Kobe Steel Ltd. (Kobelco; Tokyo; has developed a process to recover hydrogen from methane steam reformers with purity that is sufficiently high for use in fuel cells. The key to the process is a proprietary carbon-monoxide adsorbent for Hâ‚‚ pressure-swing adsorption (PSA), which Kobelco developed jointly with Kansai Coke and Chemicals Co. (Amagasaki, Japan). In conventional PSA...

ConocoPhillips LP (CP; Houston, Tex.; and Tyson Foods, Inc. (Springdale, Ark.) have formed an alliance to use beef, pork and poultry by-product fat to create renewable-diesel (RD) fuel that burns cleaner than conventional diesel. The production technology uses a thermal depolymerization (TDP) process developed by CP that co-processes animal fat (supplied by Tyson) with hydrocarbon...

“Green” diesel fuel that can be blended with petroleum-derived diesel fuel has been produced from vegetable oil in a process developed jointly by UOP LLC (Des Plaines, Ill.; and Eni S.p.A. (Milan, Italy). The fuel is a “premium diesel blending component” for a refinery, with a boiling range comparable to typical diesel products and a cetane number of 80...

A coal-gasification reactor that resembles a metals smelter and operates in two cycles (oxidation and reduction), alternately producing hydrogen and syngas, is being developed by Diversified Energy Corp. (Gilbert, Ariz.; and Alchemix Corp. (Carefree, Ariz.). In the oxidation cycle (diagram, left), steam is injected into a bath of molten iron-tin alloy to form iron oxide and...

Following up on its success with the world’s first commercial plant to use a new oil-recycling process, Puralube GmbH (Elsteraue, Germany; plans to build a second plant near the first one, in Zeitz/Elsteraue. Scheduled for startup at the end of 2008, it will have the same capacity as the first, at approximately 80,000 m.t./yr of used oil. Christian Hartmann...

In order to produce ethanol with nearly 100% purity from fermentation broth, conventional processes use a two-step distillation operation, which accounts for almost 55% of the total energy requirements. Therefore, improving the concentration step is a key to reducing the costs of making bioethanol. A promising step in this direction is a new gating membrane being developed by professor Shin-ichi Nakao at...

If every vehicle in the U.S. ran on fuel made primarily from ethanol instead of gasoline, the number of respiratory-related deaths and hospitalizations would likely increase, according to a study by Mark Jacobson, associate professor of civil and environmental...
April 1, 2007
The cost of producing ethanol promises to be reduced by 50% through a process being developed by TNO (Zeist, Netherlands; The reason for the dramatic cut is that ligno-cellulosic material is hydrolyzed in a single step, using concentrated sulfuric acid. In contrast, conventional hydrolysis is a two-step process in which...

Mitsui Engineering & Shipbuilding Co. (MES; Tokyo, Japan;, in cooperation with Chugoku Electric Power Co. (Hiroshima, Japan), is building a pilot plant that will produce 5-m.t./d of natural gas hydrate (NGH). The plant, located at Chugoku Electric's Yanai Power Station (Yamaguchi, Japan), is a scaled-up version of MES's 600 kg/d pilot plant, which has been operating since...

A process that yields hydrogen by using solar energy to split water has received one-third of the €1 million Descartes prize, awarded annually for research financed by the European Commission (Brussels, Belgium). The process was developed under the Hydrosol project, headed by the Chemical Process Engineering Research Institute, Center for Research and Technology-Hellas...

Demonstration plants to test six processes for producing ethanol from non-food-based biomass will be built with support from the U.S. DOE ( Between them, the plants will produce more than 130 million gal/yr of ethanol from cellulosic feeds, including agricultural waste and perennial grasses. DOE's goal is to make cellulosic ethanol cost-competitive...
April 1, 2007
A fungus that is said to be more effective than baker's yeast for the conversion of waste to ethanol has been discovered by researchers at Boras University College (Sweden; The fungus, a saprophyte (of the zygomycetes...
