Lignocellulosic materials from agricultural by-products were used to develop high surface area
activated carbons by chemical activation using KOH pellets. Surface and textural
characterizations of the activated carbon were respectively investigated using micrometrics and
BET technique at low temperature (77K) of nitrogen. It was observed that the optimum
activation temperature for the production of activated carbon from corncobs was 7000C and the
temperature had no appreciable effect on both the apparent and solid densities of the activated
carbons. Minor crude oil spillage was simulated and the adsorptive capacity of the adsorbent on
crude oil removal was investigated at ambient conditions. Purity indices of the adsorbate were
investigated before and after the adsorption experiment. Maximum adsorption of 17.2 % was
observed with the corncobs activated with KOH at 7000C against 24.6% for the commercial
