Due to the adverse effects of SO 2 /NO x on humans and the environment, environmental regulations necessitate the control of their emission. In this study, an activated carbon monolith was synthesized with cobalt oxide (ACM‐Co 3 O 4 ) for the purpose of simultaneous SO 2 /NO x removal from flue gas generated by coal combustion. Average regeneration efficiencies of 92.7 and 94.2 % were obtained for SO 2 and NO x , respectively. The Langmuir model can adequately describe the experimental results of the ACM‐Co 3 O 4 adsorbent in SO 2 and NO x removal. The key regeneration parameters were optimized by using the response surface methodology (RSM). The RSM results revealed that the statistical prediction and experimental results were in agreement.
