“…The activation energy for the oxidation of soot is calculated by the differential method. First, the conversion rate (α) of the sample is defined as , where m 0 , m ∞ , m , T , and t represent the mass of sample at the beginning of the reaction, the mass at the end of the reaction, the sample mass at T ( t ), the reaction temperature, and time, respectively.…”

Diesel particulate filter is an effective device to reduce diesel particulate emission. The particles in diesel particulate filter are usually affected by the aging of high-temperature exhaust gas before the regeneration process. In order to investigate the effect of aging conditions on the soot oxidation process, the effect of aging temperature and aging time on the oxidation process of carbon black (Printex-U, PU) and the PU/catalyst/ash mixture are studied by thermogravimetric analysis. The aging PU particles have lower starting temperature, peaking temperature, ending temperature, and activation energy. Compared with the particles without aging, the PU particles with a 400 °C aging temperature and 20 h aging time are able to reduce the activation energy from 191.2 to 158 kJ/mol. Low aging temperatures (200–300 °C) and the catalyst have a certain synergistic effect on the improvement of PU oxidation activity. The PU/CeO2 mixture with a 300 °C aging temperature and 20 h aging time decreases the activation energy from 178.4 to the lowest 113.6 kJ/mol. The addition of CaSO4 in PU particles cannot stop the improvement of its oxidation activity by aging, but it reduces the effect of aging. This work is helpful to reveal the mechanism of aging on PU and the PU/catalyst/ash mixture in air environment.

“…A mass sample in the range of 10–15 mg was placed in an Al 2 O 3 crucible and progressively heated from 20 to 670 °C at four heating rates, 5, 10, 15, and 20 °C/min. The heating rates were strategically chosen to cover a wide range of pyrolysis processes available in the literature [ 27 , 28 , 29 , 30 , 31 ]. The conversion (1 – instantaneous mass fraction) and pyrolysis rate (a derivative of conversion against time) could be determined from the experimental data.…”

In the present study, the waste polyethylene (PE) pyrolysis under different non-isothermal conditions was investigated to estimate the optimal conversions and pyrolysis rates. The pyrolysis study was carried out using Thermogravimetry (TG) of the virgin and the waste PE under different heating rates of 5, 10, 15 and 20 C/min. The TG experiments indicated that the virgin and the waste PE pyrolysis processes mainly underwent in the temperature range of 390-510 C. Subsequently, the adaptive neural fuzzy model was adopted to predict the conversions and the pyrolysis rates of the virgin and the waste PE. The optimal operating conditions in different temperature ranges were optimized by the simulated annealing algorithm (SA). Moreover, the R-squared values of the virgin PE conversions (~1) and pyrolysis rates (> 0.999), and the waste PE conversions (~1) and pyrolysis rates (> 0.999) revealed the high accuracy of the adaptive neural fuzzy model predicted results.

“…3). The liquid oil fraction increases gradually with an increase in the temperature (350-500℃), and a further rise in temperature decreases the oil yield [47,51,52]. At very high temperatures, the retention time was short of converting wax into bio-oil molecules [47,51,52].…”
