Abstract: Steam activation was used to prepare activated carbon from Myrica rubra(Chinese bayberry) stones. An orthogonal test with three factors and three levels was set:(1) activation temperature of 850,900 and 950 ℃;(2) activation time of 1.5,20 and 2.5 h;(3) steam comsumption of 4,5 and 6 mLg-1. And adsorption capabilities of M. rubra stone carbon for benzene,formaldehyde,ammonia and chloroform were measured. The data were analyzed by ANOVA. The results showed that optimal conditions for activation were:temperature of 950 C,time of 1.5 h,and steam consumption of 5 - 6 mLg-1 of M. rubra stone carbon. With these optimized conditions activated carbon from prepared bayberry stones had a 34.2% yield with iodine adsorption of 1 167.2 mgg-1 and methylene blue of 132.0 mgg-1. For activated carbon from M. rubra stones,activation temperature significantly(P<0.05) decrease yield and increase adsorption abilities,whereas activation time only significantly decreased (P<0.05) yield. M. rubra stone carbon also adsorbed toxic gases with formaldehyde>chloroform>benzene>ammonia.[Ch,2 fig. 5 tab. 7 ref.]
