Last month, Pittsburgh Iron Oxides, LLC (Pirox; New Brighton, Pa.; www.piroxllc.com) was granted U.S. patent No. 7,744,848 for its process of producing high-purity magnetite (Fe3O4). The company produces synthetic magnetite, tradenamed SuperMagnetite, which has greater than 99% purity and exhibits…
Flyanic LLC (Newark, N.J.; www.flyanic.com) has developed an industrial-scale and economical process for grinding cement, flyash and other cementitious materials to a median particle size of 1 micron, making them suitable for use in concrete and mortar. For example, flyash…
The research group of Kazuo Tajima at Kanagawa University (Yokohama, Japan; apchem2.kanagawa-u.ac.jp) have developed a new emulsification process that enables biodiesel fuels (BDFs) to be used without any purification process, thereby reducing production costs by one fourth. Tajima estimates that…
Researchers at the Fraunhofer Institute for Mechanics of Materials (IWM; Halle, Germany; www.fraunhofer.de) have developed ceramic membranes with uniform pore structure and tight pore-size distribution, which makes them more stable and delivers considerably higher flowrates than existing ceramic membranes, which…
Strata Technology Ltd. (Sunbury-on-Thames, U.K.; www.stratatec.co.uk) has commercialized the Cambridge Multipass Rheometer (MPR), which was developed by professor Malcolm Mackley at the Dept. of Chemical Engineering and Biotechnology, Cambridge University (www.ceb.cam.ac.uk) for advanced studies of the rheological properties of melts,…
ADA-ES, Inc. (Littleton, Colo.; www.adaes.com) and Arch Coal, Inc. (St. Louis, Mo.), the U.S.’s second-largest coal producer, have signed an exclusive development and licensing agreement for an ADA-ES process that reduces mercury emissions from coal-fired plants by pretreating the coal.…
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…
