      Biomass has come center stage in the pursuit of reduced dependence on finite - not to mention geopolitically sensitive - quantities of fossil fuels such as petroleum, coal and natural gas. And while ethanol produced from corn is one promising path for biomass, it is by no means the only one. The number of known viable raw materials is vast, and the assortment of feasible downstream...

Researchers at Kanagawa University (Yokohama, Japan; edlinks.che.com/6517-535) have developed a three-phase emulsification technology for making stable emulsions of diesel-fuel oil in water. Tests with the emulsion (involving a 30-ton truck) show that fuel-combustion efficiency is increased by 10-15% compared to conventional diesel fuel, and the emissions of dust and nitrogen oxides are reduced by 95 and...

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...
