A post-combustion process capable of separating CO2 from fluegas at one-third the cost of alternative separation processes has been developed by Inventys Thermal Technologies, Inc. (Burnaby, B.C., Canada; www.inventysinc.com). Tradenamed VeloxoTherm (VX), the patented process is now being tested together…
A biological process for the destruction of sodium oxalate at Alcoa’s Kwinana alumina refinery in Western Australia has proven to be an extremely robust technology. Alcoa’s residue technical manager, David Cooling, says the plant has achieved an oxalate destruction rate…
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…
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…
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…
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…
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…
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…
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…
A green hydrometallurgical process for recovering gold from ore, developed by Haber, Inc. (Arlington, Mass.; www.habercorp.com), may make its commercial debut in Suriname. Albert Conti, Haber’s CEO, says the Republic of Suriname has made a commitment to develop a strategic…
