Ultrasound has been applied, with limited success, for the remediation of contaminated soil. Up to now, the approach has been to first extract the contaminant from the soil into a liquid, which is then passed through a sono-reactor where the…
In a so-called thermoacoustic engine, researchers from the Energy Research Center of the Netherlands (ECN; Petten, Netherlands; www.ecn.nl) have achieved a record efficiency in the conversion of heat to sound, improving the existing record of 41% to 48% of the…
In late 2009, Microbia PE, Inc. (Lexington, Mass.; www.microbia-pe.com) will begin commercialization of its initial carotenoid products. Microbia plans to produce β-carotene, astaxanthin, zeaxanthin, cathaxanthin and lutein — all five carotenoid products that currently have significant commercial value. These carotenoids…
A new bioplastic Up to now, the main plastic produced from renewable resources has been polylactic acid (PLA), which is derived from corn starch. However, because PLA does not have the same level of performance as petroleum-derived plastics, PLA has…
Last month, Uralchem OJSC (Moscow, Russia; www.uralchem.com) started production of a new fertilizer, called ASN 32:0:0:5, at Kirov-Chepetsk Chemical Works, OSJ. Granules of the new ASN formulation have a gradient structure with a high concentration of ammonium sulfate on the…
New MMA process Last month, the world’s first plant to produce methyl methacrylate (MMA) using the Alpha process of Lucite International Group Ltd., (Southampton, UK; www.lucite.com) started up. The 120,000-m.t./yr (metric ton per year) plant is located on Jurong Island…
Tantaline (Lyngby, Demnark; www.tantaline.com) has developed a process that creates a surface alloy of tantalum on a metal substrate (typically stainless steel). As a result, the surface acquires the corrosion resistance of tantalum — the most corrosion resistant metal commercially available…
Heavy crude UOP LLC (Des Plaines, Ill.; www.uop.com) plans to do further development of its Catalytic Crude Upgrading (CCU) technology through an agreement with Brazil’s Petrobras (Rio de Janeiro) and Albemarle Corp. (Baton Rouge, La.). CCU is a process…
Last month, Lanxess AG (Leverkusen, Germany; www.lanxess.com) launched Levotan X-Cel, an polymer mixture based on expandable microcapsules, for retannage in leather processing. With a diameter of 5 – 20 µm, the microcapsules are small enough to penetrate into the collagen…
A method for identifying less-expensive catalysts, compared to commercial, precious-metal-based ones, is starting to deliver results by researchers at the Center for Atomic-scale Materials Design, Dept. of Physics, Technical University of Denmark (CAMD; Lyngby; www.camd.dtu.dk) and their collaborators. The computer-aided…
