AdBlue hits the streets The new European diesel quality regulations have created a new source of demand for urea. The material is being used in a selective catalytic reduction system dubbed AdBlue, which is being introduced all over Europe in 2005. This development may affect about 75% of diesel fuel consumption in Europe, according to the EU. The diesel consumption by heavy vehicles is about 100-110 M tonne/y. If AdBlue will account for 5% of the figure, and urea represents one-third of the mixture, this would translate to an additional demand of more than 1.5 M tonne/y of urea. The overall European manufacturing capacity for AdBlue is placed at 1 M tonne/y, representing around 350,000 tonne/y of urea. An additional 50% increase in consumption may be obtained if a German proposal for its use in all diesel road vehicles is introduced in 2010. Nitrogen and Methanol, Mar/Apr 2005, (274), 24-25

OMV opens the first AdBlue service station in Romania OMV (Austria) opened the first AdBlue service station in Romania in mid Mar 2005. AdBlue is urea solution, which changes harmful nitrogen oxides into nitrogen and water when used as working liquid for diesel-engine utility vehicles. In combination with selective catalytic reduction technology, the liquid reduces the emissions of dieselengine lorry particle emissions by up to 80% and nitrogen oxide emissions by one third. There are AdBlue service stations in Germany, Austria, and the Czech Republic. A total of 67 AdBlue stations are planned to be in various countries by 2007.

freezes at -30° C. Denoxium is more effective than urea in reducing the nitrogen oxide emissions from heavyduty diesel engines, making it compliant with the EU’s new and stricter standards. The product avoids the need to modify car engine settings or delivery systems because it is completely compatible with urea solutions. Automobile and catalyst manufacturers are now field testing Denoxium. Chemical Engineering Progress, Apr 2005, 101 (4), 12

Englehard launches catalyst technology Englehard has developed a catalyst technology that will satisfy Euro IV emission requirements. This is a platinum/palladium diesel oxidation catalyst, which allows 33% of the platinum to be replaced by palladium. This achieves considerable savings on the cost of precious metals. Production should start in May 2005, for two major European car manufacturers. To meet legal requirements, the cars will have three catalyst systems.

Nanoparticulate coated catalysts for sugar conversions There are industrial catalytic processes for both oxidizing and reducing various sugars to make various chemical products. The catalysts are generally platinum metals, but they soon need reactivation. If these catalysts are nanoparticulate and coated with an organic polymer such as polyvinylpyrollidone they retain their catalytic activity much longer. It is surprising that sugars diffuse through these coatings so readily. US 6,894,160, Südzucker AG Mannheim/Ochsenfurt, Germany, 17 May 2005

Follow the money: Oxonica Oxonica, based in Oxford, UK, which has developed a fuel additive, has received $4.83 M in funding through an employee stock purchase. Investors include BASF Venture Capital, NGen Partners, and Generics Asset Management. Oxonica has developed Envirox Fuel Borne Catalyst and Optisol UV Absorber. Oxonica has already agreed to supply Stagecoach Group with the product for its bus fleet and has negotiated a deal with DMX Technology Corp and BASF to supply Envirox into premium branded diesel fuel in the Philippines. Oxonica is due to provide toxicity reports to the EPA in the US in Feb 2005, which is required before US approvals can be granted. Nanotech Report (Forbes/Wolfe), Feb 2005, 4 (2), 7

liquid phase, using a supported nickel catalyst. The catalyst must periodically be regenerated by heating in hydrogen to 200 – 500°. The unexpected feature revealed in this patent is that the rate of heating of the catalyst during regeneration is important.

Auto catalysts containing less platinum metals There is an obvious need to reduce the quantities of platinum metals used in exhaust catalysts. The most critical period in the use of an auto catalyst is at startup when the catalyst is relatively cold: platinum metals are particularly effective under these conditions. A catalyst formulation has now been developed, containing Pr, Ce, Zr, and Y, which is effective with at most 2% of palladium. US 6,893,998, Ford Global Technologies, Dearborn, MI, USA, 17 May 2005

Methanol synthesis This is an improvement on the customary process which uses a copper/zinc oxide catalyst on alumina. The catalyst is prone to poisoning. To avoid this poisoning, an adsorption vessel is fitted before the reactor, operated at a temperature below that of the reactor, to adsorb the poisons. The adsorbent composition is similar to that of the catalyst composition. US 6,894,081, Uhde GmbH, Dortmund, Germany, 17 May 2005
