Abstract

The selective catalytic reduction (SCR) of NOx with NH3 has been investigated with coal ash. Coal samples from different regions of the People Republic of China are taken and processed to be used as the SCR catalysts. The influences of different coal ash catalysts, as well as the influences of calcination temperatures on the NOx conversion of catalysts, are analyzed. The methods of XRF, XRD, and BET are used to characterize the materials. It is found that the calcined sample at 800 °C with Ca: Fe: Al: Si ratio of 0.051: 0.123: 0.511: 1, exhibited good NH3-SCR activity in a broad temperature range of 200–500 °C. As well, the influences of [NH3]/[NO] molar ratio and oxygen concentration on the SCR activity are also studied.
