Dynea signs NOx agreement
FOCUS now, the company’s issued patents have focused on the use of ammonia gas as the most efficient and costeffective means of reducing NOx emissions through a technology called Selective Catalytic Reduction (SCR), in which the company is the innovator for automotive retrofit applications. The new patent extends the technology to include aqueous ammonia. KleenAir is at the cutting edge of automotive emission reduction technology including SCR, Diesel Particulate Filters, Diesel Oxidizing Catalysts and advanced catalytic technology that significantly reduces nitrogen oxides, carbon monoxide, hydrocarbon and particulates.

Kemira develops new solutions for reducing nitrogen emissions from diesel engine exhaust gas Kemira’s Denoxium products helps to reduce nitrogen emissions from heavy-duty diesel engines to a level compliant with the EU’s new strict limit values and do so more efficiently than has been possible to date. Denoxium products are currently undergoing trials with both automobile and catalyser manufacturers. Kemira is currently investing in Denoxium production at its Oulu plant and is conducting negotiations regarding the production and distribution of this product elsewhere in Europe. Denoxium is a solution of ammonium formate and urea and has a freezing point of –30°C. The product is safe to use and is biodegradable. Press release from: Kemira Oyj, Helsinki, Finland.

Neste, Kemira to collaborate on SCR solution Neste Marketing, Finland, and Kemira GrowHow are to cooperate in the sale and distribution of selective catalytic reduction (SCR) products. These reduce nitrogen oxides to nitrogen and water and are used in diesel engines to meet emission standards, taking effect in 2005-2006, and they may reduce diesel consumption by 5%.

Dynea signs NOx agreement Dynea Chemicals has set up a strategic alliance with GreenChem to produce and market Adblue, a ureabased additive for selected catalytic reduction technology. The technology is used by truck manufacturers to reduce nitrogen oxide and particulate emissions levels to below the new European standards. GreenChem will be responsible for marketing and sales of the additive, whereas Dynea will deal with sourcing and production.
Sweden meant that production of environmental diesel was halted for half a month up to mid-Jan 2005. This in turn led to Sweden having to import European diesel of environmental class III which contains 50 ppm sulfur. Preemraff’s diesel is of environmental class I, with a maximum sulfur content of 10 ppm. The imported diesel, which amounted to 2% of Sweden’s volume of consumption, complied with Swedish environmental requirements but had inferior cold tolerance.

Photocatalytic tantalum nitride
Catalytica Energy Systems’ diesel fuel processor demonstrates improved NOx reduction
Tantalum nitride, Ts3N5, made by reacting tantalum oxide with ammonia, and promoted by platinum, is an efficient photocatalyst for decomposing water using visible light.
Catalytica Energy Systems Inc has successfully completed a 100-hour demonstration of its emissions reduction system for stationary diesel engines. For the duration of the test, the company’s fuel processor-driven NOx adsorber catalyst system demonstrated a greater than 90% reduction in NOx while operating at steady state on a full-scale 8.3 litre diesel generator set rated at 160 kW. The successful outcome of this engine demonstration marks the completion of Phase I of a three-phase development and demonstration program, focusing on the design and performance of Catalytica Energy Systems’ diesel fuel processing technology in combination with a NOx adsorber catalyst for both new stationary diesel engines and retrofit applications. Phase II of the program will include field demonstrations at end-user sites along with further evaluation of the market opportunity and exploring joint development opportunities with prospective partners.

Improved transalkylation catalyst The process involves the transalkylation of C9+ aromatic hydrocarbon mixtures to xylenes. The catalyst is de-aluminated NU-87 containing rhenium. It is superior to mordenite containing rhenium, and to NU-87 containing nickel. US 6,864,400, Institut Français du Pétrol, RueilMalmaison, France, 8 Mar 2005
