The cost of producing ethanol promises to be reduced by 50% through a process being developed by TNO (Zeist, Netherlands; edlinks.che.com/6894-536). The reason for the dramatic cut is that ligno-cellulosic material is hydrolyzed in a single step, using concentrated sulfuric acid. In contrast, conventional hydrolysis is a two-step process in which...

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...

Cleaning the interior of firetubes in oil-, biomass- or coal-fired boilers is a time-consuming task that can normally be done only when a boiler is offline. Now, a system that can do the job automatically while the boiler is in operation is available from Optimum Environmental Technologies B.V. (Arnhem, Netherlands; edlinks.che.com/6894-538). Optimum's Automatic in-line Pipe Cleaning System...

Another online boiler-cleaning system, in this case for coal-fired watertube boilers, is offered by GE Energy (Kansas City, Mo.; edlinks.che.com/6894-539). GE's automated system, called Powerwave+, is more efficient and less expensive than sootblowing with high-pressure steam, the commonly used online method for cleaning the...

Mitsui Engineering & Shipbuilding Co. (MES; Tokyo, Japan; edlinks.che.com/6894-540), in cooperation with Chugoku Electric Power Co. (Hiroshima, Japan), is building a pilot plant that will produce 5-m.t./d of natural gas hydrate (NGH). The plant, located at Chugoku Electric's Yanai Power Station (Yamaguchi, Japan), is a scaled-up version of MES's 600 kg/d pilot plant, which has been operating since...

Demonstration plants to test six processes for producing ethanol from non-food-based biomass will be built with support from the U.S. DOE (edlinks.che.com/6894-543). Between them, the plants will produce more than 130 million gal/yr of ethanol from cellulosic feeds, including agricultural waste and perennial grasses. DOE's goal is to make cellulosic ethanol cost-competitive...

    China's tremendous economic growth and modernization has propelled the nation to a position where its consumption of energy imports outpaces its economy. As the world's third-largest oil importer, after the United States and Japan, China imported a record-high 36.38-million tons of refined oil last year, 15.7% more than in 2005, to fuel an estimated annual economic growth of 10.7%, reports...
