Simultaneous Reduction of NOX and CO Harmful Gases According to the Promoters and Support Types of H2-SCR Catalyst
The purpose of this study is to simultaneously reduce NOX and CO harmful gases according to the promoters and support types of the H2-SCR. The 0.5Pt-2CeO2-5Ru/TiO2 catalyst loaded with 7 wt% Ru showed a lower NOX conversion rate compared to than the 0.5Pt-2CeO2/TiO2 (STD), but the window shifted to the right, and it showed NOX reduction performance of up to 30% at 175 °C. When Zr was loaded, de- NOX performance was not improved at the temperature of 200 °C starting from a low catalyst temperature of 75 °C. With in the influence of the support types, the 0.5Pt-2CeO2/TiO2 H2-SCR catalyst showed the highest NOX conversion rate below 125 °C, and the low-temperature activity of NOX was higher than that of the three zeolite-loaded H2-SCR catalysts. Low temperature activity was improved because the TiO2 has excellent reducing and oxidizing ability. Among the three zeolites, the CO reduction performance of the 0.5Pt-2CeO2/Zeolite (1) catalyst with high Al content was the lowest.
期刊介绍：
The International Journal of Automotive Technology has as its objective the publication and dissemination of original research in all fields of AUTOMOTIVE TECHNOLOGY, SCIENCE and ENGINEERING. It fosters thus the exchange of ideas among researchers in different parts of the world and also among researchers who emphasize different aspects of the foundations and applications of the field.
Standing as it does at the cross-roads of Physics, Chemistry, Mechanics, Engineering Design and Materials Sciences, AUTOMOTIVE TECHNOLOGY is experiencing considerable growth as a result of recent technological advances. The Journal, by providing an international medium of communication, is encouraging this growth and is encompassing all aspects of the field from thermal engineering, flow analysis, structural analysis, modal analysis, control, vehicular electronics, mechatronis, electro-mechanical engineering, optimum design methods, ITS, and recycling. Interest extends from the basic science to technology applications with analytical, experimental and numerical studies.
The emphasis is placed on contributions that appear to be of permanent interest to research workers and engineers in the field. If furthering knowledge in the area of principal concern of the Journal, papers of primary interest to the innovative disciplines of AUTOMOTIVE TECHNOLOGY, SCIENCE and ENGINEERING may be published. Papers that are merely illustrations of established principles and procedures, even though possibly containing new numerical or experimental data, will generally not be published.
When outstanding advances are made in existing areas or when new areas have been developed to a definitive stage, special review articles will be considered by the editors.
No length limitations for contributions are set, but only concisely written papers are published. Brief articles are considered on the basis of technical merit.
