Abstract: The sulfur-doped microporous carbon(SMC) was prepared by using s-containing poly(sodium 4-styrenesulfonate) as the precursor,and zinc chloride(ZnCl2)as the activating agent.The influence of activation time,activation temperature and activating agent concentration on the carbon property were investigated.The samples were most of pores which smaller than 2.0nm,its specific surface area was from 625m2/g to 880m2/g.The optimized parameters were at ZnCl2 concentration of 1.00mol/L,activation time of 60min and activation temperature of 800℃.CSZ3 showed a high adsorption capacity of carbon dioxide (CO2) and methane (CH4) at high pressure.
