摘要： PROBLEM TO BE SOLVED: To improve sulfur content collecting performance in an exhaust emission control device in which a sulfur content collecting material is arranged on the upstream side of a nitrogen oxide purification catalyst for collecting and eliminating the sulfur content contained in the exhaust gas, and to reduce a number of times of regeneration processing. SOLUTION: In the exhaust emission control method or the exhaust emission control device for purifying exhaust gas from an internal combustion engine by an exhaust purification catalyst, especially the nitrogen oxide purification catalyst, before the exhaust gas enters the exhaust purification catalyst, the sulfur content contained in the exhaust gas is collected and removed by the sulfur content collecting material composed of complex oxide principally consisting of Sr and Ti or complex oxide containing K in addition to Sr and Ti. In the exhaust emission system of a diesel engine or the like, the sulfur content collecting material consisting of the complex oxide has very high collecting ability of the sulfur content, and thereby, processing for regenerating the sulfur content collecting material can be dispensed with or a frequency of its regeneration processing can be lowered, and deterioration in fuel economy and in activity of the exhaust purification catalyst following regeneration processing can be reduced. Further, sulfur poisoning of the nitrogen oxide purification catalyst can be prevented in the exhaust emission control device. COPYRIGHT: (C)2009,JPO&INPIT
摘要翻译：解决的问题：为了提高废气排放控制装置中的硫含量收集性能，其中硫含量收集材料设置在氮氧化物净化催化剂的上游侧，用于收集和消除废气中所含的硫含量气体，并减少再生处理次数。解决方案：在废气排放控制方法或废气排放控制装置中，在排气进入排气净化催化剂之前，通过排气净化催化剂，特别是氮氧化物净化催化剂净化来自内燃机的废气的废气排放控制装置，通过由Sr和Ti组成的复合氧化物或除Sr和Ti之外含有K的复合氧化物构成的硫含量收集材料收集和除去废气中含有的硫含量。在柴油发动机等的废气排放系统中，由复合氧化物构成的硫含量收集材料具有非常高的硫含量收集能力，因此可以省略用于再生硫含量收集材料的处理或可以降低其再生处理的频率，可以降低再生处理后的燃料经济性和排气净化催化剂的活性。此外，在废气排放控制装置中可以防止氮氧化物净化催化剂的硫中毒。版权所有（C）2009，JPO＆INPIT

Performance of the sulfur content-absorbing material can be further improved by combination with an oxidation catalyst. COPYRIGHT: (C)2008,JPO&INPIT
