The main objective of this work is the preparation of activated carbon by using Karanja oil seeds cakes which is a waste remain after the extraction of the karanja oil from the seeds by the method of Sulphuric acid (H2SO4) chemical activation. The karanja oil is used as an feedstock for biodiesel preparation and the cake is a waste which is thrown away with no further use, thus this can be used as a feed stock for the preparation of activated carbon. The characteristics and surface area of the prepared activated carbon were investigated. The experiments were carried out with carbonization temperature varied from 400°C to 550°C. The results show that in all cases, increasing the carbonization temperature the yield decreases. It was found that the specific surface area of activated was at a maximum value (about 343 m2/g) at carbonization temperature of 500°C and carbonization time 2.0 h .The XRD analysis shows that the phase change from amorphous to crystalline form has been taken place.
