Niobium-based anodes create high-speed lithium ‘highways’
By replacing traditional silicon or graphite anode materials with specially crystallized niobium, manufacturers can overcome some of the safety and power limitations of traditional lithium-ion batteries (LIBs). Echion Technologies Ltd. (Cambridge, U.K.; www.echiontech.com) has developed a proprietary mixed niobium-oxide active…
Electrostatic PFAS capture produces nearly zero waste
Increased concern around per- and polyfluoroalkyl substances (PFAS) in water is necessitating more robust mitigation techniques. There are many technologies that can effectively capture or destroy PFAS, but challenges remain surrounding large volumes of PFAS-laden solid waste and fluorinated byproducts.…
The Effects of Particle Size on Bulk-Solids Flow Properties
Understanding how particle size affects flow properties helps ensure reliable flow of materials between process steps Many industries utilize dry solid materials and powders (collectively referred to as bulk solids in this article) for producing and manufacturing products. It is…
Facts At Your Fingertips: Determining RTD in Non-ideal CSTR Reactors
In continuous processes, the properties and quality of the products depend on the residence time of different feed substances, and feed materials may not spend the same amount of time in a reactor. When designing equipment for continuous processes, it…
Two studies point the way to cleaner syngas-to-hydrocarbons processes
The production of commercially important hydrocarbons from synthesis gas (syngas; mixtures of H2 and CO) using the Fischer-Tropsch (F-T) process is a key strategy for making fuels and chemicals from a range of non-petroleum feedstocks. But F-T processes are relatively…
Enabling Clean Ammonia: Practical Lessons from a Full Plant Conversion
Low-carbon ammonia is an attractive driver for decarbonization of many product chains. Here are some practical insights from a legacy plant that was updated for cleaner ammonia production Ammonia production is under growing scrutiny as decarbonization becomes a global imperative.…
Powerful palladium “plugs” make this hydrogen-separating membrane more durable
Palladium is widely used in membrane applications because of its extreme selectivity for hydrogen. However, conventional palladium membranes can be damaged at the high temperatures required for many processes that generate hydrogen for various subsequent uses, including the manufacture of…
Nickel-based catalyst could allow recycling of mixed polyolefin waste
Among the major challenges facing efforts to chemically recycle common waste plastics is that many methods require a pure stream of a single type of polymer to be effective. Now, researchers at Northwestern University (NU; Evanston, Ill.; www.northwestern.edu), led by…
Dual-action nanocomposite combines adsorption and photocatalysis for wastewater treatment
Pharmaceutical residues, particularly from antibiotics, are extremely difficult to fully remove from wastewater using traditional bulk-treatment methods, wherein antibiotic compounds are often only partially broken down. Even at trace amounts, antibiotic fragments can accumulate and wreak havoc on natural ecosystems.…
