More For Your Money

    Portable and fixed detectors for toxic and flammable gases are offering more choice and better value for the money, say experts, thanks to technology developments and strong market competition. In Europe, competition triggered by consolidation in the last…

How to boost H2 output from biomass gasifiers

  A promising method for producing hydrogen involves the gasification of biomass with steam. To enhance the concentration of Hâ‚‚ in the ensuing mixture of combustible gases, a carbon dioxide sorbent can be used in situ; calcium oxide is commonly…

Bioethanol

Over the last three years, DuPont (Wilmington, Del.; edlinks.chemengonline.com/6518-552) has been developing technology to break down the complex sugar matrix of corn stover as a means for making ethanol from cellulose in high yield. Although there is more research to…

The Mass Balance

    More and more, it is recognized that business and science are interwoven, and that these disciplines can complement each other to achieve corporate goals. In the chemical process industries (CPI), a noteworthy role is that of engineering in…

Making cement while destroying solid wastes reduces pollution

  Large reductions in the emission of pollutants have been reported in the operation of a novel type of municipal solid-waste treatment plant. A group from the Hong Kong University of Science and Technology’s Dept. of Chemical Engineering (edlinks.chemengonline.com/6518-535) has…

Broader Horizons for Biomass  

      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…

Fire turns this polymer composite into a rigid protective barrier

A new-type of polymer composite has recently been commercialized by Ceram Polymerik Pty Ltd. (Melbourne, Australia; edlinks.chemengonline.com/6517-533) for passive fire-protection applications. Passive fire protection consists of using a material or structure that confines fires, giving people more time to escape…

Efforts to reduce the cost of Si-based solar cells

Most of today's solar cells are made from silicon wafers cut from blocks of crystals. The wafers are typically 0.2-0.25-mm thick, yet most of the photon-to-electricity conversion takes place in the outermost 0.02 mm of the wafer. In an effort…
