This process realizes large costs savings for manufacturing silicon wafers
Crystal Solar Inc. (Santa Clara, Calif.; www.xstalsolar.com) is preparing for high-volume production of silicon wafers using a process that forms the wafers directly from trichlorosilane (TCS) gas using a chemical vapor deposition (CVD) epitaxy process that can significantly lower the…
Demonstration plants for biomass-to-sugar technology under construction
Edeniq Inc. (Visalia, Calif.; www.edeniq.com) announced progress in building demonstration facilities in Brazil and China that feature the company’s proprietary process for converting cellulosic biomass into industrial sugar for fermentation or catalytic conversion (diagram). In Brazil’s São Paulo state, Edeniq…
September Chementator Briefs
CO2-to-syngas . . . Scientists from the University of Illinois at Chicago ( www.uic.edu) have developed a catalytic system — molybdenum disulfide and an ionic liquid — to convert CO2 into synthesis gas, (syngas; a mixture of CO and…
An inexpensive, sensitive device for detecting explosives
A microfluidic, paper-based analytical device (µPAD) — in conjunction with confirmation by a “lab-on-a-chip” analysis — was developed for detection of three explosives (trinitro aromatics) by a team from the University of Technology Sydney (Sydney, Australia; www.uts.edu.au), the University of…
This portable device measures Hg+2 in water samples
An ultra-sensitive, low-cost and portable system for detecting mercury in water has been developed by University of Adelaide (Australia; www.adelaide.edu.au) researchers, in collaboration with the Universitat Rovira i Virgili (Tarragona, Catalonia, Spain; www.urv.cat). Project leader Abel Santos, of the Adelaide’s…
Commercial debut planned for an FCC process with enhanced olefins production
JX Nippon Oil & Energy Corp. (JX_NOE; Tokyo, Japan; www.noe.jx-group.co.jp) plans to construct the first commercial plant to utilize its high-severity fluid catalytic cracking (HS-FCC) technology, which has been demonstrated to generate higher ethylene and propylene yields compared to conventional…
A more direct route to ethyl acetate
Last June, Showa Denko K.K. (SDK; Tokyo, Japan; www.sdk.co.jp) started commercial operation of its new 100,000-ton/yr ethyl acetate plant at Oita Complex. The new plant is the first commercial facility in Japan to use the company’s proprietary production-process technology. The…
Microporous vanadosilicate efficiently removes cesium from wastewater
The effective removal of Cs+ ions from contaminated groundwater, seawater, and radioactive nuclear waste is crucial for public health and for the operation of nuclear power plants. Although several methods for the removal of Cs+ ions have been developed, there…
This production process cuts Pt usage in catalytic converters in half
Chemists from the National Institute of Advanced Industrial Science and technology (AIST; Tsukuba City, Japan; www.aist.go.jp) have developed a procedure for making the catalysts used in catalytic converters for treating the exhaust from diesel engines. The process, developed with support…
Demonstration of methane fermentation to lactic acid
What is said to be the world’s first fermentation pathway from methane to lactic acid has been demonstrated by Calysta, Inc. (Menlo Park, Calif.; www.calysta.com). The fermentation process begins with an organism that feeds off of methane rather than typical…
