materials are good and cheap precursors for the production of activated carbon. In this
study, activated carbonswere prepared from the pyrolysis of soybean oil cake at 600 and 800 ◦C by chemical
activation with K2CO3 and KOH. The influence of temperature and type of chemical reagents on the
porosity development was investigated and discussed. K2CO3 was found more effective than KOH as a
chemical reagent under identical conditions in terms of both porosity development and yields of the activated
carbons. The maximum surface area (1352.86m2 g−1)was obtained at 800 ◦C with K2CO3 activation
which lies in the range of commercial activated carbons
