Ligand-based separation method for rare earth elements
Rare-earth elements (REEs) are difficult to separate because of their similar properties, so conventional methods are often costly and generate significant amounts of waste. Researchers at Oak Ridge National Laboratory (ORNL; Oak Ridge, Tenn.; www.ornl.gov) have developed a new technique…
World’s largest double, re-slurry crystallization unit starts up in China
Last month, the world’s largest double re-slurry para-xylene crystallization unit was started as part of Shenghong Refining and Chemicals Co. Ltd.’s integrated refining/chemicals project in Lianyungang, Jiangsu Province, China. Double re-slurry crystallization takes advantage of freezing-point differences among the three…
Recovering proteins — and more — from rapeseed
Last month, a pilot plant officially opened at the Fraunhofer Center for Chemical-Biotechnological Processes (CBP; Leuna, Germany; www.cbp.fraunhofer.de). The plant aims to further develop a process that recovers multiple products from rapeseed, including high-grade, pre-raffinate-quality rapeseed oil, a high-grade, protein-rich…
Use existing refinery infrastructure for hydrogen storage and transport
Hydrogen is a clear piece of the decarbonization puzzle for many industrial sectors, including petroleum refining, but a major challenge lies in the storage and long-distance transport of hydrogen in its gaseous form. One proposed solution is the use of…
Onsite bioelectrochemical treatment for ultra-concentrated wastewater
The combination of electrochemical principles and microbial activity is the backbone of a treatment technology designed specifically for ultra-concentrated and challenging industrial wastewater. The Bioelectrochemical Treatment Technology (BETT) developed by Aquacycl (Escondido, Calif.; www.aquacycl.com) involves “microbial fuel-cells” that produce direct…
Chementator Briefs
Using Waste Heat To convert large amounts of waste heat into electricity as efficiently as possible, turbines with a high degree of efficiency are required that work with a special conversion process — the organic Rankine cycle (ORC). In a…
A hydrogen-fired furnace for ceramics
This month, a demonstration experiment will begin on a new firing furnace for ceramics that is being developed by NGK Insulators, Ltd. (NGK; www.ngk.co.jp). The furnace is fired with hydrogen instead of fossil fuels, thereby reducing CO2 emissions. H2-fired combustion…
These nonwovens are electrically conductive, but thermally insulating
Researchers at the University of Bayreuth (Germany; www.uni-bayreuth.de) have developed nonwoven materials that exhibit an unusual combination of high electrical conductivity and extremely low thermal conductivity. These composites of carbon and silicon-based ceramic can be manufactured and processed cost-effectively by…
Scaleup for a hydro-organic-metallurgical process
Following a successful proof-of-concept to recycle spent lithium-ion batteries (LIBs) using reagent extracted from fruit peel waste, Nanyang Technological University, Singapore (NTU; www.ntu.edu.sg) has partnered with Se-cure Waste Management Pte. Ltd. (SWM; Singapore; www.se-curewaste.com) to scale up the technology in…
Converting algae shells into ‘tunable’ perovskites
A research team, led by scientists at the Center for Molecular Bioengineering (B CUBE) at the Technical University of Dresden (Germany; www.tu-dresden.de), has converted mineral shells of single-celled algae into lead-halide perovskites with tunable physical properties. The new perovskites have…
