Chementator: New ceramic-membrane system doubles rate and slashes cost for dehydrating ethanol
Hitachi Zosen Corp. (Hitz; Tokyo, Japan; edlinks.chemengonline.com/7369-531) is commercializing a new membrane for a hybrid-distillation system (HDS) that is especially suitable for dehydrating ethanol and isopropanol. The HDS can produce 99.7 vol.% ethanol from ethanol-water mixtures with 10 vol.% H2O…
Chementator: This platinum-free fuel cell runs on hydrazine
Daihatsu Motor Co., Ltd. (Osaka, Japan; edlinks.chemengonline.com/7369-532) has designed a fuel cell for powering automobiles, using nickel and cobalt for the electrodes (instead of conventional platinum and carbon), and hydrazine hydrate (N 2H4. H2O) as its fuel (instead of hydrogen).…
Chementator: Commercial production and debut of a new solid-acid catalyst for making biodiesel
Last month, Benefuel, Inc. (Mt. Prospect, Ill.; edlinks.chemengonline.com/7369-533) established an exclusive global agreement with Süd-Chemie India Pvt. Ltd. (SCIL; New Delhi) whereby SCIL will manufacture proprietary solid-acid catalysts for Benefuel’s biodiesel production facilities around the world. The patent-pending catalysts —…
Chementator: One less step to make activated carbon with dispersed metal nanoparticles
Nanostructured microporous carbons containing well-dispersed metal nanoparticles have the potential to improve the performance of fuel cells or catalysis. However, traditional techniques for embedding metal particles in porous carbons (post-synthesis treatment either by impregnation, adsorption, or ion exchange) can lead…
Chementator: New solid-state heat engine cycles H 2 through MEA like a fuel cell
Johnson ElectroMechanical Systems, Inc. (Atlanta, Ga.; edlinks.chemengonline.com/7369-536) in conjunction with professor Heshmat Aglan of Tuskegee University (Tuskegee, Ala.; edlinks.chemengonline.com/7369-537) has received a $75,000 grant from the U.S. Dept. of Energy (DOE; Washington, D.C.) to further develop the firm’s solid-state heat…
Chementator: Maintain pH, even at cyrogenic temperatures, with this buffer
Biotechnology samples, such as proteins, nucleic acids, biological specimens and pharmaceuticals, are typically stored frozen to extend their shelf life. However, a problem that has plagued researchers for decades is that the buffers used to maintain the pH of the…
Chementator: Sensor uses microfluidics to sniff for airborne contaminants
Airborne contaminants can be identified within 2 – 3 s with a new sensor developed by researchers at the University of California-Santa Barbara and Stanford University (Calif.). The researchers have founded a company, SpectraFluidics, Inc. (Santa Barbara; edlinks.chemengonline.com/7369-539) to commercialize…
Chementator: This CO2 -Recovery Process Set to Enhance EOR
Mitsubishi Heavy Industries, Ltd. (MHI; Tokyo, Japan; edlinks.chemengonline.com/7368-533) is marketing a new process that captures carbon dioxide from flue gas (FG) for enhanced oil recovery (EOR). The KM-CDR process uses a proprietary amine-based solvent (KS-1) in a packed column to…
Chementator: Using Living Plants to Synthesize Metallic Nanoparticles
Metallic nanoparticles are usually produced by wet chemical methods, often using toxic and flammable substances, or by physical methods such as evaporation and laser ablation. A group from the Laboratory for Sustainable Technology, School of Chemical and Biomolecular Engineering, at…
Chementator: This Solar Reactor Will Recycle Carbon Dioxide
A prototype solar reactor that will break carbon dioxide into carbon monoxide and oxygen, or split water into hydrogen and oxygen, will be started up this spring by researchers at Sandia National Laboratories (Albuquerque, N.M.; edlinks.chemengonline.com/7368-535). The ultimate goal of…
