- Abstract
The kinetics of oxidation of naphthalene and a heavy oil residue (upon vacuum distillation) by oxygen dissolved in supercritical water is studied in a wide range of temperatures (663 K ≤ T ≤ 1075 K) and pressures (31 MPa ≤ P ≤ 67 MPa). It is established that the oxidation process exhibits an explosive (blow-up) character. The kinetic constants characterizing the thermal explosion are determined. For naphthalene, the heat evolution rate during the explosive oxidation obeys the law W[sub N] = 10[sup 13.10±0.30]exp((170.4 ± 1.0 kJ/mol)/RT) × [C[sub 10]H[sub 8]][sup 0.46 ± 0.01][O[sub 2]][sup 0.63 ± 0.01][H[sub 2]O][sup 1.66 ± 0.03] kJ/(1 s).
