With the advantages of high efficiency, recycling useful components, simple equipment, simple operation and easy to automate, the approach of low temperature adsorption-high temperature (or decompression) desorption-decomposition (reduction) is usually adopted to deal with large space velocity and low concentrations of NOx gases to eliminate NOx. In this study, various support materials and active components for adsorbing NOx were studied, and the effects of textural properties, surface acidity of the absor...
