Salts of alkaline-earth metals have been shown to catalyze reactions for the selective formation of carbon-carbon bonds, by chemistry professor Shu Kobayashi and colleagues at the University of Tokyo ( The research, supported by the Japan Science and Technology Agency (Tokyo), promises to deliver alternatives to conventional catalysts that contain toxic, scarce and expensive...
April 1, 2009
Arkema (Colomes, France; and hte (Heidelberg, Germany; have successfully concluded a research collaboration aimed at identifying new catalysts for the conversion of glycerol — a byproduct of biodiesel production — to acrolein (2-propenal) and acrylic acid. The collaboration, which started last year, utilized hte’s proprietary parallel testing technology...

Primary amines are made in high yield by a palladium-catalyzed allylic amination reaction developed by Shu Kobayashi, a chemistry professor at the University of Tokyo (Japan; The reaction uses aqueous ammonia as the nitrogen source — the first time this has ever been achieved, disproving a 30-year old theory that allylic...
March 1, 2009
Mitsubishi Chemical Corp. (MCC; Tokyo, Japan; has developed a new technology for producing 1,3-butadiene (butadiene) from waste butenes using a self-developed, proprietary catalyst. The process has been pilot tested (200-ton/yr capacity) at MCC’s Mizushima site in Japan, and the firm plans to complete process design this year with the aim to commercialize the technology by 2010...
March 1, 2009
A photocatalyst that is more active for decomposing volatile organic compounds (VOCs) with visible light than existing catalysts has been developed by researchers from the New Energy and Industrial Technology Development Organization (NEDO; Kawasaki City, Japan) in a project lead by professor Kazuhito Hashimoto at the University of Tokyo. The catalyst — a copper ion supported tungsten oxide —...

Mitsunori Shimura and colleagues at the R&D Center of Chiyoda Corp. (Yokohama, Japan; have developed a new catalyst for producing a synthesis gas (syngas; hydrogen and carbon monoxide) from steam reforming of methane. The catalyst consists of precious metals selectively loaded on the surface of the firm’s commercial, egg-shell-shaped support, which results in an effective...
January 22, 2009
The Dow Chemical Co. (Midland, Mich; and Süd-Chemie AG (Munich, Germany; today announced an agreement to research alternative routes to produce chemicals to help reduce dependence on traditional sources of oil and gas. The collaborative research aims to convert synthesis gas (syngas; H2 + CO) into building-block chemicals in a more...

Evonik Industries AG (Essen, Germany;, has started building a catalyst manufacturing plant, for producing precious-metal powder catalysts, in Shanghai, China. The plant will start operation in the fourth quarter of 2009. Precious-metal powder catalysts are used in the synthesis of pharmaceuticals, fine chemicals and industrial chemicals, where performance criteria such as high selectivity...

To further strengthen its presence and services to clients in Latin America, Haldor Topsøe (, a supplier of heterogeneous cataysis and process supplies has opened a subsidiary in Argentina...øe-subsidiary-in-Latin-America_4326.html
November 1, 2008
Researchers at the Max-Planck-Institut für Kohlenforschung (Mülheim, Germany; have demonstrated that solid acids are powerful catalysts for the hydrolysis of cellulose dissolved in an ionic liquid. Even the cellulose fraction of wood, which is predominantly lignocellulose, can be hydrolyzed by the technique, says Ferdi Schüth, leader of the institute’s...
November 1, 2008
Researchers at the Dalian Institute of Chemical Physics (China; and the University of Delaware (Newark; are developing a tungsten-carbide/nickel catalyst that degrades cellulose into polyols at 245°C and 60 atm. The catalyst is believed to facilitate hydrolysis and hydrogenation...
November 1, 2008
Researchers at the National Institute of Advanced Industrial Science and Technology (AIST; Tsukuba, Japan;, and the University of Tokyo have developed new photocatalysts that are more efficient at decomposing volatile organic compounds (VOCs) than the commonly used titanium dioxide. The catalysts — tungsten trioxide promoted with palladium or copper — decompose VOCs, such as...

A method for identifying less-expensive catalysts, compared to commercial, precious-metal-based ones, is starting to deliver results by researchers at the Center for Atomic-scale Materials Design, Dept. of Physics, Technical University of Denmark (CAMD; Lyngby; and their collaborators. The computer-aided method ultimately generates a plot of cost-of-metal versus heat of adsorption for the...

In order to make ethanol from cellulose, the polysaccharide must first be broken down into sugars (saccharrified) that can be fermented. Normally, this hydrolysis reaction is catalyzed by sulfuric acid or enzymes. However, H2SO4 -based hydrolysis generates spent acid, which has to be separated and regenerated before recycling; and enzyme-driven methods have long reaction times and require pretreatment to...

A new metal carbide F-T catalyst has been developed by Oxford Catalysts Limited (Oxford, U.K., for making second-generation biofuel in small-scale microchannel reactors. The catalyst was produced...
July 15, 2008
The use of palladium on carbon powder supports (Pd-CP) has traditionally been a commercially viable means of catalyzing deprotection reactions, despite also requiring substantive quantities of precious metal and limiting the selection of solvents due to low hydrogenation activity. However, with a new series of Pd-CP catalysts, BASF’s catalyst division (Iselin, N.J.; has...
