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…
Graphene Laboratories Inc. (Reading, Mass.; www.graphenelab.com) and CVD Equipment Corp. (Ronkonkoma, N.Y.; www.cvdequipment.com) recently announced the commercial launch of single-layer graphene films, marketed as CVDGraphene, grown by a chemical vapor deposition (CVD) process. Using slightly modified CVD equipment that has…
Last month at the IFAT Entsorga trade fair (September 13–17; Munich, Germany), Süd-Chemie AG (Munich; www.sud-chemie.com) introduced a chemical-free process that increases the energy production of wastewater-purification and biogas plants by as much as 30% while significantly reducing the disposal…
Improved C5 use Some 106,000 ton/yr of so-called spent C5 fraction is generated at Mitsui Chemicals Inc.’s (Mitsui; Tokyo, Japan; www.mitsuichem.com) naphtha cracker at its Chiba Factory. Presently, the company is selling about half of the C5 fraction (50,000 ton/yr)…
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…
Codexis (Redwood City, Calif.; www.codexis.com) and CO2 Solution (Quebec City, Canada; www.co2solution.com) have jointly developed a cost-effective method for capturing carbon dioxide from coal-fired power plants. Solvent-based systems for capturing CO2 are relatively well-understood, but they have not been widely…
