The conventional way to make molded ceramic compontents involves the use of an organic binder (about 10-15 wt.%) to keep the shape of the fine ceramic powders. The binder is then burned off during the sintering process; this not only requires additional energy to burn out the binder (which may also release toxic gases), but finished ceramic...

Up to now, light-cycle oil (LCO) produced from desulfurized vacuum-gas oil has been used as a base for heavy oil or for blending with straight gas oil (SGO). But a decreasing demand for heavy oil, combined with LCO’s drawbacks as a blending material (such as low cetane number), is drying up these outlets for LCO. Furthermore, existing technology for hydrotreating LCO is energy intensive and consumes...

Although there has been big surge in biodiesel production recently, such fuels are not without problems of their own, such as low mileage, poor performance at lower temperatures, and adverse effects on engine components. Also, the production process for making biodiesel — the methyl esterification of fatty acids derived from vegetable oils (such as palm and rapeseed)...

By repetitive dividing and merging of laminar flows within complex patterns of narrow (25–40 µm) channels, static micromixers are very efficient at making homogeneous mixtures. However, the narrow channels are susceptible to clogging, and the cost to precisely manufacture the complex patterns remains high. Yamatake Corp. (Tokyo, Japan; edlinks.che.com/6518-536) has patented a new micromixer...

Cellulose accounts for about 40% of the planet’s total photosynthesis yield (about 1.8 trillion m.t./yr), but the material has not been fully utilized as a chemical resource so far. That’s because the methods currently available for converting cellulose into useful chemicals have drawbacks, such as: low activity, for degradation by enzymes; poor selectivity and difficult separations, for...

This month, JFE Steel Corp. (Tokyo, Japan; edlinks.che.com/6517-532) started up a new production plant that produces 100 m.t./yr of solar-grade (SOG) silicon (Si) from crude Si metal. The company also started to design a 500-1,000-m.t./yr plant for making SOG Si, and plans to start operations by March 2008. Up to now, JFE Steel used directional-solidification (DS), which aligns the Si...

Brown coal accounts for about half the world’s coal reserves. Although it contains less ash and sulfur than bituminous, brown coal contains more water, which reduces its heating value. To take advantage of this “greener” source of fuel, Kobe Steel Ltd. (Tokyo; edlinks.che.com/6516-532) has developed the upgraded brown coal (UBC) process, which increases the heat value of standard brown...

Mitsubishi Heavy Industries Co. (MHI; Mihara, Japan; edlinks.che.com/6515-531) has developed an integrated piping-and-instrument system, called M-iPIS, which makes small, complex piping systems from a single plate block. Analogous to the manufacturing of integrated circuit boards, M-iPIS realizes not only cost and space savings, but also produces a gas-tight system with rapid heating and cooling...

Professor Yasutaka Ishii, and colleagues from the Dept. of Applied Chemistry, Kansai University (Osaka, Japan; edlinks.che.com/5830-535), has developed a three-step production process to make epsilon-caprolactam (CPL) from cyclohexane. Compared to alternative methods, the process has a higher CPL yield, generates less waste, and avoids the use of corrosive reagents, says Ishii. The convectional route to...

Toyo Engineering Corp. (TEC; Tokyo; edlinks.che.com/5829-536) has developed a new, cryogenic process for extracting natural-gas liquids (NGLs; ethane, propane, butane and other hydrocarbons) from liquefied natural gas (LNG). The Coreflux-LNG process boasts an ethane recovery efficiency of around 98%, compared to 90–93% efficiencies achieved by alternative processes, claims TEC. The process will be...

Kokusan Co. (Tokyo; edlinks.che.com/5827-531) has developed a new type of emulsifier that uses centrifugal force to drive mixtures through specially designed nozzles. The system is said to be less complex than conventional high-shear mixing devices, and operates at much lower pressures than other nozzle-based systems, which typically require a piston pump to force products through stationary or variable...

The conventional way to dye textiles is by the so-called dip process, whereby cloth is first immersed into a vat of the dying medium, then removed and dried. The dye is then thermally fixed to the textile by heating to 150°C, and the excess dye removed by washing and drying steps. These wash and dry steps use large volumes of water, which then becomes contaminated with dye, and the drying and fixing...
