The Industrial Technology Research Institute of Taiwan (ITRI, www.itri.org.tw) is conducting a 10-m3/d pilot-plant project to test the performance of its A2O membrane system for municipal wastewater treatment. The project, which is nearing completion, has already supplied important data, including capital…
This Fall, Vantec Co. (Tochigi Prefecture, Japan; www.vantec-jp.com) plans to commercialize a water electrolyzer that incorporates electrodes with a ten-year lifetime — nearly twice that of conventional technology, says the manufacturer. The long-lasting electrodes are expected to reduce the cost…
Nippon Steel Corp. (Tokyo; www.nsc.co.jp) and Kobe Steel, Ltd. (Kobe, Japan; www.kobelco.com) plan to begin construction of a plant to recycle steel-mill dust — a byproduct from the steelmaking process — into direct reduced iron (DRI). The two companies will…
Professor Keiichi Tomishige and colleagues at Tohoku University (Sendai City, Japan; www.che.tohoku.ac.jp/~erec/) have developed a high-performance catalyst for synthesizing 1,3-propanediol (PDO) — a raw material for highly functional poly(trimethyleneteraphthalate) (PPT) fibers — from glycerin as starting material. The catalyst —…
Liquid copper is employed to gasify wastes in a process being developed by Ze-gen (Boston, Mass.; www.ze-gen.com) and will be tested in a small commercial plant in an industrial park in Attleboro, Mass. Scheduled for completion late next year, the…
Last month, RWE Power (Cologne, Germany; www.rwe.com) and Linde-KCA-Dresden GmbH (www.linde-kca.com), a subsidiary of The Linde Group (Munich, Germany; www.linde.com), signed a framework agreement on the use of RWE’s WTA technology — a German acronym for fluidized-bed (FB) drying with internal…
A novel catalyst designed by scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley, Calif.; www.lbl.gov) and the University of California at Berkeley (www.berkeley.edu) has shown the ability to catalyze the electrolysis of water into hydrogen and…
New technology for fabricating nanoscale polymer threads boosts yields and improves control compared to conventional methods for producing nanoscale fibers by using a technique analogous to that for making cotton candy. The technology, known as rotary jet spinning (RJS), was…
Carbon nanotube (CNT) membranes developed by researchers at Rice University (Houston; www.rice.edu) could have applications as nanoparticulate filters, and as nanoscale scaffolds for catalysts. The devices are silicon dioxide wafers with laser-bored holes (~500-µm dia.). The holed wafers are subjected…
Kazuhiro Sayama and colleagues at the Solar Light Energy Conversion Group at Energy Technology Research Institute, National Institute of Advanced Industrial Science and Technology (AIST; Tsukuba, Japan; unit.aist.go.jp/energy), have developed a cesium-treated tungsten oxide photocatalyst that shows a 19% quantum…
