| Abstract: | Methane gas-liquid oxidation was carried out in a high-pressure reactor with oleum as solvent and iodine as catalyst at 443-473 K and methane pressure of 3.0 MPa. By fitting the experimental data, the intrinsic kinetic reaction rate equation was obtained to be -rA=kCA, in which the reaction rate constants at 443 K, 453 K, 463 K and 473 K are 0.0271, 0.0284, 0.0344 and 0.0391,respectively;the activation energy E is 22.49 kJ·mol-1;and the frequency factor k0 is 11.75 min-1. |
