acid technology will be employed in both units for the conversion of hydrogen sulfide to sulfuric acid. The first plant will be constructed for Yukos at the company’s refinery complex in Angarsk, Russia, by end of 2006. The Angarsk unit will have a 180 tonne/day sulfuric acid capacity. Haldor will construct the second unit for Naftan at the company’s refinery in Novopolotsk, Belarus, and will yield 223 tonne/day of sulfuric acid. Completion is due by 2007.

NEW TECHNOLOGY Catalytic membrane reactor for PEMFCs Noritake has developed a catalytic membrane reactor for fuel cells using reformed gas. The reactor contains a nano-porous membrane coated with a CO-selective platinum catalyst.

One of Celanese’s vinyl acetate monomer (VAM) manufacturing facilities has started using a new catalyst co-developed by Celanese and Symyx Technologies. Celanese will provide milestone payments to Symyx based on the first commercial deployment of the catalyst technology, and will pay royalties for vinyl acetate production upon the deployment of the catalyst at a second company plant.

Catalytic breakup of cellulose Japanese workers have shown that cellulose can be catalytically converted to glucose and hydrogen by heating in water at 190°C. This glucose can be reduced to sugar alcohols and then converted to liquid fuels. The catalyst is a platinum/ ruthenium alloy supported on silica or alumina.

synthesis process developed by Codexis also consumes less energy and produces fewer by-products while yielding more products. ICIS Chemical Business, 17 Jul 2006 (Website: http://icischemicalbusiness.com)

BASF: innovative processes A novel technology, founded using the biocatalyst dehydrogenase, has been developed by BASF for making novel optically active styrene oxides and aliphatic alcohols. The technology is now being used at the production level to make highly pure materials that serve as key building blocks in the drug sector. The company has also developed a comprehensive manufacture process for the chemical and life sciences industries. The technology can produce a range of products including speciality amines and heterocycles. BASF markets its line of over 20 ionic liquids under the name Basionics.

Novel perovskite catalysts for fuel reforming Workers at Purdue and Notre Dame have tailor-made a perovskite catalyst for generating hydrogen from JP-8 fuel for use in fuel cells. The basic structure is lanthanum ferrate doped with cerium and nickel. Fuelcells Bulletin, Jul 2006, (7), 12-17

New ferrous ammonia synthesis catalyst in China With the help of the Zhejiang University of Technology, SinoGerman Liaoning Panjing South Chemical Liaohe Catalyst Co Ltd has developed the Amomax-10 oxidation and Amomax-10H pre-reduction catalysts for use in ammonia synthesis. The new ferrous catalysts were successfully appraised by the China Petrochemical and Chemical Industry Association on 25 May 2006 and have now entered commercial production. Advantages include low activation temperatures, short reduction times, lower bed resistance, energy savings, and safe operation. China Chemical Reporter, 6 Jul 2006, 17 (19), 14

Codexis scoops EPA award The US Environmental Protection Agency has awarded Codexis the 2006 Presidential Green Chemistry Challenge Award for a suite of biocatalysts used in the synthesis of Lipitor. The biocatalaysts produce a key hydroxynitrile intermediate that serves as chiral building block for atorvastatin, the active ingredient of cholesterol-lowering drug Lipitor. The

Novel LAO technology makes commercial debut Linde AG, in partnership with Saudi Basic Industries Corp (Sabic), has announced that its new linear-alphaolefin (LAO) technology will be initially employed at a plant being built by Linde for Jubail United Petrochemical Co in Al-Jubail, Saudi Arabia. The novel process for selective catalytic synthesis of LAOs from ethylene is claimed to be economical. Dubbed alpha-Sablin, the novel LAO process involves a two-component catalyst system in the oligomerization of ethylene. The two catalysts are a patented zirconium compound and a commercially available aluminium alkyl. The novel LAO technology is a single-step system where chain growth and termination is processed simultaneously in the same reactor. Chemical Engineering Progress, Jul 2006, 102 (7), 13
