GOALI: High Stability Copper Zeolites for Lean NOx Automotive Catalysts

建议标题：GALI：用于稀薄NOx汽车催化剂的高稳定性铜沸石建议编号：CTS-9980396主要研究员：杰弗里·普里斯研究所：路易斯安那州立大学和农业与机械学院本建议的目标是开发性能增强的稀薄NOx发动机金属离子交换沸石催化系统。这些类型的发动机的排放控制受到了缺乏耐用的活性催化剂的影响，这种催化剂可以在氧化性废气中运行。这个项目是路易斯安那州立大学和通用汽车公司的合作项目。大部分沸石合成将在路易斯安那州立大学进行，GM将测试反应活性并研究反应动力学。更好地了解用于稳定的SUZ-4型沸石的制备方法。研究最广泛、前景最好的NOx催化体系使用的是含铝沸石(MFI)，其中离子交换金属沉积在沸石孔内的酸性中心。在前期工作中，载铜沸石具有较高的NOx分解活性。这项工作将继续下去，并将进行动力学研究。如果成功，该项目将有助于开发一种催化剂，该催化剂将解决大气污染的主要来源之一--汽车排放的氮氧化物。

AbstractProposal Title: GOALI: High Stability Copper Zeolites for Lean NOx Automotive CatalystsProposal Number: CTS-9980396Principal Investigator: Geoffrey PriceInstitution: Louisiana State University and Agricultural and Mechanical CollegeThe objective of this proposal is to develop metal ion exchange zeolite catalytic systems with enhanced performance for lean NOx engines. Emissions control for these types of engines suffer from the lack of a durable, active catalyst, which can operate in oxidizing exhaust. This project is a collaboration between LSU and General Motors. Most of the zeolite synthesis will be carried out at LSU, and GM will test the reactivity and investigate the reaction kinetics. Better understanding of methods of making SUZ-4 type zeolites for stability will be pursued. The most widely studied and promising NOx catalytic system uses an aluminum containing zeolite (MFI) with an ion-exchanged metal deposited on the acid sites within the zeolite pores. In preliminary work copper-loaded zeolite yielded relatively high activity for NOx decomposition. This work will be continued, and kinetic studies will be carried out. If successful, this project will assist in the development of a catalyst that will solve one of the main sources of atmospheric pollution, the emission of NOx by automotive sources.
