A cleaner, more-efficient process for making high-grade steel

Phosphorous impurities in steel can lead to detrimental properties, such as reduced hardness and resistance to corrosion. Sumitomo Metal Industries, Ltd. (SMI; Tokyo and Osaka, Japan; www.sumitomometals.co.jp) has enhanced its SRP (simple refining process) for removing phosphorous from pig iron…

Direct ammonia synthesis at room temperature

Researchers at the University of Tokyo (Japan; park.itc.u-tokyo.ac.jp/nishiba/index.html) have developed a new catalyst that enables the direct synthesis of ammonia at ambient conditions. The breakthrough is a step toward an alternative to the energy-intensive, century-old Habar-Bosch process, which requires high…

Scaleup for a new process to make Bio-Alkylate

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…

A new catalyst reduces SO2 emissions from H2SO4 plants

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…

New catalyst approach for methane-to-ethylene conversion

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…

Nanoclusters that selectively catalyze oxidation reactions

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…

Miniature ESR spectrometer facilitates study of free radicals

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…
