NaOH활성화에 의한 커피활성탄의 제조
Preparation of activated coffee char by NaOH activation
Activated coffee char was prepared from coffee waste by chemical activation with Sodium Hydroxide. In this study, the following processes were carried out : roasting step, carbonization step and chemical activation or Physical activation step. N2-BET surface areas and total pore volume of activated coffee char produced by chemical activation using NaOH were measured as about 1265∼2300m2/g and 0.67∼1.14cm3/g, respectively.
