*3.2. Polypropylene (PP)*

Figure 9 shows the deviations between measured and modeled results for the test runs with PP. PP cracks at lower temperatures than the other plastic types studied in this work [8], which is confirmed by yields lower than 50% for the "Residue" fraction, except for one test run. Furthermore, the share of the "Residue" fraction is overpredicted from the model, contrariwise the share of the "Light Liquids" fraction is underpredicted.

**Figure 9.** Deviation of the modeled and measured values of the test runs with carrier fluid and PP. "MAE" is the mean absolute error of the optimization of 0.42 <sup>×</sup> <sup>10</sup>−<sup>2</sup> kg/kg. The dashed lines show the 10% deviation.
