Producing hydrogen via methane pyrolysis – termed ‘turquoise hydrogen’ – has thus far received less attention than ‘blue’ and ‘green’ H2, but it may offer advantages over both While the vast majority of current hydrogen production occurs by steam reforming…
Most polymeric membranes degrade during use, making them impractical for industrial separation processes. To solve this problem, researchers from the State University of New York at Buffalo (SUNY Buffalo; www.buffalo.com), with cooperation for scientists at Rensselar Polytechnic Institute, have created…
A new technology designed for improving the environmental footprint associated with processing liquid waste streams containing suspended or dissolved solids has been developed by Sedron Technologies (Sedro-Wooley, Wash.; www. sedron.com) and tradenamed Varcor. The technology separates, dries and sterilizes solid…
Scientists at École Polytechnique Fédérale de Lausanne (EPFL; Switzerland; www.epfl.ch) have synthesized the first ever metal-organic frameworks (MOFs) membrane with the thickness of just one unit cell. The ultrathin film yields record-high performance for the separation of hydrogen from nitrogen.…
The Vilsmeier reagent (VR), [(CH3)2 NCHCl]Cl, is necessary for producing a large range of pharmaceuticals, but it is unstable in air and is made from the toxic precursor phosgene (COCl2). A new flow-reactor system has been developed by Akihiko Tsuda,…
Electrolyzers are typically associated with the production of “green” hydrogen from water and renewable electricity, but a new device borrows from traditional electrolyzer principles to convert CO2 into propane. A team of researchers from the Electrochemical Energy Materials and Devices…
Construction is underway by AIR Co. (Brooklyn, N.Y.; www.aircompany.com) for a commercial demonstration plant capable of converting captured carbon dioxide into fuel-grade paraffins, as well as ethanol and methanol, in a single step. The facility will be a larger version…
Researchers at the Karlsruhe Institute of Technology (KIT; Germany; www.kit.edu) have developed a new class of materials — enzyme foams. Normally, foaming modifies the enzyme structure and enzymes lose their biocatalytic activity. The new protein foams, however, are said to…
Plant Watch OCI Global to double U.S. production capacity for ‘green’ methanol September 14, 2023 — OCI Global N.V. (Amsterdam, the Netherlands; www.oci-global.com) plans to double its green-methanol production capacity to approximately 400,000 metric tons per year (m.t/yr) in Beaumont,…
Covestro AG (Leverkusen, Germany; www.covestro.com) has developed a chemolysis process for recycling polycarbonate back into monomers. In laboratory trials, the process has been shown to recycle waste streams with more than 50% polycarbonate content into monomers, closing the loop to…
