## 4 Results  
The results obtained in the laboratory analysis are presented in Tables 4-6 for the dried samples, samples processed at 200 \({}^{\circ}\)C, and samples processed at 300 \({}^{\circ}\)C, respectively. All analyses were conducted in triplicate, and average values and standard deviation for all tests and calculations were determined. \begin{table}

Table 4: Results obtained in the analysis conducted with dried samples. FC, fixed carbon; HHV, higher heating value. Table 4 presents the results obtained for samples after drying. As can be seen in the results of elementary analysis, the average values obtained for carbon, hydrogen, nitrogen, and oxygen were 47.40%, 6.59%, 0.11%, and 45.99%, with standard deviations of 0.58, 0.39, 0.02, and 0.53, respectively. Thermogravimetric analysis gave mean values for fixed carbon, volatiles, ash, and moisture of 16.38%, 81.25%, 1.36%, and 3.31%, with standard deviations of 0.13, 1.30, 0.10, and 0.51, respectively. The HHV, calculated using Equation (2), presented an average value of 18.17 MJ-kg-1 with a standard deviation of 0.55. Table 5 presents the results obtained for the samples after thermal treatment at 200 \({}^{\circ}\)C. As can be seen in the results of elementary analysis, average values obtained for carbon, hydrogen, nitrogen, and oxygen were 53.16%, 6.44%, 0.12%, and 40.28%, with standard deviations of 2.42, 0.19, 0.01, and 2.32, respectively. Thermogravimetric analysis gave mean values for fixed carbon, volatiles, ash, and moisture of 20.79%, 77.74%, 1.48%, and 1.03%, with standard deviations of 0.60, 1.35, 0.38, and 0.22, respectively. The HHV, calculated using Equation (2), presented an average value of 20.75 MJ-kg-1 \begin{table}
