Aerzen Maschinenfabrik GmbH (Aerzen, Germany; www.aerzen.com) has commercialized the first rotary lobe compressor, the Delta Hybrid, which combines the technologies of both a rotary lobe blower and a screw compressor. This union reduces the energy consumption by up to 15%…
A microreactor system for producing hydrogen peroxide from H2 and O2 has been developed by Sohei Matsumoto and Tomoya Inoue at the Research Center for Ubiquitous MEMS and Micro Engineering, National Institute of Advanced Industrial Science and Technology (AIST; Tsukuba,…
In order to shift the country’s energy base from petroleum, the Indonesian government has implemented a policy aimed at shifting to coal. Because low-rank coal (LRC) accounts for about 80% of the nation’s coal resources, effective utilization of these reserves…
Standardized steam-methane-reforming (SMR) reactor units recently commercialized by Air Liquide (Paris, France; www.airliquide.com) allow direct hydrogen production at customer sites at costs much lower than those associated with alternative H2 supply modes, including electrolysis and transporting compressed or liquefied H2.…
A group of Singapore researchers have reported a new approach to induce the coiling of prefabricated gold nanowires (AuNWs) inside polymer shells, leading to structures resembling torsion springs. In contrast to gas-phase methods that require high temperatures and are limited…
Photos: Teijin Group Toho Tenax Co. (Tokyo; www.tohotenax.com), the main company of the Teijin Group’s carbon fibers business, has commercialized a gas-diffusion layer (GDL) made of carbon fiber fabric for use as an electrode component for fuel cells. GDLs are…
A plasma-based process has achieved a 30% yield of methanol from methane in a microreactor system developed by a research team led by Tomohiro Nozaki, associate professor at Tokyo Institute of Technology (TiTech; Tokyo, www.mech.titech.ac.jp). The yield is nearly the…
Westec Environmental Solutions, LLC (WES; Chicago, Ill.; www.wes-worldwide.com) has developed a gas-liquid absorption technology that can dramatically enhance mass transfer in gas-liquid absorption, extraction and scrubbing systems. The patented WES Absorber operates co-currently and creates a micro-froth matrix that intensifies…
Enerkem Inc. (Montreal, Can-ada; www.enerkem.com) has broken ground in Edmonton, Alberta, on what is said to be the world’s first industrial-scale plant to produce liquid fuel from municipal solid waste. When the plant starts up at the end of 2011,…
Plastic derived from corn, used mostly for bottles and cups, costs about 20% more than petroleum-based plastics, but has two desirable qualities: it comes from a renewable resource and is biodegradable. However, the use of the plastic — polylactic acid…
