  A promising method for producing hydrogen involves the gasification of biomass with steam. To enhance the concentration of H₂ in the ensuing mixture of combustible gases, a carbon dioxide sorbent can be used in situ; calcium oxide is commonly used. A research team from the Laboratory for Sustainable Technology, at the University of Sydney’s School of Chemical and Biomolecular Engineering...

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...

    Provided that they are updated when appropriate to keep them relevant, time-tested heuristics rules based upon experience, also referred to as rules of thumb, can be useful for the design, specifying and operation of several kinds of equipment used in process plants. The first and foremost heuristic rule is that the engineer should not shy away from using heuristics - and the second rule is...

      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...

Construction is underway on what is said to be the world's largest hydrogen chloride recycling plant, for Bayer MaterialScience AG (BMS; Leverkusen, Germany; edlinks.che.com/6517-536). When the unit starts up in 2008 at the Shanghai, China site, it will produce 215,000 m.t./yr of Cl₂ from HCl; this will be the first large-scale application of oxygen-depolarized cathode (ODC) technology. The HCl for the...
