A step closer to making CO by artificial photosynthesis
Researchers at Toshiba Corp. (Tokyo, Japan; www.toshiba.co.jp) have developed an artificial photosynthesis system that uses solar energy to convert CO2 and water into CO with 1.5% efficiency — the highest efficiency achieved to date. The company believes the technology has…
A highly efficient heterogeneous catalyst for making THF and other chemicals from biomass
The research group of Keiichi Tomishige at Tohoku University (Sendai, www.che.tohoku.ac.jp/~erec), in collaboration with Daicel Corp. (Tokyo, both Japan; www.daicel.com/en), has developed a catalytic reaction system that is highly efficient for synthesizing tetrahydrofuran (THF) — a widely used solvent and…
LED sight-glass light
Illumination is required for visual inspection of a process through a sight glass in a vessel or tank. A newly demonstrated light source, developed by L.J. Star Inc. (Twinsburg, Ohio; www.ljstar.com) and marketed as the LumiStar3000, is said to be…
Phase-change slurry
Researchers from the Fraunhofer Institute for Environmental, Safety and Energy Technology (Umsicht; Sulzbach-Rosenberg; www.umsicht.fraunhofer.de) and RWTH Aachen University (both Germany; www.rwth-aachen.de) have developed a new phase-change material (PCM) trade-named CryoSolPlus. The PCM is a dispersion of solid paraffin beads and…
Onsite CN generation
Gold mines using traditional cyanide-leaching extraction processes will benefit with the launch of a new technology allowing onsite production of sodium cyanide. The technology, developed by Synergen Met Pty Ltd (Brisbane, Australia; www.synergenmet.com), will eliminate a range of hazardous activities…
‘High-entropy’ alloy
Researchers from North Carolina State University (Raleigh; www.ncsu.edu) and Qatar University (Doha; www.qu.edu.qa) have developed a new metal alloy that is claimed to have a higher strength-to-weight ratio than any other existing metal material. The low-density, nanocrystalline alloy — Al20Li20Mg10Sc20Ti30…
New enzyme
Last month, Novozymes (Copenhagen, Denmark; www.novozymes.com) launched a new enzyme, dubbed Eversa, which is said to be the first commercially available enzymatic solution to make biodiesel fuels from waste oils. The enzymatic process converts used cooking oil or other lower-grade…
Polymer produced from CO2 waste gas makes commercial debut
For the first time, polypropylene carbonate (PPC) polyol, a versatile polymer made from CO2, is available at a commercial scale. Produced by Novomer Inc.’s (Waltham, Mass.; www.novomer.com) polymerization process, PPC polyol has been adopted into a formulation for polyurethane hot-melt…
CO2-capture project is largest to use calcium-looping technology
A cement plant in Taiwan has been retrofitted with the largest CO2-capture plant to use calcium-looping technology to date. The project, run by Taiwan’s Industrial Technology Research Institute (ITRI; Hsinchu, Taiwan; www.itri.org), demonstrates ITRI’s high-efficiency calcium-looping technology (Heclot) at a…
This new material repels oil and water
Meanwhile, a new class of highly fluorinated polymers is being developed at the Institute of Microstructure Technology (IMT), Karlsruhe Institute of Technology (KIT; Karlsruhe, Germany; www.kit.edu) that repels both water and oil. Last month, IMT was awarded €2.85 million funding…
