摘要

The present invention relates to a method for preparing activated carbon from needle coke through two-level steam activation and, more specifically, to a method for preparing mesoporous activated carbon having high specific surface area by generating pores having the size of 2 nm or more from needle coke through first steam activation and expanding the pores through second steam activation by coating and impregnating a low molecular material in the pores. According to the two-level steam activation method of the present invention, mesoporous activated carbon having high specific surface area of 1,134 m^2/g and having more than 70% mesoporous volume can be prepared from needle coke.
