO and oxidized oxygen carrier. In coal gasification with CO₂, production of syngas from coal is achieved through the reaction of coal with CO₂ instead of air or steam, which can be enhanced by the presence of metal oxide/metal promoters. Since the gasification process does not require steam, significant cost reductions would be expected. However, finding low-cost and efficient catalysts/oxygen carriers for these processes has been a major challenge, limiting their commercial success.

This invention describes the synthesis and application of nanostructured copper (Cu) catalysts that selectively convert carbon dioxide (CO₂) into carbon monoxide (CO). This technology is available for licensing and/or further collaborative research from the U.S. Department of Energy’s National Energy Technology Laboratory.

Challenge
The electrochemical CO₂ reduction reaction (CO₂RR) is an appealing strategy for addressing man-made CO₂ emissions because it can leverage excess renewable energy to produce carbon-neutral chemicals and fuels. However, the economic viability of large-scale CO₂RR systems will depend on the ability to selectively and efficiently form desirable products. Because it is earth-abundant and can produce a variety of products, Cu is a popular CO₂RR catalyst. Unfortunately, the wide product distribution of Cu introduces inefficiencies in the form of chemical separation steps.

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.

Challenge
BIAS sorbents demonstrate high CO₂ capture capacity and thermal stability over multiple steam regeneration cycles and represent a promising approach for CO₂ removal from a variety of source points, including coal and natural gas combustion power plants. Bench- and pilot-scale testing have demonstrated the feasibility of commercial-scale BIAS sorbents. However, full commercialization of BIAS sorbents requires pelletization. Commercially available silica typically serves as the support for amine-based particle sorbents, yet these materials are not commercially feasible due to their relatively low mechanical strength and difficult management in dynamic reactor systems. Thus, the development of an economical method of fabricating a strong silica-supported BIAS pellet is a primary concern.

Research is active on a method to convert methane into synthesis gas using mixed metal oxides. The resulting syngas could be used to manufacture more valuable chemicals. This technology is available for licensing and/or further collaborative research from the U.S. Department of Energy’s National Energy Technology Laboratory.

Challenge

Natural gas (NG), which is composed primarily of methane, is one of the most abundant, low-cost carbon-containing feedstocks available. The economically available route to produce valuable chemicals from methane is via synthesis gas followed by different chemical routes to manufacture the desired chemicals. In a large-scale industrial plant, the production of syngas accounts for a large part of the total costs. Therefore, it is important to develop more efficient and cost-effective methods for the conversion of methane to syngas.

The invention is a method for sensing the H₂ concentration of a gaseous stream through evaluation of the optical signal of a hydrogen sensing material comprised of Pd- or Pt-based nanoparticles dispersed in a matrix material. The sensing layers can also include engineered filter layers as the matrix or as an additional layer to improve H₂ selectivity. This technology is available for licensing and/or further collaborative research from the U.S. Department of Energy’s National Energy Technology Laboratory.

Challenge
The ability to selectively sense H₂ is critically important for a broad range of applications spanning energy, defense, aviation, and aerospace. One of the most significant needs is for sensors that are capable of leak detection of H₂ at levels up to the lower explosive limit. Additional applications of hydrogen sensors requiring operation at elevated temperatures include monitoring of hydrogen in metallurgical processes as well as monitoring the composition of fuel gas streams in power generation technologies such as gas turbines and solid oxide fuel cells. Measurements of H₂ levels dissolved in transformer oil can also enable condition-based monitoring to provide early detection of potential failures with large associated economic and environmental impacts.
