The influences of four heating rates on the combustion and pyrolysis behavior in the N2 and air atmosphere were investigated by the Fourier transform infrared spectrometry (FTIR) and thermogravimetric (TG) analysis. the distributed activation energy model (DEAM) and Flynn-Wall-Ozawa (FWO) were used to estimate Ea and A, ΔH, ΔG and ΔS. Experimental results showed that the similar thermal behavior emerged, but the temperatures in the air and N2 atmospheres representing the end of the reaction were about 500 °C and 550 °C, respectively. The results of FTIR showed the peak positions were basically the same, but the concentrations of aromatics, aldehydes and ketones produced by pyrolysis in the N2 atmosphere were higher. When the heating rate was 20 K/min, the comprehensive combustion parameters were 56.442 and 6.871 × 10−7%2/(min2• K3) in the air and N2 atmospheres, respectively, indicating that the peanut shells had great potential to become bioenergy.

The effects of ozone concentration, NaOH concentration, type and concentration of additives, initial pH, temperature, and NO and SO 2 concentration on simultaneous removal of NO and SO 2 were studied through ozone oxidation combined with wet absorption. Results indicated that ozone concentration and the type and concentration of additives had the most significant effect on NO removal. The optimal ozone concentration was 250 ppm (NO/NO 2 = 1), and the best additive was KMnO 4 . The removal efficiency of NO x was as high as 97.86% when NO/NO 2 = 1, and the concentration of KMnO 4 was 0.025 mol/L. Considering economic and other factors, the KMnO 4 concentration was selected to be 0.006 mol/ L. At this time, the removal efficiencies of NO x and SO 2 were 81.35 and 100%, respectively. This method has potential application prospects for simultaneous removal of SO 2 and NO in the industrial flue gas.
