Abstract
The aggressive acid treatment creates a wealth of oxygen-containing functional groups (-OH, C=O, C-O) on the surface of an adsorbent and acts as binding sites for catalyst support therefore, in this study, the surface of monolith (ACM) was oxidized via the acid modification and high temperature activation. Various types of catalysts from the precursors of cerium nitrate (CeO2 /ACM), copper nitrate (CuO/ACM) and cobalt nitrate (Co3 O4 /ACM) using the deposition precipitation synthesis method. The catalyst activity tests were investigated in a fixed bed reactor by passing a stream of flue gas generated by burning coal. The breakthrough study of SO2 /NOx and the experimental results showed that for CeO2 /ACM catalyst the adsorption capacity of SO2 was 24.3 and 18.5 mg/g for NOx and for CuO/ACM catalyst they were 27.0 and 32.8mg/g and for Co3 O4 /ACM catalyst, values obtained were 10.6 and 49.7mg/g. FTIR, BET and FESEM analysis were performed. This investigation depicts the development of highly efficient adsorbent for flue gas treatment.
