Diesel Exhaust Treatment Using Catalysts/Zeolites

Non-thermal Plasma Treatment of Automotive Exhaust Gases

Treatment of NOx in diesel engine exhaust represents a big opportunity for the environmental application of low-temperature plasmas. In this paper NOx conversion to N2 was investigated by Plasma/Catalyst System Catalytic activity was enhanced by the assistance of plasma ,and the plasma/Catalyst system showed higher NOx conversion. It is shown that the plasma by itself cannot chemically reduce N...

Diesel Exhaust After-Treatment by Silicon Carbide Fiber Filter

To reduce particulate matter (PM) in diesel exhaust gas, a diesel particulate filter (DPF) has been developed. The thermal durability of existing platinum catalyst-supported DPFs is inadequate. We are focusing on a non-catalytic after-treatment of silicon carbide (SiC) fibers with highly thermal durability. In this study, we simulated the processes of soot deposition and oxidation. Results show...

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...
