KAS Method

Figure 5 shows a plot of ln *bT*2*α* against 1000 *Tα* at different heating rates 5 K/min, 10 K/min and 15 K/min at the same conversion for varying conversions from 5% to 50%, during which active pyrolysis takes in *S. bigelovii* and *P. dactylifera*. The calculated activation energy, *E* (kJ/mol), and the pre-exponential factor, *A* (1/min), were 147.3 kJ/mol and 3.57 × 10<sup>14</sup> (1/min) for *S. bigelovii*, respectively, and 201.4 kJ/mol and 8.54 × 10<sup>31</sup> (1/min) for *P. dactylifera*, respectively.
