Methane pyrolysis catalyst Catalytic methane pyrolysis (CMP) is an attractive route to producing hydrogen, because rather than generating CO2, the process produces solid carbon, which can be made in valuable forms that could offset the cost of hydrogen production. However,…
This integrated technology effectively destroys PFAS — even short-chain compounds
The prevalence of the various per- and polyfluoroalkyl substances (PFAS) — compounds that are notoriously difficult to break down — in the water supply is causing global concern. A new partnership between Element Six (Oxford, U.K.; www.e6.com) and Lummus Technology…
Recycling process allows fast depolymerization of post-consumer mixed textiles
Recycling rates for post-consumer textile waste are very low (<0.5%) because the fabrics often consist of tightly interlaced synthetic and natural fibers that require costly sorting and separation processes, and because they often contain dyes and additives that must be…
First industrial demonstration of plasma-based CO2 conversion
Plasma technology is being explored as an avenue for many molecular conversions, such as methane reforming. Now, for the first time, a plasma-based CO2-conversion technology is being demonstrated industrially. The proprietary technology, developed by D-CRBN (Antwerp, Belgium; www.d-crbn.com), is being…
Biofuels production via co-fermentation of sugar and CO2 takes a step forward
Co-fermentation processes that can consume both sugars and CO2 are emerging as a promising technology to enhance product yield and reduce emissions in biofuels production. A team of scientists at Oklahoma State University (Stillwater, Okla.; www.okstate.edu) are working to accelerate…
Generalizable deep-learning technique for elucidating catalyst reaction mechanisms
Artificial intelligence techniques have great potential in generating insights into catalytic reaction mechanisms, opening the door to more selective and efficient catalysts. However, using machine-learning (ML) in a general way to study chemical reactions is challenging because broad approaches aimed…
Researchers use cellulose nanofibrils in 3D-printed concrete
A research team at the University of Virginia School of Engineering and Applied Science (Charlottesville, Va.; engineering.virginia.edu) is the first to explore how an emerging plant-based material, cellulose nanofibrils, could amplify the benefits of 3D-printed concrete technology. “The improvements we…
Pilot plant produces climate-friendly cement clinker
Concrete production is responsible for 6–9% of global anthropogenic CO2 emissions. “The largest contribution to that comes from the production of cement, a precursor product,” says Peter Stemmermann from the Institute for Technical Chemistry (ITC) at the Karlsruhe Institute of…
New structured packing introduced at Achema
At Achema 2024 (Frankfurt, Germany; June 10–15), Sulzer Chemtech (Winterthur, Switzerland; www.sulzer.com) revealed MellapakEvo (photo), the latest addition to its structured-packing product family. The MellapakEvo structured packing has been developed to enhance the efficiency and capacity of distillation columns, maximizing…
Cyanobacteria mineralize CO2 into biogenic construction materials
Researchers from the Fraunhofer Institute for Ceramic Technologies and Systems (IKTS; www.ikts.fraunhofer.de) and the Fraunhofer Institute for Electron Beam and Plasma Technology (FEP; both Dresden, Germany; www.fep.fraunhofer.de) are introducing an eco-friendly, biologically induced method of producing biogenic construction materials as…
