Preparing of Bamboo Charcoal with High Temperature Carbonization

High temperature carbonization process was used to prepare bamboo charcoal.The effect of temperature,holding time and temperature rate on the adsorptive properties of bamboo charcoal was discussed.The pore structures of the bamboo charcoal were characterized by N2-adsorption isotherms.It was found that as temperature and holding time went up,the adsorption value of methylene blue and iodine of the samples increased,as temperature rate enhanced,the graphitization degree of carbon precursor increased,and the pore structure decreased.High-temperature carbonization could be obtained microporous,mesoporous,macroporous more developed bamboo charcoal.Under optimized experimental condition,the adsorption value of methylene blue and iodine of the samples were 280 mg·g-1 and 947.3 mg·g-1,respectively.
