CO2-to-methanol
Researchers from Penn State University (State College, Pa.; www.psu.edu) and Dalian University of Technology (Dalian, China; www.dlut.edu.cn) have improved the CO2-to-methanol process by using a catalyst that combines copper and palladium. Using a palladium-to-copper atomic ratio range of 0.3 to…
Solvent-based process to recycle multilayered film
Later this year (Q4 2018), APK AG (Merseburg, Germany; www.apk-ag.de) will start up the first commercial plant to recycle multilayer packaging using the company’s solvent-based Newcycling process. The plant will process 8,000 metric tons per year (m.t./yr) of post-industrial multilayer…
Non-thermal treatment method for high-salinity produced water
A new pilot project brings together advanced membrane filtration with non-thermal, zero-liquid-discharge (ZLD) solvent exchange to efficiently treat high-salinity produced water from oil-and-gas operations. PetroH2O Recovery (Southlake, Tex.; www.petroh2o.com) is currently building a pilot plant with the capacity to process…
CNT-based photocatalysts enable solar water splitting
Splitting water with sunlight is a sustainable and environmentally friendly way to make hydrogen, but the conversion efficiency is presently very low, because current photocatalysts only work using ultraviolet radiation — a small fraction (3–5%) of sunlight. Now, a promising…
Australian minerals shipped to South Korea
Battery metals producer Australian Mines (Perth, Western Australia; www.australianmines.com.au) is scheduled to export the largest sample of battery-grade cobalt and nickel sulfate ever recorded from Australian mined and processed ore. The company will send 40 kg of nickel sulfate and…
Vacuum-aided membrane distillation results in ultra-pure water
At Achema 2018 (June 11–15; Frankfurt am Main, Germany), EvCon GmbH (Pliening-Landsham, Germany; www.evcon-water.com) showcased its new UPWater treatment system, which employs a patented vacuum multi-effect membrane distillation (VMEMD) technology to obtain ultra-pure water using less energy than comparable water-treatment…
Fuel-cell solution lowers operating costs using nanostructured catalysts
The two main barriers to widespread use of fuel cells have been securing a reliable source of hydrogen that avoids CO2 emissions, and cost — they have traditionally depended on expensive platinum and palladium catalyst materials. GenCell Energy Ltd. (Petach…
Advanced water electrolysis launched
Last month, thyssenkrupp Industrial Solutions AG (Dortmund, Germany; www.thyssenkrupp-industrial-solutions.com) launched industrial-scale water electrolysis systems that make large-scale hydrogen production from renewable electricity economically attractive. The advanced water electrolyzer (diagram) features a well-proven cell design paired with an especially large (2.7…
The commercial launch of 3-D-printed membranes
Last month, Nano Sun, a water technology start-up founded by a scientist from Nanyang Technological University (NTU; Singapore; www.ntu.edu.sg) launched a 3-D-printing facility to manufacture a new type of water-treatment membrane. Unlike conventional membrane-manufacturing processes, which use acids to make…
Chementator Briefs
TPA from PET bottles A chemical method previously developed for recovering monomers from polyester blend fabrics and textiles has now been adapted for use with waste plastic bottles made from polyethylene terephthalate (PET). The BCD Group (Cincinnati, Ohio; www.bcdinternational.com) developed…
