Chementator: Carbon-Capture Market
The global market for carbon-capture technologies was worth $88.7 billion in 2007, and is expected to increase to over $236.3 billion by 2012, according to a report published last month by BCC Research (Wellesley, Mass.; www.bccresearch.com). Postcombustion, the absorption of…
Chementator: EPA Delays GHG Action
On July 11, the U.S. Environmental Protection Agency (EPA; Washington, D.C.) released an Advanced Notice of Proposed Rulemaking (ANPR) soliciting public input on the effects of climate change and the potential ramifications of the Clean Air Act in relation to…
Chementator: PEEK Bioreactor Parts
The high salt concentrations, extreme pH values and high temperatures required in biotechnological research on extremophiles and marine organisms cause corrosion in the stainless-steel components of common fermenters. To enable further process development in these areas, Bioengineering AG (Wald, Switzerland;…
Chementator: Dow and NREL Join Forces in a Biomass Gasification Project
A thermochemical process for converting biomass to ethanol, other biofuels and chemical intermediates will be developed jointly by Dow Chemical Co. (Midland, Mich.; www.dow.com) and the U.S. Dept. of Energy’s National Renewable Energy Laboratory (NREL, Golden, Colo.; www.nrel.gov). Under the…
Chementator: Bio-Based Polyols
Last month, Cargill (Minneapolis, Min.; www.cargill.com) broke ground in Chicago on a $22-million manufacturing plant for producing BiOH polyols. Scheduled for startup in November, the facility will be the first world-scale biobased polyols plant; since BiOH polyols were commercialized in…
Chementator: Making Molten Glass ‘on-the-fly’ Can Cut Energy Consumption in Half
A process that makes glass by "zapping" the raw materials with a plasma as they fly through the air is being developed by Japanese researchers in a new project led by NEDO (New Energy & Industrial Technology Development Organization; Kawasaki,…
Chementator: Concentrating Light to Boost Solar-Energy Efficiency
Engineers at MIT (Cambridge, Mass.; www.mit.edu) are developing solar concentrators that have the potential to increase the electrical power output from solar cells by a factor of more than 40. Instead of actually focusing the light, as in systems being…
Chementator: A Well-known Phenomenon Finds a Commercial Application in a Gas Sensor
Optoacoustic gas detection determines gas content via the measurement of acoustic pressure waves that are propagated as a gas is irradiated under an appropriately tuned light. A gaseous-mixture sample passes through a membrane into a measurement cell, which contains an…
Chementator: An Improved Solar Process for Extracting H2 from Water
The production of hydrogen by water splitting promises to become less expensive through a solar-energy process being developed at Penn State University (University Park, Pa.; www.psu.edu). Like other photoelectrochemical methods, the process splits water into its two components, generating O2…
Chementator: Honors for Green Chemistry
Among this year’s award winners of the U.S. Environmental Protection Agency’s (EPA; Washington, D.C.) Presidential Green Chemistry Challenge are: Battelle, SiGNa Chemistry, Inc., Nalco Co., Dow AgroSciences and Michigan State University. Battelle (Columbus, Ohio; www.battelle.org) received the Greener Synthetic Pathways…
