The potential for using a coconut shell catalyst for the selective catalytic reduction of NO_xgases

Abstract

Selective Catalytic Reduction (SCR) is a promising technique in mitigating the drawbacks of combustion system. This study investigated the potential of using coconut shell activated carbon (CSAC), an abundant and inexpensive resource, as an SCR catalyst support for sustainable energy generation. Local CSAC was physically treated by co-impregnating with Copper (Cu) and Manganese (Mn) oxides. The modified samples were then calcined under low temperature. Properties of all three types of samples were then characterized and analysed using Temperature-Programmed Reduction (TPR), X-Ray Fluorescence (XRF) and Fourier Transform Infrared (FT-IR). Results showed that CSAC can be an effective SCR catalyst to obtain higher conversion of NOx gases into non-toxic gas.
