Research groups at Keio University (Hiyoshi; www.bio.keio.ac.jp/labs/kmiyamoto) and Kyoto Institute of Technology, in collaboration with Teijin Ltd. and Adeka Corp., have discovered a bacterium that can degrade and assimilate poly(ethylene terephthalate) (PET), and have clarified the decomposition mechanism. This is…
Fe-free HTS catalyst Last month at the Nitrogen + Syngas 2016 conference (Berlin, Germany; February 29–March 3), Haldor Topsøe A/S (Lyngby, Denmark; www.topsoe.com) introduced SK-501 Flex, a new high-temperature shift (HTS) catalyst with the unique ability to operate at any…
A scalable technology for allowing the cost-effective manufacture of superhydrophobic metallic coatings has been demonstrated in the laboratory. The method could have applications for heat exchangers, condensers, high-temperature and high-conductivity applications and other types of equipment. The startup company Maxterial…
Vigorous microbial growth in bioreactors raises cell density, which is a source of heat stress and can hinder production efficiency. To address the issue, scientists have tried introducing genes for heat-shock proteins (HSPs) into workhorse industrial bacteria like Escherichia coli,…
Light olefins, such as ethylene and propylene, are primarily made by the catalytic cracking of crude oil. Alternatively, two other methods were developed during the time of high oil prices, both of which convert synthesis gas (syngas) to olefins: the…
The first commercial-scale, natural-gas-fermentation facility in the U.S. will break ground by the end of 2016, according to Alan Shaw, CEO of Calysta Inc. (Menlo Park, Calif.; www.calysta.com). In a collaboration with agricultural giant Cargill Inc. (Minneapolis, Minn.; www.cargill.com), Calysta…
Sydney University’s Laboratory for Sustainable Technology (Sydney, Australia; www.sydney.edu.au) and the technology-commercialization-firm Hazer Group (Perth, Australia; www.hazergroup.com.au) are collaborating to scale up the Hazer Process, which uses an iron-ore catalyst to produce hydrogen and graphite from natural gas. Natural gas…
A multi-company partnership has achieved the largest-ever use of molybdenum/tungsten (Schrock-type) catalysts for a metathesis process involving ethylene and renewable oils. The reaction run, which produced primarily 1-decene and 9-decenoic acid methyl ester from ethylene and plant oils, represented a…
Milliken & Co. (Spartanburg, S.C.; www. millikenchemical.com) has optimized its core clarifying technology for polypropylene (PP) resin to raise the clarity level to compete with that of polyethylene terephthalate (PET), polystyrene (PS) and polycarbonate (PC). The optimized technology allows the…
Conventional catalytic converters in automobiles are based on heterogeneous catalyst systems with precious metals (such as Pt and Pd), rare earth elements and Ce (in the form of CeO2). However, the cost and limited resources of such metals is driving…
