Effect of V2O5/WO3-TiO2 catalyst preparation method on NOx removal from diesel exhaust

High-efficiency reduction of NOx emission from diesel exhaust using a CeWOx catalyst

Simultaneous NOx and Particulate Matter Removal from Diesel Exhaust by Hierarchical Fe-Doped Ce–Zr Oxide

Particulate matter and NO x emissions from diesel exhaust remains one of the most pressing environmental problems. We explore the use of hierarchically ordered mixed Fe-Ce-Zr oxides for the simultaneous capture and oxidation of soot and reduction of NO x by ammonia in a single step. The optimized material can effectively trap the model soot particles in its open macroporous structure and oxidiz...

Online NOx Removal from Stationary Diesel Engine Exhaust by Barrier Discharge Plasma

This paper reports plasma treatment of a 5 HP stationary diesel engine exhaust at full flow-rate (approximately 387 l/min) energized by power frequency AC. Glass and Chlorinated Polyvinyl Chloride (CPVC) tubes were used as the dielectric barriers. Significant removal of NO and NOx has been achieved with barrier discharge plasma. The reactors were specially fabricated to facilitate high flow and...

Recent Developments in Plasma De-NOx and PM (Particulate Matter) Removal Technologies from Diesel Exhaust Gases

Industrialization of plasma De-NOx system needs combination of various technologies technologies. This article introduces these many technologies and discusses the technical problems and their solutions. Such technologies include system design, efficiency requirements, component design method, plasma chemical reactions, optimization of process, scheme of the system, modification of discharge mo...

Treatment of NOx from Diesel Engine Exhaust by Dielectric Barrier Discharge Method

This paper reports improved performance of discharge plasma in filtered engine exhaust treatment. Our paper deals about the removal of NOX emissions from the diesel exhaust by electric discharge plasma. For the treatment of diesel exhaust a new type of reactor referred to as cross-flow dielectric barrier discharge reactor has been used, where the gas flow is perpendicular to the corona electrod...
