Abstract: The study on columnar activated coke (AC) modified by H2O2 and HNO3 (HAC) has shown that, compared to original sample AC, the BET surface area and micro-pore area of HAC increased 162.8 m2/g and 143.8 m2/g respectively. Three types of low temperature selective catalytic reduction (SCR) catalysts were developed by loading on HAC with nano-V2O5, nano-Fe2O3 and nano-V2O5/Fe2O3, respectively. All those catalysts samples were characterised by BET area and pore structure analysis, XRD, TEM and SEM. Under the same conditions: 500 ppm NO, 500 ppm NH3, 5% O2, N2 balance, 6,000 L/(Kg • h), 200°C, an investigation has been made over the NO removal performances of some samples and the results showed that the denitration rates of AC, HAC, V2O5/AC, Fe2O3/AC and V-Fe/AC are 14.73%, 51.67%, 59.25%, 64.93% and 67.85%, respectively. The best denitration performance was achieved by V-Fe/AC catalyst, which represents an increase of 53.12% compared to original AC. [Received: September 22, 2014; Accepted: May 22, 2015]
