A new type of coal-fired IGCC-power plant to be demonstrated

Although brown coal accounts for about 25% of Australia’s energy supply, it has a high moisture content and, when burned, is a high emitter of carbon dioxide (above 1,200kg/MWh). To address this challenge HRL Ltd. (Melbourne, Australia; edlinks.chemengonline.com/6897-531) has developed…

Liquified DME cuts energy costs for dehydrating solids

A dehydration process — which uses about half the energy required by thermal methods for drying brown coal or sludge — is being developed by the Central Research Institute of Electric Power Industry (Tokyo, Japan; edlinks.chemengonline.com/6897-532). The process uses liquefied…

This pyrolysis process coproduces hydrogen and carbon dioxide

Hydrogen is produced directly from biomass and other carbonaceous materials, with simultaneous capture of carbon dioxide, in a process being developed by Energy Quest, Inc. (Edmonton, Alta., Canada; edlinks.chemengonline.com/6897-533). In the PyStR (pyrolytic steam reforming) process, crushed or shredded feedstock…
