| Abstract: | A Cu-SAPO-34/cordierite catalyst was prepared by in situ hydrothermal synthesis.The morphology and structure of the Cu-SAPO-34/cordierite samples were characterized by X-ray diffraction,scanning electron microscopy,and physical adsorption-desorption analyzer.The removal of NOx from simulated diesel vehicle exhaust gas was carried out using a fixed-bed reactor.The effects of C3H8,O2 concentrations,and water vapor on the activity of the catalyst were studied.The results indicate that the Cu-SAPO-34 coatings o... |
