At the 2nd Annual ChemInnovations Conference and Expo (Houston; September 13–15), Hemi-O Technologies LLC (Corpus Christi, Tex.; [email protected]) introduced its patent-pending technology that enables external access to individual tubes in a heat exchanger while the exchanger is in service and…
A technique that improves the efficiency of ethanol plants by lowering the cost of dewatering the byproduct stillage (a slurry of corn solids and water) from the fermentation process has been developed by scientists at the U.S. Department of Agriculture’s…
Professor Yuki Taniguchi at the Chemicals Research Institute, Tokyo Institute of Technology (Japan, www.res.titech.ac.jp/~gosei/taniguchi/index.html) has developed a new catalyst system that decomposes volatile organic compounds (VOCs) at lower temperatures than that required by conventional catalysts. The SILP (supported ionic liquid…
Impending standards requiring that cellulosic ethanol be used in gasoline blending have focused attention on building a capacity for bioethanol from non-food sources. In a development that may begin to meet that need, a plant employing a unique method for…
China produces about 98% of the world’s electrolytic manganese metal (EMM), a vital ingredient used in specialty steels, aluminum and electronics. In contrast, the U.S. produces no EMM, says Nick Weir, an executive with U.S. American Manganese Inc. (AMY; White…
A 60% reduction in the sludge volume was achieved at the sewage treatment plant of Noboribetu City, Hokkaido, Japan, after installing a Bio-Diet SBD-1200 system from Nippon Steel Kankyo Engineering Co. (NSKE; Tokyo, www.nske.co.jp). The demonstration unit, developed at the…
A rapid pressure-swing-adsorption (rPSA) system to separate carbon dioxide from fluegas is being developed by W.R. Grace & Co. (Columbus, Md.; www.grace.com) and three partners under a $3 million grant from the U.S. Dept. of Energy (DOE; Washington, D.C.; www.energy.gov).…
Cellulosic biomass pretreated with ammonia undergoes structural changes that make it more susceptible to enzymatic attack, scientists at Los Alamos National Laboratory (Los Alamos, N.M.; www.lanl.gov) and collaborators at the Great Lakes Bioenergy Research Center (Madison, Wisc.; www.glbrc.org) have found.…
Anew process to make BTX (benzene, toluene and xylenes) from light cycle oil (LCO), an oversupplied product of petroleum refineries that can supplement the dwindling supply of BTX precursors, is being developed by JX Nippon Oil & Energy (JX Energy;…
A project aimed at using geothermal heat to power an electricity-producing turbine with supercritical carbon dioxide has received a $5 million grant from the U.S. Dept. of Energy (DOE; Washington, D.C.; www.energy.gov). The project also incorporates an element of CO2…
