摘要： Methods, systems, and computer readable media are disclosed for providing a maintenance recommendation for a catalyst based on a trained machine learning model. The method includes: extract training data comprising one or more parameters from each catalyst of a plurality of catalysts: classify the training data in accordance with at least one catalyst feature at least one of the contaminations of the catalyst: determine a feature vector from the classified training data based on the one or more parameters extracted from catalyst of the plurality of catalysts, generate a performance baseline curve from the training data in accordance with the destruction removal efficiency (DRE) of a gas; and provide based on the trained machine learning model a maintenance recommendation for the catalyst.

摘要： The present disclosure provides catalyst compositions capable of reducing nitrogen oxide (NOx) emissions in engine exhaust, catalyst articles coated with such compositions, and processes for preparing such catalyst compositions and articles. The catalyst compositions include metal ion-exchanged zeolites useful for selective catalytic reduction (SCR) of NOx. Further provided is an exhaust gas treatment system including such catalytic articles, and methods for reducing NOx in an exhaust gas stream using such catalytic articles.
