Lime Injection Engineers at the Institute for Technologies of Metals (ITM) at the University of Duisburg-Essen (Duisburg, Germany; www.uni-due.de), together with Fritz Winter Eisengießerei GmbH & Co. KG (FW; Stadtallendorf; Germany) and the FEhS – Building Materials Institute e.V. (Duisburg)…
A closed-loop hydrometallurgical process for low-carbon iron processing
Electrification will be a key factor in decarbonizing hard-to-abate sectors, but challenges arise in applications that require very high temperatures, such as steel production. The intense heat requirements for converting iron ore into metal contribute significantly to the CO2 emissions…
A fungus converts cellulose directly into a platform chemical
Conventional bioprocesses use three separate steps to convert cellulose into products, such as bioplastics and biofuels. The consolidated bioprocess (CBP) combines all steps — cellulase production, cellulose hydrolysis and product fermentation — in a single reactor. Using the natural abilities…
CO2-to-methanol conversion improved with catalyst-support ion swap
Researchers at Oak Ridge National Laboratory (ORNL; Oak Ridge, Tenn.; www.ornl.gov) and a team of interdisciplinary scientists tripled the yield of methanol in the catalytic hydrogenation reaction of carbon dioxide by introducing hydrides into the catalyst support material. The researchers…
Functionalized ionic liquids enhance L-L extraction of Ga and Ge
Gallium and germanium are considered critical materials due to their multiple uses in semiconductors, optics, healthcare and pharmaceuticals, and other high-technology applications. Current solvent-based extraction methods for recovering these elements suffer from significant drawbacks, such as low separation efficiency, poor…
Making cement with 70% lower CO2 emissions
A process commercialized by Fortera Corp. (San Jose, Calif.; www.forteraglobal.com) creates a cement product that reduces CO2 emissions by 70% on a ton-for-ton basis, and can be blended with conventional cement or used as a standalone material to make ready-mix…
Chementator Briefs
E-Cracking Last April, BASF SE (Ludwigshafen, Germany; www.basf.com), SABIC (Riyadh, Saudi Arabia; www.sabic.com) and Linde Engineering (Pullach, Germany; www.linde-engineering.com) inaugurated the world’s first demonstration plant for large-scale electrically heated steam-cracking furnaces. Following three years of development, engineering, and construction work,…
New microreactors and flow loops improve asphaltene management
Asphaltenes are an ultra-complex fraction of crude petroleum that comprise a diverse population of molecules that vary in size, solubilities, aggregation states and hetero-atom contents. Asphaltene buildup and deposits create many operational and safety issues, and can occur anywhere in…
On-demand electric heat can reach near-flame temperatures
Electrification provides an avenue for industrial decarbonization, but many electric-heating options cannot handle the high temperatures and scale required for industrial use. Electrified Thermal Solutions (ETS; Medford, Mass.; www.electrifiedthermal.com) has taken a new approach to industrial heating through its JouleHive…
Isotope-enrichment process starts commercial production
Traditional isotope enrichment to separate radioactive atoms is highly capital intensive, and the supply chains for the materials are constrained, with the majority of enriching capability located in Russia. In a bid to expand isotope availability and lower costs, ASP…
