Окислительный катализ, помимо нейтрализации СО и НС, обеспечивает необходимую эффективность и работоспособность дизельных фильт ров улавливания дисперсных частиц и систем селективной очистки оксидов азота. Кроме того, окислительные нейтрализаторы могут быть инструментом обезвреживания выбросов метана и некоторых ненормируемых, но весьма опасных полициклических и частично окисленных углеводородов. Есть и слабо изученные теоретические вопросы окислительного катализа, связанные со взаимным влиянием токсичных компонентов, содержащихся в отработавших газах дизелей.</p><p>Цель исследования – уточнение роли окислительного катализа в общей проблеме нейтрализации токсичных выбросов дизелей, разработка и испытания катализаторов и нейтрализаторов для обезвреживания токсичных продуктов сгорания двигателей, работающих на природном газе.</p><p>Методология и методы. Исследование катализаторов в проточных условиях с привлечением современных методов газового анализа, ИК-спектроскопия, моторные испытания разработанных нейтрализаторов.</p><p>Результаты и научная новизна. Показана роль окислительного катализа в решении общих проблем нейтрализации вредных выбросов дизелей, включая как прямую нейтрализацию токсичных соединений, так и обеспечивающие функции. Разработаны катализаторы повышенной эффективности и серия нейтрализаторов для газовых двигателей. Предложены оригинальные методы повышения устойчивости окислительных катализаторов к оксидам серы. Практическая значимость. Разработанные катализаторы и конструкции нейтрализаторов рекомендованы к внедрению на газовых двигателях КАМАЗ-820.52-260 и Cummins 250 и 280.</p></abstract><trans-abstract xml:lang="en"><p>Introduction (problem statement and relevance). The oxidation catalysis provides the necessary efficiency and performance of diesel filters for trapping dispersed particles and systems for selective treatment of nitrogen oxides. In addition, oxidation catalysts can be a tool for neutralizing emissions of methane and some non-regulated but very hazardous polycyclic and partially oxidized hydrocarbons. There are also poorly studied theoretical issues of oxidation catalysis associated with mutual influence of toxic components contained in exhaust gases of diesel engines.</p><p>The purpose of the study is to clarify the oxidation catalysis role in the general problem of after-treatment of toxic emissions of diesel engines, development and testing of catalysts and converters for neutralization of toxic combustion products of engines powered by natural gas.</p><p>Methodology and research methods. Research into the catalysts under flow conditions using modern methods of gas analysis, IR spectroscopy, engine tests of the developed catalytic converters.</p><p>Scientific novelty and results. The paper shows the role of oxidation catalysis in solving the common problems of after-treatment of hazardous emissions of diesel engines including both direct after-treatment of toxic compounds and supporting functions. Catalysts of higher efficiency and a series of converters for gas engines have been developed. Innovative methods to increase the resistance of oxidation catalysts to sulfur oxides have been proposed.</p><p>Practical significance. The developed catalysts and converter designs are recommended for implementation in KAMAZ-820.52-260 and Cummins 250 and 280 gas engines.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>окислительный катализ</kwd><kwd>газовые двигатели</kwd><kwd>метан</kwd><kwd>оксиды серы</kwd><kwd>дезактивация катализаторов</kwd><kwd>системы нейтрализации</kwd><kwd>отработавшие газы</kwd><kwd>дизели</kwd></kwd-group><kwd-group xml:lang="en"><kwd>oxidation catalysis</kwd><kwd>gas engines</kwd><kwd>methane</kwd><kwd>sulfur oxides</kwd><kwd>catalyst deactivation</kwd><kwd>after-treatment systems</kwd><kwd>exhaust gases</kwd><kwd>diesel engines</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Тер-Мкртичьян Г.Г., Демидов А.А., Старков Е.Е.
