The treatment of oilfield produced water for reuse using activated carbons (AC) derived from palm kernel shells (PKS) biomass was studied. The biomass (PKS) was prepared and converted to Biochar by pyrolysis and then activated with 0.2M HCl at a temperature of 450oC. The AC (adsorbent) produced was characterised for pH, bulk density, particle size, iodine number, ash and moisture contents. The characteristics of the adsorbent indicate that the iodine numbers ranged from 525.10-918.93mg/g for particle sizes 150-1180 μm); ash content ranged from 2.00-2.80% PKS. Moisture content could get as low as 1.6% for PKS when warmed in an oven at 105oC for 1 hour. The acid concentration and adsorbent particle size were optimized; and based on iodine number, the 300μm particle size (with pH = 7.4, iodine number=918.93, moisture=6.2% and %ash=2.00) showed good prospect for removing contaminants from produced water. It is recommended that the conversion of Elaeis Guineensis biomasses, especially palm kernel shells (PKS), to activated carbon should be encouraged for oilfield produced water treatment in the production phase of the petroleum industry because of its high adsorptive capacity. To improve the adsorption capacity of the PKS, it is also recommended that any other stronger activation reagents should be used to activate PKS because of its bulk density.
