Azotobacter are nitrogen-fixing bacteria that do a useful job in soil by converting N 2 to ammonia. As a side reaction they also produce hydrogen, most of which they oxidize for their own energy consumption. In a project of the…
Metabolix, Inc. (Cambridge, Mass.; www.metabolix.com) has demonstrated, in recently completed greenhouse trials, that switchgrass plants engineered using the firm’s multi-gene expression technology produced significant amounts polyhydroxybutyrate (a polyhydroxyalkanoate; PHA) bioplastics in leaf tissues. The result is said to be the…
BHR Biofuels, a subsidiary of BHR Group (Cranfield, U.K., www.bhrgroup.co.uk), has installed and demonstrated two process-intensified, full-size Biodiesel Reactor Systems at a chemical plant producing biodiesel from waste and virgin oils. The reactor systems are said to consume some 70%…
Rentech, Inc. (Los Angeles, Calif.; www.rentechinc.com) has produced its first run of jet fuel from its Fischer-Tropsch (F-T) product demonstration unit (PDU) in Commerce City, Colo. The plant produces a synthesis gas of hydrogen and carbon monoxide by steam-reforming of…
Conventional cooling systems rely on the properties of gases to cool, but common coolants are either harmful to people or the environment. A different approach is being investigated by researchers at the Dept. of Electrical Engineering, Penn State University (University…
A new metal carbide F-T catalyst has been developed by Oxford Catalysts Limited (Oxford, U.K., www.oxfordcatalysts.com) for making second-generation biofuel in small-scale microchannel reactors. The catalyst was produced using the company’s patented organic matrix combustion method, which makes it possible…
Evonik Industries AG (Essen; www.evonik.com) and SolarWorld AG (Bonn, both Germany; www.solarworld.de) have opened a new solar silicon plant in Rheinfelden (Baden, Germany). As part of the joint venture (JV) Joint Solar Silicon (JSSI), the two companies are using a…
Vogelbusch GmbH (Vienna, Austria; www.vogelbusch.com) has developed a patent-pending distributor system that it claims makes possible the adaption of simulated moving bed (SMB) chromatography for use in the pharmaceutical industry. Prior to this, SMB use has been limited to the…
