The invention is a new type of amine-based sorbent material that has increased affinity towards heavy metal capture, from a variety of sources that exceeds the existing amine-sorbent ability by greater than 50%. This invention involves use of a polyamine that is chemically tethered to the surface of a solid silica support through use of a crosslinker and further stabilized through hydrogen bonding with a linker/cross linker. These sorbents can be used for the capture of heavy metals from a variety of aqueous sources. 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 US Resource Conservation and Recovery Act (RCRA) gave the US Environmental Protection Agency the authority to establish and enforce regulatory policies and toxicity limits regarding Arsenic (As), Cadmium (Cd), Chromium (Cr), Lead (Pb), Mercury (Hg), Selenium (Se), and other metals. Many of these metals present a distinct challenge for capture because they are most commonly present in the polyatomic oxy-anion form. Sources for most of these contaminant metals include flue gas desulfurization (FGD) wastewater streams. These streams result from the treatment of fossil fuel-derived, post combustion flue gas with aqueous-based technologies. The well-known and widespread contamination of metals in drinking water and other terrestrial water sources through natural processes or human activity, demands remediation. In addition, radioactive pollutants in aqueous form have raised concerns about exposure levels in the nearby communities because of fears that these fission products could make their way into the food chain.

This invention describes a system and method for detecting corrosion in natural gas pipelines using an optical platform or a wireless platform. 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 U.S. Energy Information Administration states that natural gas accounts for nearly 30 percent of energy consumption in the United States. More than 300,000 miles of natural gas transmission and gathering lines deliver this valuable energy source to consumers. Like any energy infrastructure, this network of pipelines requires significant maintenance costs. In the case of natural gas pipelines, corrosion accounts for around 25 percent of incidents over the last 30 years, 61 percent of which was caused by internal corrosion.

The corrosion-related annual cost for such incidents amounts to $6 to $10 billion in the United States each year. Therefore, a need exists to monitor corrosion inside of the gas pipelines to implement corrosion mitigation and control before any failure.

This novel patent-pending methane conversion technology employees microwave-assisted catalysis for chemical conversion. 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, primarily composed of methane, is a cheap and abundant domestic resource that can be converted to a wide range of products including liquid transportation fuels and a wide range of chemical intermediates. However, traditional methods of converting methane to valuable chemicals first require it to be converted to synthesis gas.

A direct, one-step, method to convert the methane would have significant advantages over current indirect methods, including reduced costs and increased yields, but several technology barriers must first be overcome. Microwave-assisted catalyst reactions can provide a viable direct method for overcoming these barriers.

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.

Challenge
As China currently controls the supply and prices of almost all the world’s REEs, developing a domestic supply is critical for the continued manufacturing of technologies that support nearly all modern devices, including critical systems for energy and national defense. REE extraction efforts from domestic sources of coal and coal-related resources have emerged as a viable solution, but successful methods must be both cost-effective and environmentally friendly.

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.
