Making crude oil from coal, without mining or combustion
An underground coal-to-liquids (UCTL) technology is undergoing pilot testing at Oak Park, near Melbourne Australia, where a metric ton of brown coal is expected to yield about one barrel of oil suitable for use as refinery feedstock on an oil-parity…
A new approach to maintaining tubular heat exchangers
At the 2nd Annual ChemInnovations Conference and Expo (Houston; September 13–15), Hemi-O Technologies LLC (Corpus Christi, Tex.; dixonengineering@gmail.com) introduced its patent-pending technology that enables external access to individual tubes in a heat exchanger while the exchanger is in service and…
Dewatering enzymes boost ethanol production efficiency
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…
A new heterogeneous catalyst for low-temperature VOC decomposition
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…
Biomass pretreatment
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.…
A simpler process to make PX from LCO
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;…
Carbon storage and electricity generation project gets DOE funding
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…
September Chementator Briefs
Phosgenation scaleup At the end of July, Bayer MaterialScience AG (BMS; Leverkusen, Germany; www.bayerbms.com) successfully tested its new gas-phase phosgenation technology at a new plant being commissioned for making toluene diisocyanate (TDI) — a raw material for making polyurethane —…
Boost heavy metal recovery from wastewater with graphite-oxide coated sand
A process to greatly enhance the ability of sand to filter heavy metals from water has been developed by researchers from Monash University, of Melbourne, Australia (www.monash.edu.au), Rice University (Houston; www.rice.edu) and Nanoholdings LLC (Marietta, Ga.; www.nanoholdings.com). Historically, the researchers…
Microbe-based process for GBL nears commercialization
Metabolix Inc. (Cambridge, Mass.; www.metabolix.com) has successfully demonstrated and completed research and development for scaleup on a fermentation process that produces gamma -butyrolactone (GBL) from genetically engineered bacteria. The process is built upon the company’s technology for engineering metabolic pathways…
