Next month, Taiyo Kagaku Co. (Yokkaichi, Japan; edlinks.che.com/7370-563) will start up a 20-m.t./yr plant — said to be the world’s first — for the production of mesoporous silica. Taiyo Kagaku developed the new production process based on technology first introduced by Toyota Central R&D Laboratories, Inc. (Aichi, Japan; CE, April 2004, p. 17). The commercial grade mesoporous silica...

Biotechnology samples, such as proteins, nucleic acids, biological specimens and pharmaceuticals, are typically stored frozen to extend their shelf life. However, a problem that has plagued researchers for decades is that the buffers used to maintain the pH of the samples lose their efficacy as samples are cooled. Low-temperature biophysical and bioanalytical techniques can also be affected by pH...

The amount of crude oil remaining in depleted oil fields has been estimated to be about 50 – 80% of the total estimated oil reserves. In the past, CO2 has been injected into such wells for enhanced-oil recovery — a technique that displaces the oil and stores the greenhouse gas. Now, a completely different approach to monetizing the carbon is being considered by Inpex Holdings Inc. (Tokyo...

The blood-cholesterol-lowering effects of beta-glucan — the soluble oat fiber — is well known, but up to now it has been difficult to obtain beta-glucan-rich fractions that are feasible for food applications, according to VTT Technical Research Center (Espoo, Finland...

In Malaysia, the raw material for biodiesel production has been palm oil. However, making biodiesel can conflict with the oil’s use as food, and growing palm oil (even for food) has caused the destruction of tropical forests in Borneo, Sumatra and other regions. A team from the Dept. of Chem. Eng. at the Universiti Teknologi Petronas, (Perak, Malaysia...

Integrated Biodiesel Industries, Ltd (IBI; Sao Paulo) has signed a Letter of Intent with port operator Terminal Puerto Rosario S.A. (TPR) to build a 60,000-m.t./yr biodiesel plant inside its facilities in the city of Rosario, Argentina. TPR will offer existent infrastructure such as land, storage tanks with...

    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...

A new catalyst that promises to cut the cost of producing biodiesel fuel from vegetable oils and animal fats by 30% has been developed by Victor Lin, a chemistry professor at Iowa State University (Ames, Iowa; edlinks.che.com/6898-537). The solid catalyst replaces the soluble, sodium methoxide catalyst that is currently used for the transesterification of oils in the production of biodiesel...

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...

Hydrogen is produced directly from biomass and other carbonaceous materials, with simultaneous capture of carbon dioxide, in a process being developed by Energy Quest, Inc. (Edmonton, Alta., Canada; edlinks.che.com/6897-533). In the PyStR (pyrolytic steam reforming) process, crushed or shredded feedstock and steam are fed directly into a circulating bed of calcium oxide. The fuel is pyrolized at about...

Paques B.V. (Balk, Netherlands; edlinks.che.com/6897-535) has developed a cost-effective biological process (flowsheet) for removing phosphates and nitrogen from wastewater. The first commercial installation to use the new process officially opened last month at Aviko (Steenseren, Netherlands), where it is treating 3,000 m3/d of wastewater from potato processing. The plant is owned and operated by...

The standard way to produce ethanol from agricultural waste involves acid hydrolysis to convert hemicellulose to glucose, which is then fermented to obtain ethanol. However, cellulose in the waste is not converted, so cellulase enzymes are generally used to hydrolyze the cellulose to fermentable sugars, a slow and costly process. Researchers at the U.S. Dept. of Agriculture’s...

A process that promises to improve the economics of ethanol production by coproducing a marketable adhesive is being developed by the USDA's Dairy Forage Research Center (Madison, Wis.; edlinks.che.com/6896-534). Another benefit is that ethanol is made from cellulosic material in a single reactor, rather than the normal two-step method of breaking down cellulose to obtain glucose, then fermenting the...
