French researchers from the Institut Européen des Membranes (CNRS/ENSCM, Université Montpiellier; www.iemm.univ-mont2.fr) and the Institut de Chimie Radicalaire (CNRS, Aix-Marseille Université) have developed what is claimed to be the first dynamic membrane for water filtration that not only can adjust…
The Flexstream Gas Standards Generating System dynamically blends calibration gas standards for trace sulfur compounds in food-grade carbon dioxide. Specially designed permeation tubes add low-parts-per-billion (ppb) concentrations of typical sulfur species, including carbonyl sulfide, hydrogen sulfide and mercaptans, directly to…
It probably isn’t going to solve all the world’s energy needs, but producing biogas from waste can help slash the energy bills at some production plants, sewage-treatment plants and even farms. And for those companies offering biogas technology, business is…
There might be as many categories of catalysts as there are chemical processing applications. And, no matter what the specialty or application, most catalyst producers are in a constant state of research and development in order to meet the demands…
Technology originally developed for dewatering algae has shown success in separating hydrocarbons from produced water that results from oil and gas drilling. The method could be used in treating produced water for onsite re-use as hydraulic fracturing fluid. To harvest…
The research group of Masaru Ogura, an associate professor at the Institute of Industrial Science, University of Tokyo (www.u-tokyo.ac.jp), has clarified the degradation mechanism and the role potassium carbonate plays in the catalyst systems used for reducing soot from the…
Mitsubishi Heavy Industries, Ltd. (MHI; Tokyo, Japan; www.mhi.co.jp) will begin developing basic technologies for a triple combined-cycle power-generation system that integrates solid-oxide fuel cells (SOFC) and a gas turbine combined cycle (GTCC) power generation system. Under the umbrella of the…
Theres a growing trend toward generating electricity from biogas (see pp. 15–17), but roughly half of the total energy content of the fuel is released as heat, which is dissipated into the atmosphere unused. To improve the overall efficiency, researchers…
The research groups of professor Yasuyuki Tsuji and assistant professor Tetsuaki Fujihara at Kyoto University (Japan; www.ehcc.kyoto-u.ac.jp) have developed a copper-catalyzed reaction for synthesizing carboxylic acids, such as acrylic acid, using carbon dioxide as a raw material. The reaction involves…
A group of scientists from Fudan University (Shanghai, China; www.fudan.ac.cn) China, has reported what it claims to be the first example of artificial single-molecular water channels that can transport water across lipid membranes. Transmembrane water transport — through water channel…
