A series of spherical activated carbons(SACs)with different pore structures were prepared from chloromethylated polydivinylbenzene by ZnCl2 activation.The effects of activation temperature and retention time on the yield and textural properties of the resulting SACs were studied.All the SACs are generated with high yield of above 65% and exhibit relatively high mesopore fraction(me%) of 35.7%-43.6% compared with conventional activated carbons.The sample zlc28 prepared at 800℃ for 2 h has the largest BET surface area of 891m2g-1 and pore volume of 0.489 cm3g-1,SEM and XRD analyses of zlc28 verify the presence of developed porous structure composed of disordered micrographite stacking with large amounts of interspaces in the order of nanometers.
