摘      要：The DTG curves of a kind of carbon black during TPO tests were found to have multiple peaks with an unusual sharp peak after the main *** tests with different sample loads,oxygen fractions and heating rates were carried out to study the influence of the experimental parameters on the sharp *** results show that the sharp peak is not caused by heat and mass transfer limitations,but by the intrinsic oxidation kinetics of the carbon *** evolution of the specific surface area during the intrinsic kinetic controlled oxidation process was then analyzed using isothermal oxidation at low temperatures which showed that the sharp peak is caused by the increase of the specific surface *** pore structure changes greatly influence the oxidation process when the reaction is controlled by the intrinsic *** there were no heat and mass transfer limitations,the different oxidation processes result in the same specific surface area evolution.
