Increased use of ethane from shale deposits as a feedstock for ethylene production has focused attention on the growing need for on-purpose production of butadiene, which has traditionally been produced primarily as a byproduct of conventional ethylene production from naphtha.…
Scientists from Yonsei University (Seoul, South Korea; www.yonsei.ac.kr) led by Prof Eunkyoung Kim, have developed a hybrid solar cell to enhance the photo-conversion efficiency of a solar cell with a thermoelectric device operated by photothermally generated heat. The efficiency was…
A dry adhesive technology inspired by the microscopic hairs on gecko’s feet is said to be the first of its kind to be commercialized. Known as Setex, the technology was developed by nanoGriptech Inc. (Pittsburgh, Pa.; www.nanogriptech.com), a company spun…
Alkylate — the main component in high-octane gasoline — is produced by catalytic reaction of C3–C5 olefins with isobutane in the presence of strong acid catalyst. Although there has been progress in the use of solid-acid catalysts (see, for example,…
A process that converts methane into hydrogen and carbon black has been developed by researchers at the Institute for Advanced Sustainability Studies (IASS; Potsdam; www.iass-potsdam.de) and the Karlsruhe Institute of Technology (KIT; Karlsruhe, both Germany; www.kit.edu). In a joint project…
A new desalination membrane has been developed by an industry-academia collaboration team, led by professor Toshinori Tsuru at Hiroshima University (Japan; http://home.hiroshima-u.ac.jp/membrane/en/index.html). The work is the culmination of a five-year project that began in 2011 with support from the Japan…
Ultrafiltration A new ultrafiltration fiber can increase permeability by 35% compared to previous generation fibers for wastewater treatment, according to developer Dow Water & Process Solutions (Midland, Mich.; www.dow.com). The XP Fiber was incorporated into the companys commercial UF modules,…
A new self-cleaning filter from Spiral Water Technologies Inc. (San Rafael, Calif.; www.spiralwater.com) can efficiently treat water with 25,000 mg/L total suspended solids (TSS). According to Spiral Water CEO Ashwin Gulati, the filters use much less energy — reportedly just…
A patented thermochemical regenerator system developed by Praxair, Inc. (Danbury, Conn.; www.praxair.com) has been demonstrated at its first industrial site, a glass-making facility in Mexico. The system, known as the Optimelt heat-recovery system, lowers fuel consumption in oxy-fuel furnaces, which…
Chemists at the University of Amsterdam (UvA; the Netherlands; www.uva.nl) have discovered a new catalytic method for removing cyanide ions from industrial wastewater. The heterogeneous catalyst — discovered jointly by Paula Oulego Blanco, Raveendran Shiju and professor Gadi Rothenberg from…
