摘要/Abstract

摘要： A novel two-step procedure was used to manufacture microporous activated carbon from raw coconut shell. In this process, the raw coconut shell was (1) heated in an inert environment to temperatures be-
tween 450℃ and 850℃, and reacted with oxygen ( ＝1.1－5.3kPa) for some time, and (2) heated again in in-
ert environment to activation temperature(850℃) to produce an activated carbon. Activated carbons with specific surface area greater than 700m2•g－1 were manufactured with a yield between 24% and 28%. It was shown that the carbon had a narrow distribution of pore size, possibly less than 1nm, which was calculated by a simple method based on local density function theory.
