Download or read book Plasma Regenerated Particulate Trap and NO sub x Reduction System written by and published by . This book was released on 2000 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A non-catalytic two-stage process for removal of NO.sub.x and particulates from engine exhaust comprises a first stage that plasma converts NO to NO.sub. 2 in the presence of O.sub. 2 and hydrocarbons, and a second stage, which preferably occurs simultaneously with the first stage, that converts NO.sub. 2 and carbon soot particles to respective environmentally benign gases that include N.sub. 2 and CO.sub. 2. By preconverting NO to NO.sub. 2 in the first stage, the efficiency of the second stage for NO.sub.x reduction is enhanced while carbon soot from trapped particulates is simultaneously converted to CO.sub. 2 when reacting with the NO.sub. 2 (that converts to N.sub. 2). For example, an internal combustion engine exhaust is connected by a pipe to a chamber where carbon-containing particulates are electrostatically trapped or filtered and a non-thermal plasma converts NO to NO.sub. 2 in the presence of O.sub. 2 and hydrocarbons. Volatile hydrocarbons (C.sub.x H.sub.y) from the trapped particulates are oxidized in the plasma and the remaining soot from the particulates reacts with the NO.sub. 2 to convert NO.sub. 2 to N.sub. 2, and the soot to CO.sub. 2. The nitrogen exhaust components remain in the gas phase throughout the process, with no accompanying adsorption.

This book was released on 2001-09-17 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the most recent report of the National Research Council's Standing Committee to Review the Research Program of the Partnership for a New Generation of Vehicles (PNGV), which has conducted annual reviews of the PNGV program since it was established in late 1993. The PNGV is a cooperative R&D program between the federal government and the United States Council for Automotive Research (USCAR, whose members are DaimlerChrysler, Ford Motor Company, and General Motors) to develop technologies for a new generation of automobiles with up to three times the fuel economy of a 1993 midsize automobile. The reports review major technology development areas (four-stroke direct-injection engines, fuel cells, energy storage, electronic/electrical systems, and structural materials); the overall adequacy of R&D efforts; the systems analysis effort and how it guides decisions on R&D; the progress toward long-range component and system-level cost and performance goals; and efforts in vehicle emissions and advanced materials research and how results target goals. Unlike previous reports, the Seventh Report comments on the goals of the program, since the automotive market and U.S. emission standards have changed significantly since the program was initiated.

Download or read book Plasma assisted Catalytic Storage Reduction System written by and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A two-stage method for NO.sub.x reduction in an oxygen-rich engine exhaust comprises a plasma oxidative stage and a storage reduction stage. The first stage employs a non-thermal plasma treatment of NO.sub.x gases in an oxygen-rich exhaust and is intended to convert NO to NO.sub. 2 in the presence of O.sub. 2 and hydrocarbons. The second stage employs a lean NO.sub.x trap to convert such NO.sub. 2 to environmentally benign gases that include N.sub. 2, CO.sub. 2, and H.sub. 2 O. By preconverting NO to NO.sub. 2 in the first stage with a plasma, the efficiency of the second stage for NO.sub.x reduction is enhanced. For example, an internal combustion engine exhaust is connected by a pipe to a first chamber in which a non-thermal plasma converts NO to NO.sub. 2 in the presence of O.sub. 2 and hydrocarbons, such as propene. A flow of such hydrocarbons (C.sub.x H.sub.y) is input from usually a second pipe into at least a portion of the first chamber. The NO.sub. 2 from the plasma treatment proceeds to a storage reduction catalyst (lean NO.sub.x trap) that converts NO.sub. 2 to N.sub. 2, CO.sub. 2, and H.sub. 2 O, and includes a nitrate-forming catalytic site. The hydrocarbons and NO.sub.x are simultaneously reduced while passing through the lean-NO.sub.x trap catalyst. The method allows for enhanced NO.sub.x reduction in vehicular engine exhausts, particularly those having relatively high sulfur contents.

Download or read book Plasma Aftertreatment for Simultaneous Control of NOx and Particulates written by and published by . This book was released on 1999 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Plasma reactors can be operated as a particulate trap or as a NO(subscript x) converter. The soluble organic fraction (SOF) of the trapped particulates can be utilized for the oxidation of NO to NO2. The NO2 can then be used to non-thermally oxidize the carbon fraction of the particulates. This paper examines the energy density required for oxidation of the SOF hydrocarbons and the fate of NO2 during the oxidation of the particulate carbon. The energy density required for complete oxidation of the SOF hydrocarbons is shown to be unacceptably large. The reaction of NO2 with carbon is shown to lead mainly to backconversion of NO2 to NO. These results suggest that the use of a catalyst in combination with the plasma will be required to efficiently reduce the NO(subscript x) and oxidize the SOF hydrocarbons.

Book excerpt: Emission abatement system. The system includes a source of emissions and a catalyst for receiving the emissions. Suitable catalysts are absorber catalysts and selective catalytic reduction catalysts. A plasma fuel converter generates a reducing gas from a fuel source and is connected to deliver the reducing gas into contact with the absorber catalyst for regenerating the catalyst. A preferred reducing gas is a hydrogen rich gas and a preferred plasma fuel converter is a plasmatron. It is also preferred that the absorber catalyst be adapted for absorbing NO.sub.x.
