Abstract

Spontaneous ignition characteristics were observed by performing experiments for granulated activated carbon at constant ambient temperature in an oven. As the results of the experiments, the critical spontaneous ignition temperature of sample for large, intermediate and small vessels was 158.5$^{\circ}C$ , 165.5$^{\circ}C$ and 174.5$^{\circ}C$, respectively. It was found that the critical spontaneous ignition temperature decreased and the ignition induction time increased as the sample vessel size increased. Apparent activation energy of the sample calculated from the Frank= kamenetskii's thermal ignition theory was 17.81*10$^3$J/mol.
