A liquid metal membrane with liquid gallium (Ga) sandwiched between two porous silicon carbide supports offers a pathway to improve the currently available membranes of solid palladium (Pd) metal for separating hydrogen after the steam reforming of methane. Pd metal…
In critical pumping applications involving toxic or expensive products, the use of double mechanical seals or external flushing fluids can lead to product contamination or leakage, as well as additional costs for installation and monitoring. Although hermetically-sealed pumps, such as…
DPC monomer As part of an NEDO project, Asahi Kasei Corp. (Tokyo, Japan; www.asahi-kasei.co.jp) verified a newly developed process for diphenyl carbonate (DPC), a monomer used to produce polycarbonate (PC) at its Mizushima Works (Kurashiki, Okayama). The stability and operability…
Lithium Australia NL (Perth, Western Australia; lithium-au.com) has generated 99.8% (battery-grade) lithium carbonate from lithium-bearing silicates, such as spodumene, using its Sileach process — a hydrometallurgical process that does not require an energy-intensive roasting step. The company says Sileach has…
Graphene can be produced and isolated by exfoliating graphite, but existing processes are difficult and expensive. The most common method involves aggressive oxidation of graphite and results in diminished properties and added expense. Another approach — mechanical exfoliation — requires…
A new research partnership between the Water Environment & Reuse Foundation (WERF; Alexandria, Va.; www.werf.org) and the University of Texas at Arlington (UTA; www.uta.edu) seeks to tackle one of the most challenging and persistent water contaminants — perfluorooctane sulfonate (PFOS).…
JFE Steel Corp. (Tokyo, Japan; www.jfe-steel.co.jp) plans to build a pilot plant for using ferro coke in the ironmaking process at its Fukuyama area of West Japan Works, with support from the New Energy and Industrial Technology Development Organization (NEDO;…
Last month, Mitsubishi Hitachi Power Systems, Ltd. (MHPS; Yokohama, Japan; www.mhps.com) launched a new, pressurized, hybrid power-generation system (photo) that integrates solid-oxide fuel cell (SOFC) stacks with micro gas turbines (MGT). The hybrid system (diagram) has a broad range of…
A major challenge in using hydrogen to power motor vehicles is the difficulty in transporting H2 to refueling stations. Researchers at CSIRO Energy (Melbourne, Australia; www.csiro.au/energy) have responded to the challenge by converting H2 to NH3 and then using existing…
VanadiumCorp Resource Inc. (Vancouver, B.C., Canada; www.vanadiumcorp.com) has achieved direct and consistent recovery of vanadium electrolyte, vanadium oxides and titanium from vanadiferous titanomagnetite (VTM; vanadium-rich Fe3–xTixO4) using hydroelectricity, from the company’s Lac Dore Vanadium Project in Quebec. The company has…
