The ability to precisely control the molecular structure of polymer membranes could expand their use in challenging separations, such as the purification of xylene isomers. Using highly selective membranes that can be operated at ambient conditions to separate such hydrocarbons…
Last month, Climeworks (Zurich, Switzerland; www.climeworks.com) started operations of Orca, said to be the world’s first and largest climate-positive direct air capture (DAC) and storage plant. Located in Hellisheiði, Iceland, the Orca plant has a capturing capacity of 4,000 ton/yr…
A feasibility study is underway for the world’s first commercial facility that integrates direct air capture (DAC) of atmospheric carbon dioxide with gas fermentation of CO2 and production of aviation fuels. LanzaTech (Chicago, Ill.; www.lanzatech.com) and Carbon Engineering (Squamish, B.C.;…
Runaway polymerizations of acrylic monomers can lead to catastrophic fires and explosions in production plants and storage terminals, as well as during transportation. Special chemical products called shortstop inhibitors are used to minimize the likelihood of runaway polymerization reactions. A…
Until now, manufacturing polymer-electrolyte membrane fuel cells (PEMFCs) that are small, light and capable of mechanical movement has been challenging using conventional methods. PEMFCs are composed of end plates, bipolar plates, gaskets, membrane-electrode assemblies (MEAs) and other assembly parts, of…
Conventional processes for manufacturing battery electrodes use toxic solvents and require a lot of space and energy. In contrast, DRYtraec — a new dry-coating process developed by the Fraunhofer Institute for Material and Beam Technology (IWS; Dresden, Germany; www.iws.fraunhofer.de) —…
'New food' GEA AG (Düsseldorf, Germany; www.gea.com) has received a contract from Novozymes A/S (Copenhagen, Denmark; www.novozymes.com) for a turnkey fitting of a major new plant to produce plant-based proteins for the plant-based food industry. The high double-digit million-euro order…
Biological processes can be used for the conversion of greenhouse gases into added-value chemicals. With a new, unique high-pressure (up to 10 bars) fermenter, the Flemish Institute for Technology Research (VITO; Mol, Belgium; www.vito.be) is researching how these processes can…
Construction is underway on a demonstration plant for manufacturing 1,5-pentanediol (1,5-PDO) from bio-based furfural, a platform chemical that can be derived from plant-based hemicellulose sugars. The process under construction by the company Pyran Inc. (Madison, Wis.; www.pyranco.com) offers a lower-cost…
A new fibrous catalyst-support material can enhance a wide range of industrial catalytic reactions, allowing higher yields and reduced coke buildup compared to pellet supports. Unifrax (Tonawanda, N.Y.; www.unifrax.com) leveraged its expertise in ceramic materials to develop the high-alumina fiber…
