Amine-containing solids have been investigated as promising adsorbents for CO2 capture, but existing amine-containing adsorbents degrade by oxidation, making them unreliable for repeated CO2 adsorption-desorption cycles over a long period. The low stability requires the continuous addition of fresh adsorbents,…
Forward Osmosis Last month, Bioindustrial Innovation Canada (BIC; Sarnia, Ont.; www.bincanada.ca), Forward Water Technologies (FWT; www.forwardwater.com) and GreenCentre Canada (GCC; Kingston, Ont.; www.greencentrecanada.com) announced a private investment into FWT, supporting the commercial scaleup of a proprietary forward-osmosis technology. The initial…
A filter for water purification that can replace, with a single step, the complex, time-consuming and multi-stage processes currently needed, has been developed by a team from CSIRO Manufacturing (Sydney, Australia; www.csiro.au), led by Dong Han Seo. The team has…
C2H2 hydrogenation Last month, Clariant (Munich, Germany; www.clariant.com) launched OleMax 260, a new selective acetylene-hydrogenation catalyst, which is said to have extremely high ethylene selectivity and operational stability. Specially developed for ethylene producers with “front-end” process configurations, OleMax 260 offers…
One of the major obstacles to making hydrogen economically by splitting water is the high cost of noble-metal electrodes. Less expensive, non-noble metals only function as electrocatalysts under alkaline conditions, where the reaction requires more electricity. Now, professor Ryoichi Ito…
Researchers from the Chinese Academy of Sciences (Beijing, China; www.cas.cn), led by professor Ying-Jie Zhu, have reported a “smart” fire-alarm wallpaper prepared using ultralong hydroxyapatite nanowires and graphene oxide thermosensitive sensors. At room temperature, the graphene-oxide sensor is an electrical…
Using ultraviolet (UV) radiation or ozone (or both) to oxidize air pollutants, such as volatile organic compounds (VOCs) is a well-established treatment method in the chemical process industries (CPI). What is not so well known, however, is that for most…
Professor Toru Murayama at Tokyo Metropolitan University (Tokyo, Japan; www.haruta-masatake.ues.tmu.ac.jp), in collaboration with Chugoku Electric Power Co., Inc., has developed a vanadium oxide catalyst that removes oxides of nitrogen (NOx) from fluegas generated by the combustion of heavy fuel oil…
The world’s first pilot plant for manufacturing bio-based furan dicarboxylic methyl ester (FDME) began operating last month in Decatur, Ill. A collaboration between DuPont Industrial Biosciences (Wilmington, Del.; www.biosciences.dupont.com) and Archer Daniels Midland Co. (ADM; Chicago, Ill.; www.adm.com), the 60-ton/yr…
To meet strict sulfur specifications and reduce emissions, amine scrubbing and caustic treatment are frequently used to remove hydrogen sulfide from gas and liquid streams, but these methods are not effective for handling more complex organo-sulfur compounds, such as thiophenes…
