Mitsubishi Chemical Corp. (MCC; Tokyo, Japan; www.m-kagaku.co.jp) has developed a new technology for producing 1,3-butadiene (butadiene) from waste butenes using a self-developed, proprietary catalyst. The process has been pilot tested (200-ton/yr capacity) at MCC’s Mizushima site in Japan, and the…
A less-expensive way of making the raw materials for carbon anodes (for aluminum smelting) and graphite electrodes (used to make steel in electric arc furnaces) has been developed by West Virginia University (UWV; Morgantown, W.Va.; www.wvu.edu). The conventional starting materials…
Milkweed, a plant that is toxic to farm animals and other creatures, may be a future source of a base material for sunscreen and other skin care products. Milkweed is harvested for floss, used as a hypoallergenic filler for pillows…
CSIRO Energy Technology (Newcastle, New South Wales, Australia; www.csiro.au) is developing a solar-powered air conditioning unit for residential use, using a desiccant-evaporative process to provide cool and dehumidified air. Thermally driven ab- or adsorption chillers are commonly used to provide…
A photocatalyst that is more active for decomposing volatile organic compounds (VOCs) with visible light than existing catalysts has been developed by researchers from the New Energy and Industrial Technology Development Organization (NEDO; Kawasaki City, Japan) in a project lead…
Last month, GE Oil & Gas (Florence, Italy; www.ge.com/oilandgas) received a contract to supply Eni S.p.A. (Rome; www.eni.it) with the largest refinery reactors of their type ever to be manufactured. GE Oil & Gas’ components-production facility in Massa, Italy, will…
Bioethanol Ethanol from plant and forestry waste and dedicated energy crops could replace approximately one-third of U.S. gasoline requirements by 2030 on a sustainable basis, according to a study by Sandia National Laboratories (Livermore, Calif.; www.sandia.gov) and General Motors Corp.…
For separating two components with similar volatilities, extractive distillation is typically used, whereby a high-boiling, non-volatile solvent is added to "break the azeotrope" — a process that is both energy intensive and often involves the use of hazardous solvents. In…
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…
