| Summary: | Powdered activated carbons (PACs)were produced fromoil palmempty fruit bunches (EFB) by varying the
operating parameters of temperatures, CO2 gas flow rates and activation times using 2-level full factorial
experimental design. The EFB samples were first carbonized for 30 min using nitrogen gas followed by
physical activation using CO2 to optimize best production conditions. The optimum conditions for PACs
produced were investigated through adsorption tests on aqueous solution of phenol. The results of this
studydemonstrated that the activation temperature with the range of 800–900 ◦C had themost significant
effect on the adsorption characteristics aswell as the yield of the activated carbon produced. Based on the
analysis of variance (ANOVA) and model equation developed, the optimum production conditions for the
EFB PAC were found to be at the activation temperature of 900 ◦C with CO2 gas flow rate of 0.1 L/min and
activation time of 15 min. Characterization of PAC produced showed that the activation conditions would
find good-quality adsorbent with the BTE surface area of 345.1m2/g and well forming pores distribution |
