Scaleup is set for an air-separation membrane
The Electric Power Research Institute (EPRI, Palo Alto, Calif.; www.epri.com) has signed an agreement with Air Products (Allentown, Penn.; www.airproducts.com) to support the company’s development of a ceramic ion transport membrane (ITM) for air separation. The membrane is being tested…
A less-expensive way to make platinum catalysts
The cost of producing platinum catalysts could be reduced by up to 90% by a process being developed jointly by Lawrence Livermore National Laboratory (LLNL, Livermore, Calif.; www.llnl.gov) and Stanford University (Stanford, Calif.; www.stanford.edu). The process involves the deposition of…
Extracting drinking water from humidity
An energy-autonomous process for capturing air humidity for drinking water has been developed by scientists at the Fraunhofer Institute for Interfacial Engineering and Biotechnology (IGB; Stuttgart; www.fraunhofer.de) and Logos-Innovationen GmbH (Bodnegg, both Germany; www.logos-innovationen.com). The concept is suitable for supplying…
This photocatalyst works with visible light
A photocatalyst that uses visible light to deodorize and disinfect air has been developed by Hiroshi Taoda at the Materials Research Institute for Sustainable Development, National Institute of Advanced Industrial Science and Technology, Chubu, Nagoya, (AIST; Chubu, Nagoya, Japan; www.aist.go.jp).…
Another potential outlet for glycerin
Hiroshi Abe and colleagues at Biochemical Group of Research Institute for Innovation in Sustainable Chemistry, National Institute of Advanced Industrial Science and Technology (Tsukuba, Japan; www.aist.go.jp) have discovered a strain of acetic-acid bacteria (which normally oxidize ethanol into acetic acid)…
A new static mixer delivers substantial cost savings
At Achema last month (May 11–15; Frankfurt, Germany), Sulzer Chemtech AG (Winterthur, Switzerland; www.sulzerchemtech.com) launched a new static mixer, the SMX plus. For homogenizing viscous fluid, the new SMX plus has about half the pressure drop of the company’s standard…
