This patented process improves grease handling
Calcium-sulfonate complex greases are widely used in applications in the pulp-and-paper, marine and steel-manufacturing sectors. Within an ever-volatile lithium market, calcium-sulfonate greases are increasingly seen as a reliable alternative to lithium-based greases. However, typical methods for preparing high-performance calcium-sulfonate grease…
Reducing CO2 to formic acid
A research team led by Kenneth C. Neyerlin at the National Renewable Energy Laboratory (NREL; Golden, Colo.; www.nrel.gov), with members from Argonne National Laboratory (Lemont, Ill; www.anl.gov) and Oak Ridge National Laboratory (Tenn.; www.ornl.gov) has developed a membrane electrode assembly…
Chementator Briefs
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…
