DuPont (Wilmington, Del.; edlinks.che.com/6900-531) has acquired hydrotreating technology for desulfurizing motor fuels and hydrocracking intermediate refinery streams from Process Dynamics, Inc. (Fayetteville, Ark.). The IsoTherming Hydroprocessing Technology differs from other hydrotreating processes in that hydrogen is dissolved in the liquid feed before the liquid enters the reactor, so the reactors...

Although halons (brominated or chlorinated fluorocarbons) are widely used as fire suppressants and foaming agents, they also contribute to stratospheric ozone depletion. However, halons are potentially valuable chemicals that should not be destroyed, but rather converted to reusable chemicals, says Bogdan Dlugogorski, professor of chemical engineering in the school of...

Asahi Kasei Finechem Co. (Osaka, Japan; edlinks.che.com/6900-538) has commercialized a new type of catalyst for performing asymmetric oxidation reactions. The catalyst is based on ligands having the structure of a chiral-bis-hydroxamic acid (CBHA; diagram), which was first developed by Professor Hisashi Yamamoto at the University of Chicago; Asahi Kasei Finechem subsequently developed an industrial process...

  Daicel Chemical Industries Ltd. (Osaka, Japan; edlinks.che.com/6900-540) is further developing an oxidation catalyst based on N-hydroxyphthalimide (NHPI), which was first discovered by Professor Yasutaka Ishii of Kansai University several years ago (CE, September 2000, p. 23). The catalyst, together with a small amount of metal salts (Mn or Co), can be used for the...

Rigorous temperature control is required for performing selective catalytic reactions, such as hydrogenation and oxidation (ethylene oxide production, for example), and in reactions where the chemical equilibrium is strongly temperature dependent (Claus sulfur recovery or the CO-shift reaction, for example). Up to now, catalyst-filled, straight-tube reactors have typically been used for such reactions. But...

In order to confirm the performance of its proprietary, high-severity fluid-catalytic-cracking (HS-FCC) process, Nippon Oil Corp. (Tokyo, Japan; edlinks.che.com/6899-533) plans to build a new confirmation-test plant at its Mizushima, Japan, refinery. The unit will have a treating capacity of 3,000 bbl/d when it starts operating in 2010 as part of a joint research project conducted by Petroleum...

    Glycerin has over 1,500 known end uses, including applications in cosmetics, pharmaceuticals and food products, with the U.S. market alone demanding around 600-million lb/yr. But over the next two years, biodiesel plants are expected to produce an additional 1-billion lb/yr of glycerin as a byproduct (see box below). As a result, the price of glycerin is falling as fast as biodiesel plants...

Davy Process Technology Ltd. (DPT; London; edlinks.che.com/6898-531), a Johnson Matthey company, has received the first license of its new glycerin-to-propylene glycol (GTPG) process. The first project, planned for the Ashland/Cargill joint venture (CE, June, p. 10), will produce more than 65,000 m.t./yr of PG at a yet-to-be disclosed location in Europe. Startup is expected early in 2009. The GTPG process...

The traditional way to check microbial growth in a fermentation process is to take a sample of slurry and analyze it in the laboratory, a procedure that is less than ideal because of the time delay in obtaining the information. Now, a method that does the job online, in real time, has been developed at Pacific Northwest National Laboratory (PNNL; Richland, Wash.; edlinks.che.com/6898-533). In PNNL’s...

Alumina refining by the Bayer process involves the digestion of bauxite ore with caustic soda, which produces “green liquor,” from which alumina is recovered, and a bauxite residue, called red mud, which is stored in large disposal areas. A typical refinery (2-million m.t./yr) produces about 1.4 tons of bauxite-residue per ton of alumina recovered, which translates into about 2.8-million m.t./yr of red...

What is billed as the first commercial-scale plant to produce ethanol from cellulosic feed will be built in Treutlen County, Georgia, by Range Fuels, Inc. (Broomfield, Colo.; edlinks.che.com/6898-541). The company received a construction permit from the State of Georgia last month and will shortly break ground for the plant. Scheduled for completion...
