Using a workhorse technology known as the gas-subcooled process (GSP), most natural gas plants recover between 85 and 90% of ethane in raw natural gas streams. Honeywell UOP (Des Plaines, Ill.; www.uop.com) has developed a modular retrofit unit designed to…
Active surfactants are those that are responsive to an external stimulus, such as temperature, light, electric or magnetic fields or chemical agents. Scientists from the Institute for Basic Science (Daejeon, South Korea; www.ibs.re.kr) have developed surfactants based on functionalized nanoparticle…
It has been a challenge to find materials that can reliably detect volatile organic compounds (VOCs) and toxic gases in air at the parts-per-billion (ppb) level, or that can be used for therapeutic diagnosis from breath analysis. That’s because two…
Waste to chemicals A consortium of companies, including Air Liquide (Paris, France; www.airliquide.com), AkzoNobel Specialty Chemicals (Amsterdam, the Netherlands; www.akzonobel.com), Enerkem Inc. (Montreal, Canada; www.enerkem.com) and the Port of Rotterdam, has signed a project development agreement covering initial investments in…
Lithium-ion batteries based on intercalation compound electrodes exhibit poor performance at temperatures below 0°C. Insufficient ionic conductivity and freezing of the electrolyte are generally seen as the main reasons for the poor performance of rechargeable batteries at low temperatures. Although…
A group of Japanese researchers have developed a photocatalytic panel reactor with large area (1 m2) that splits water into H2 and O2 using only natural sunlight. The NEDO (www.nedo.go.jp)-supported project — which includes partners Japan Technological Research Association of…
Acrylonitrile (ACN) — a precursor in nearly all carbon fibers — is typically produced from propylene and ammonia, but a new method uses biomass-derived second-generation sugars. The process was developed by Southern Research (Durham, N.C.; www.southernresearch.org) and seeks to provide…
A team from Ulsan National Institute of Science and Technology (Ulsan, South Korea; www.unist.ac.kr), led by professor Jong-Beom Baek has introduced a synthetic methodology for fabricating a three-dimensional porous organic network with a high specific surface area via a solid-state…
New membranes developed at Tufts University (Medford, Mass.; www.tufts.edu) can effectively separate similar chemicals based on not only size but on electrostatic charge. “Currently, there are no commercial membranes that are designed to separate organic molecules of similar size but…
Using a simple, ligand-free palladium catalyst system, researchers at McGill University (Montreal, Que., Canada; www.mcgill.ca) have demonstrated that metal carbonylation — a core chemical reaction for many industrial products — can be used to synthesize ketones directly from hydrocarbons. The…
