Current oil-water separation technologies, such as centrifugation, filtration, dissolved air flotation, distillation, oil skinners, adsorption and electrochemical methods, are of low efficiency and consume a lot of energy during complex separation processes. Mesh membranes have attracted much interest lately, and…
In order for ammonia to serve as a hydrogen carrier, it is necessary to develop separation techniques that can reliably recover H2 from the decomposition of NH3 with sufficient purity for operating proton-exchange membrane (PEM) fuel cells. A step in…
Aerogels — ultralight, insulating and heat-resistant nanoporous solids — offer benefits in many applications, but commercially available aerogels are typically limited to just two formats: particles and blankets. Aerogel Technologies, LLC (Boston, Mass.; www.aerogeltechnologies.com) is currently constructing a pilot plant…
A collaboration between JGC Corp. (JGC, Yokohama, Japan; www.jgc.com), the National Institute of Advanced Industrial Science and Technology (AIST), the National Institute of Technology, Numazu College, and JGC’s subsidiary, JGC Catalysts & Chemicals Ltd., (JGC Group), under the auspices of…
A new production process for engineering a range of nano- and microstructured solid materials can reduce the costs of manufacturing the materials compared to conventional “wet-chemistry” approaches, and can allow novel chemistries that are not accessible through traditional methods. Developer…
The research group of Yabing Qi at Okinawa Institute of Science and Technology (OIST; Japan; https://groups.oist.jp/emssu), in collaboration with Shengzhong Liu at Shaanxi Normal University, China, has developed a simple method to fabricate thin (1µm) perovskite films that can be…
Shu Kobayashi and colleagues at the University of Tokyo (Japan; www.chem.s.u-tokyo.ac.jp) reported on two new catalysts for synthesizing fine chemicals using their continuous-flow reactor system. The first technology is a novel methodology using CsF.Al2O3 as a highly efficient, environmentally benign,…
O2 recycling A beta field trial has been successfully completed for an adsorption-based technology designed to separate unreacted oxygen in ozone-generating systems. The technology, known as Ozora, was developed by Linde LLC (Bridgewater, N.J.; www.lindeus.com), and was originally launched last…
A project has been announced to demonstrate Microvi’s (Hayward, Calif.; www.microvi.com) pollutant-removal-and-recovery technology for phosphorus in water. The objective of the demonstration is to reduce total phosphorus levels to 0.1 mg/L at a wastewater treatment plant. The nine-month project is…
A chemical vapor deposition (CVD) process that bonds a silicon-oxide film to metal surfaces of any shape is being scaled up by Wicoatec GmbH (Ulm, Germany; www.wicoatec.com). Serial production started in 2017 with pilot-scale equipment, and capacities will be tripled…
