Genencor in India Danisco A/S’s division Genencor has opened a production plant in Haryana and a sales office in Mumbai to expand its operations in India. The Haryana plant will produce enzyme blends for the local industries such as food and beverages, animal feed, fuel ethanol, laundry detergents, textiles, and grain processing. Over 20 people will be initially employed in the country. HPC, Household and Personal Care Today, Jul 2008, (2), 45

Diesel from wood in Saxony In Apr 2007 the first refinery in the world capable of producing liquid fuel from wood and other non-food biomass was inaugurated at Freiburg, Saxony. The Choren Industries plant will produce 13,500 tonne/y diesel (known as SunDiesel). Instead of oilseed the plant uses wood or straw as primary material and the BTL (Biomass to Liquid) second generation process. This is based on the Fischer-Tropsch process invented 80 years ago.

NEW TECHNOLOGY Precious metals: nanotechnology provides a new dimension An overview is provided of the development of new products using nanotechnology and precious metals such as gold, silver, platinum, and palladium. Gold nanoparticles now form part of new technologies being developed for the electronics, pollution control, and biomedical sectors. Mintek, the South African mineral research organization, is developing catalysts based on gold nanoparticles. The use of platinum in

both catalytic converters and hydrogen fuel cells is being enhanced via nanotechnology. Mazda researchers report that use of platinum nanoparticles lowered the amount of precious metal needed in a catalytic converter by 70-90%. Silver nanoparticles are being exploited in the biomedical sector because of their antibacterial properties. Nano, Jun 2008, (7), 32-34

A commercial breakthrough in alcohol oxidation Japanese firm Nissan Chemical Industries Ltd is launching ultrahighly active catalysts that employ a catalyst technology designed by a professor from Tohoku University. The new catalysts are 2-aza-adamantane Noxyl (AZADO) derivatives (AZADO), which are claimed to outperform 2,2,6,6-tetraethyl piperidine-N-oxyl (TEMPO) derivatives in terms of activity and yield. AZADO derivatives also have been found to be highly efficient in oxidizing primary and sterically secondary alcohols into the corresponding carbonyl compounds.

Making esters with microwaves Japan’s Chemicrea Inc, with the assistance of the New Energy and Industrial Technology Development Organization and Gifu University, has come up with a new process to produce esters without a catalyst. The new method employs microwaves to progressively remove the water byproduct, increasing the speed and output of the reaction. It also cuts the waste produced by traditional esterifications. In its trials, the firm used the new method to make benzyl bromoacetate. The new method attains an 80% yield in just around one third of the up to 20 hours required by the traditional method. The absence of catalyst and solvent shortens the purification process, while cutting waste. Chemicrea is trying to use the new process for other reactions, including the esterification of glycine with benzyl alcohol. Chemical Engineering (New York), Jul 2008, 115 (7), 16

Propylene or diesel fuel? Just change the controls Shell Global Solutions has developed a new process, called MILOS (Middle Distillates and Lower Olefins Selective process, which allows petroleum refiners to use their existing fluid catalytic crackers (FCCs) for both production of diesel fuel or propylene. The process involves the installation of a second riser to an FCC for making additional propylene, with the existing riser dedicated for regular use or for manufacturing additional light cycle oil. The initial application of MILOS was carried out at the company’s research centre in Houston. Retrofitting an existing FCC will need around $20-70 M, according to Shell Global Solutions.

Shell supports new fuel from sugars A five-year partnership deal has been signed by European petroleum producer Royal Dutch Shell and USAbased Virent Energy Systems to produce a new plant sugar-based fuel that is similar to gasoline. Virent’s BioForming catalytic process turns plant sugars into hydrocarbons using a technology licensed from the Wisconsin Alumni Research Foundation. The hydrocarbon molecules produced during the process closely resemble those produced at a petroleum refinery. Oils and Fats International, Jun 2008, 24 (5), 3

Fulcrum BioEnergy to build one of the first commercial-scale ethanol plants using municipal solid waste Fulcrum BioEnergy Inc is advancing next-generation ethanol production with its plans to build one of the first commercial-scale plants for converting municipal solid waste to ethanol. The plant will process municipal solid waste-household garbage – revolutionizing waste disposal while creating a much needed low-cost, reliable and environmentally clean renewable transportation fuel. When it begins operations in early 2010, the Sierra BioFuels plant is expected to produce about 10.5 M gallon/y of ethanol, and to process nearly 90,000 tonne/y of municipal solid waste that
