Carbon nanotube (CNT) membranes developed by researchers at Rice University (Houston; www.rice.edu) could have applications as nanoparticulate filters, and as nanoscale scaffolds for catalysts. The devices are silicon dioxide wafers with laser-bored holes (~500-µm dia.). The holed wafers are subjected…
Kazuhiro Sayama and colleagues at the Solar Light Energy Conversion Group at Energy Technology Research Institute, National Institute of Advanced Industrial Science and Technology (AIST; Tsukuba, Japan; unit.aist.go.jp/energy), have developed a cesium-treated tungsten oxide photocatalyst that shows a 19% quantum…
Last month at the Global Refining Summit (Rotterdam, the Netherlands; May 17–19), Swapsol Corp. (Monmouth Junction, N.J.; www.swapsol.com) introduced a completely new sour-gas-cleanup process that reduces hydrogen sulfide levels below detectable levels (under 4 ppb) while reacting with carbon dioxide…
A recently developed hydrogen generation unit combines an autothermal, fluidized-bed methane reformer with a metal hydride compressor. Aside from combining the reforming, H2 separation and compression, which are part of conventional H2 generation (top diagram), the engineers behind the system…
Algae has recently become an R&D focus for making third-generation biofuels because these oil-containing microorganisms reproduce so quickly and can be grown away from arable farmland. However, getting the oil from the cells — and the water — is energy…
Oasys Water Inc. (Cambridge, Mass.; www.oasyswater.com) has commercialized a forward-osmosis (FO) membrane as the next step toward introducing its lower-cost desalination and water-reuse technology. The membrane, developed by Professor Menachem Elimelech, chair of chemical engineering at Yale University (New Haven,…
At the Hannover Messe 2010, Alumina do Norte do Brasil S.A. (Alunorte; Barcarena, Brazil; www.alunorte.net) and Outotec Oyj (Espoo, Finland; www.outotec.com) received the X Prize (special recognition) for energy efficiency in alumina production. The award, part of the German Energy Agencys…
Novozymes A/S (Bagsvaerd, Denmark: www.novozymes.com), COFCO Ltd. (www.cofco.com/en) and Sinopec Corp. (both Beijing, China; english.sinopec.com) signed a Memorandum of Understanding covering the next steps towards commercialization of cellulosic biofuel in China. As part of the agreement, COFCO and Sinopec will build a…
A biomass-to-liquids (BTL) demonstration plant jointly operated by the Oxford Catalysts Group Plc. (Abingdon, U.K.; www.oxfordcatalysts.com) and the Portuguese incorporated holding company, SGC Energia (SGCE; www.sgc.pt), for the small-scale distributed production of biofuels has achieved some significant commissioning milestones. The…
Foster Wheeler AG (Zug, Switzerland; www.fwc.com) announced today the successful start of commercial operation of a large-scale, 125-MWe (385-MWth), circulating fluidized-bed (CFB) boiler island delivered to Kaukaan Voima Oy, in Finland. Kaukaan Voima Oy is owned by Pohjolan Voima Oy…
