A new catalyst enables lower-temperature H2 production using the sulfur-iodine cycle
Among the many different ways being investigated for making hydrogen “from water” is the so-called sulfur-iodine (S-I) cycle, which involves three chemical reactions whose net products are H2 and O2: the decomposition of sulfuric acid into SO2, H2O and O2;…
Quick-charging lithium ion batteries on the horizon
Conventional lithium-ion batteries (LIBs) are unsuitable for high power applications as in electric vehicles, because they take a long time to charge, according to a team from the Interdisciplinary School of Green Energy, of the Ulsan National Institute of Science…
Odor control in small doses
A team headed by professor Zhiguo Yuan, from the Advanced Water Management Center, University of Queensland (Brisbane, Australia; www.awmc.uq.edu.au) claims to have developed a new method for corrosion and odor control in sewers that is more cost-effective and environmentally friendly…
October Chementator Briefs
Flexible aerogels Researchers at the NASA Glenn Research Center (Cleveland, Ohio; www.nasa.gov) have developed new flexible aerogels that could eventually be used in highly insulating materials and linings. Aerogels, sometimes called “solid smoke,” are superlightweight structures of silica reinforced…
A cryogenic turbo mill generates rubber powder from recycled tires
A process developed by Lehigh Technologies (Lehigh; Tucker, Ga.; www.lehightechnologies.com) for embrittling and milling rubber from end-of-life vehicle-tire material is capable of generating micron-scale rubber particles that can be used in a host of rubber, foam and plastic products to…
A concept for making gasoline from air
Air Fuel Synthesis Ltd. (AFS; Darlington, U.K.; www.airfuelsynthesis.com) has recently demonstrated a process for producing carbon-neutral liquid hydrocarbon (HC) fuel from air-captured carbon dioxide and hydrogen. The proof-of-concept demonstration facility, located at Teesside, England produces 5–10 L/d of liquid HCs.…
Progress for making smart membranes
Last month marked the completion of the three-year, €3.6-million E.U.-funded research project, Self-assembled Polymer Membranes (SelfMem). Coordinated by the Institute of Polymer Research at the Helmholtz-Zentrum Geesthacht (HZG; Germany; www.hzg.de), with twelve partners from industry and academia in Israel, Canada…
New catalysts for Baeyer-Villiger oxidation reactions
Kazuaki Ishihara and his group at Nagoya University (Japan; www.ishihara-lab.net) have established a new, environment friendly reaction technology — using Baeyer-Villiger oxidations — for selectively oxidizing ketones into esters. The reaction uses hydrogen peroxide as the oxidant, and has potential…
A little gold can reduce the Pt loading in fuel cells
A challenge in the development of polymer-electrolyte membrane fuel cells is the durability and electrocatalytic activity of platinum-based electrocatalysts. The sluggishness of the oxygen reduction reaction (ORR) causes the fuel cell performance to be limited by the cathodic reaction, and…
Save energy (and more) with this hybrid compressor system for EOR
Last month, Lewa GmbH (Leonberg, Germany; www.lewa.de) and Burckhardt Compression AG (Winterthur, Switzerland; www.burckhardtcompression.com) signed an agreement to commercialize hybrid compression systems for enhanced-oil-recovery (EOR) applications. EOR — injecting high-pressure CO2 into oil wells to both reduce the crude oil’s…
