Two waste products — carbon dioxide and industrial wastes — are combined to obtain marketable mineral products in a process being developed by startup company CarbonX Inc. (Santa Barbara, Calif.; www.carbonxinc.com). The process produces precipitated calcium carbonate (PCC) and silica from such wastes as steel industry slag and flyash from lignite-fired power plants, cement kilns and municipal...

A new system for detecting chemical or biological contaminants in water is made possible by analyzing the swimming pathways of one-celled protozoa that are introduced into the water sample. Alterations of the protozoa’s swimming mechanics, relative to a clean water control, indicate the presence of toxins. The Swimming...

  Betaine production A new process that produces natural betaine is being scaled up by Novasep Process (Pompey, France; www.novsasep.com) and Danisco (Copenhagen, Denmark; www.danisco.com). The plant will be the first to exploit a new extraction process that uses vinasse — a byproduct of sugar-beet-derived bioethanol. The process incorporates Daniscos proprietary NS2P chromatography technology...

Catalyst recycling A new process for selectively dissolving either palladium or gold from mixed-metal catalyst systems could offer a way to improve recycling of those materials. In traditional noble-metal recycling with aqua regia (mixture of nitric and hydrochloric acids), metals are often dissolved together, which introduces impurities into the recycled metals. Now scientists at the Georgia Institute of...

Next spring, Exelus, Inc. (Livingston, N.J.; www.exelusinc.com) plans to pilot a new process that converts crude bioethanol (beer) into Bio-Alkylate — a fuel that is chemically identical to gasoline. New Renewable Fuel Standards (RFS) of the U.S. Environmental Protection Agency (EPA; Washington, D.C.) call for increasing the amount of ethanol that can be added to gasoline to 15 vol.% (so-called E15...

At last month’s Sulfur 2010 Conference (November 1–4; Prague, Czech Republic), Haldor Topsøe A/S (Lyngby, Denmark; www.topsoe.com) introduced its latest sulfuric-acid catalyst, VK-701 Leap5, which promises to help operators of sulfuric acid plants meet more-stringent SO2-emission limits. When used in the final pass of single absorption H2SO4 plants, VK-701 Leap5 reduces SO2 emissions by...

A demonstration plant for a biological process that produces ethanol and 2,3 butanediol (2,3-BD) from the offgases of industrial plants will be started up in the third quarter of 2011 at a steel mill operated by Bao Steel (Shanghai). Developed by LanzaTech (Auckland, New Zealand; www.lanzatech.co.nz), the process will produce about 100,000 gal/yr of ethanol from a slipstream of stack gases, says Mike...

A nanotechnology-based, bottom-up approach to synthesizing catalysts for converting natural gas to ethylene could enable an alternative to the steam-cracking of crude oil, an energy-intensive process conventionally used to produce ethylene, the world’s most valuable commodity chemical. Scientists at the startup Siluria Technologies Inc. (San Francisco, Calif.; www.siluria.com) have developed a...

Professor Shu Kobayashi, University of Tokyo (Tokyo, Japan; www.s.u-tokyo.ac.jp), has discovered that bimetallic nanoclusters can catalyze the oxidation of alcohols. Kobayashi’s group has demonstrated the ability to control the reaction pathways of alcohol oxidation to aldehydes, carboxylic acids or esters using nanoclusters composed of a few to...

A miniaturized electron spin resonance (ESR) spectrometer developed by Active Spectrum Inc. (Foster City, Calif.; www.activespectrum.com) can facilitate studies of chemical species with unpaired electrons, such as organic free radicals and transition metal complexes. Available in both online and benchtop models, the Micro-ESR spectrometer greatly reduces the size, cost and complexity of ESR measurements...

In order to shift the country’s energy base from petroleum, the Indonesian government has implemented a policy aimed at shifting to coal. Because low-rank coal (LRC) accounts for about 80% of the nation’s coal resources, effective utilization of these reserves will be vital to its energy security. A step in this direction is being taken by JGC...
