Protein-binding process supports selective rare-earth element separation
Isolating and purifying rare-earth elements (REEs) is extremely challenging and energy-intensive due to the difficulty in separating chemically similar REE ions. Traditional separation methods require solvent extraction or chelating agents and produce large volumes of hazardous waste, all with little…
New plasma-powered process directly converts methane to graphene oxide
Researchers at Texas A&M University (College Station; www.tamu.edu) have developed a fundamentally new route to graphene oxide (GO) synthesis using non-thermal atmospheric plasma — a method that sidesteps the toxic chemicals and scalability limitations that often constrain conventional production approaches.…
Synthetic enzyme mimicry breaks open new aromatic reaction pathways
Mimicking enzyme-like behavior for synthetic chemistry is a growing field of exploration in sustainable chemical production, unlocking potential new reaction routes that eliminate waste and unwanted byproducts. A team of chemists from Penn State University (State College, Pa.; www.psu.edu) has…
Low-voltage, membrane-free electrolysis produces hydrogen and FDCA
A new approach to the traditional alkaline electrolyzers used to produce “green” hydrogen from water eliminates the membrane and introduces a new reaction mechanism at the anode, enabling the production of a high-value plastic precursor, 2,5-furandicarboxylic acid (FDCA). Developed at…
These “self-driving” bioreactor sensors are forging new fermentation frontiers
Ubiquitous in biomanufacturing, fermentation processes are complex and unpredictable when compared to traditional chemical-processing operations. From changing cell-growth rates to drifts in environmental conditions, typical control approaches can only react to predetermined setpoints rather than reliably maximize product output. A…
Sorbent-based ammonia-production system lowers cost and allows modularity
World-scale ammonia-production plants based on the Haber-Bosch process supply the ammonia for most of today’s agricultural fertilizer industry. But building new capacity for ammonia production is economically difficult because of the high capital expenditures needed for plants large enough to…
Offtake agreement inked for system that produces methanol from stranded methane economically
In late August, technology developer Emvolon, a spinout company from the Massachusetts Institute of Technology (MIT; Cambridge, Mass.; www.mit.edu), signed an offtake agreement with Freepoint Commodities LLC (www.freepoint.com) for methanol produced commercially via Emvolon’s technology starting in spring 2027. The…
Scaleup planned for system that can decarbonize furnace-based processes
Technology spun out from the University of Birmingham (www.birmingham.ac.uk) and developed by the startup PeroCycle Ltd. (Cambridge, U.K.; www.perocycle.com) is aimed at low-cost decarbonization of blast-furnace and direct-reduced-iron (DRI) steel-making operations, along with other furnace-based industrial processes, like glass-making. The…
Layered graphite membrane has internal structure to aid water separation from IPA
Isopropyl alcohol (IPA) is a key industrial solvent for the pharmaceuticals, electronics and fine chemicals sectors, among other uses, but methods for making IPA leave water-alcohol mixtures that need to be separated to achieve the purities required for industrial use.…
Refinery-grade crude oils can be made from biogenic waste using this technology
A pre-commercial plant is now providing operational data for eventual scaleup and industrial integration of a technology that generates refinery-grade crude oils from biogenic waste, such as agricultural and forestry waste and sewage sludge. The 12-ton/d demonstration plant (photo), built…
