A renewable precursor for the polyurethane industry
For the first time, polyols derived only from castor oil can be used to produce tough coatings, flexible adhesives, soft sealants and elastomers. The Polycin GR Series is the latest polyol line from Vertellus Performance Materials Inc. (Indianapolis, Ind.; edlinks.chemengonline.com/6519-543).…
Cellulosic bioethanol
Mascoma Corp. (Cambridge, Mass.; edlinks.chemengonline.com/6519-547) has raised $30 million in its second round of Venture funding — led by General Catalyst Partners (Cambridge, Mass.) — to further develop a new way to make bioethanol from cellulose. Mascoma aims to reduce…
FG treatment
American Municipal Power-Ohio (AMP-Ohio; Columbus) plans to use the emissions-control technology of Powerspan Corp. (Portsmouth, N.H.; edlinks.chemengonline.com/6519-550) on the proposed AMO Generating Station Project. The project — a 1,000 MW pulverized-coal power plant — is under development near the Ohio…
Purifying refinery gas
BASF AG (Ludwigshafen, Germany; edlinks.chemengonline.com/6519-551) has commercialized specialty amino-acid salt formulations that are specially designed for the purification of highly aggressive gas streams at petroleum refineries. PuraTreat R formulations can be used to remove hydrogen sulfide and — if necessary…
Vacuum insulation
At Glasstec 2006 (Düsseldorf, Germany; October 24–28), the Fraunhofer Institute for Silicate Research (ISC; Würzburg, Germany; edlinks.chemengonline.com/6519-553) unveiled a prototype for a new vacuum-insulated window that promises to save energy. The window — consisting of two glass panes separated by…
Making cement while destroying solid wastes reduces pollution
Large reductions in the emission of pollutants have been reported in the operation of a novel type of municipal solid-waste treatment plant. A group from the Hong Kong University of Science and Technology’s Dept. of Chemical Engineering (edlinks.chemengonline.com/6518-535) has…
How to boost H2 output from biomass gasifiers
A promising method for producing hydrogen involves the gasification of biomass with steam. To enhance the concentration of Hâ‚‚ in the ensuing mixture of combustible gases, a carbon dioxide sorbent can be used in situ; calcium oxide is commonly…
Bioethanol
Over the last three years, DuPont (Wilmington, Del.; edlinks.chemengonline.com/6518-552) has been developing technology to break down the complex sugar matrix of corn stover as a means for making ethanol from cellulose in high yield. Although there is more research to…
