Field trials demonstrate the ability of novel scavenger to remove H2S from natural gas
Field demonstration trials of a novel method for removing hydrogen sulfide (H2S) from natural gas were recently completed in the Permian basin (Texas, USA). The trials demonstrated the ability of the technology, known as ECOTREAT®, to remove H2S from gas…
Spark ablation technology cuts iridium use by 90% in PEM water electrolysis
Proton-exchange membrane (PEM) water electrolysis holds significant promise for “green” hydrogen production, but broader adoption hinges on reducing dependence on costly platinum-group metals, such as iridium. A new production method for ultra-thin nanoporous layers developed by VSParticle B.V. (VSP; Delft,…
Microwave irradiation and ion exchange lower cost of battery upcycling
Approaches for recycling cathode active materials from used lithium-ion batteries generally face a tradeoff wherein recovering materials with the widest range of possibilities for re-use, such as pyrometallurgical methods, generally require high energy and long process times, while direct-recycling approaches…
Autonomous chemistry system identifies high-performing and tunable catalysts
Researchers at North Carolina State University (NCSU; Raleigh; www.ncsu.edu) and the University of North Carolina (Chapel Hill; www.unc.edu), with the support of Eastman Chemical Co. (www.eastman.com), have developed a closed-loop autonomous catalysis platform for identifying high-performing catalyst formulations and for…
Taming reactive radicals to streamline C-glycoside drug synthesis
Many widely used pharmaceuticals depend on a carbohydrate class known as C-glycosides, which are metabolically stable and acid-resistant. Although they can be made from common sugars like dextrose, C-glycosides have proven difficult to synthesize due to the preponderance of hydroxyl…
Ionomer-free plastic for vacuum packaging applications results from collaboration
Ionomers (polymers that can form cross-links between chains due to ionized functional groups) are often used for vacuum-packaged products because they have the strength needed to resist puncture and tearing when vacuum is applied. Due to material shortages for ionomer…
Patent granted on system for feeding biomass to high-pressure reactors
One of the challenges for biofuels manufacturing is reliably feeding low-density feedstocks into high-pressure reactors, because it is difficult to feed agricultural and forest residue, as well as municipal solid waste, into pressurized systems without bridging, compaction and flow instability.…
New insights into graphene oxide’s strengthening effects in concrete could accelerate commercial development
The nanomaterial graphene oxide (GO) has been investigated as a way to improve concrete strength, but reported results of GO’s effects have been inconsistent and detailed understanding of the mechanisms of its strength-enhancing effects has been elusive. New studies by…
Circular-loop recycling for disposable baby diapers demonstrated in Europe
Disposable baby diapers are a challenging waste stream, because the absorbent polymers, non-woven fibers and organic material prevent them from mechanical-recycling processes. However, a three-way partnership has demonstrated a circular system for chemical recycling of disposable diapers. The project, involving…
Pilot project debuts integrated hydrogen storage and transport using aqueous-salt technology
Hydrogen production is expanding across the globe, but hydrogen gas remains difficult and costly to store and transport, restricting its broader use. A pilot project in Germany is demonstrating for the first time a salt-based process for long-term hydrogen storage.…
