Over the years, microwave power has been used as a control parameter for the preparation of activated carbon (AC) via microwave heating due to the volatile nature of temperature inside the microwave. This paper investigates the use of bed temperature as a control parameter for the preparation of activated carbon using microwave heating. Activated carbon has been prepared from an oil palm shell (OPS) in a two-step microwave-induced CO2 activation. The response surface methodology (RSM) and Box-Behnken design (BBD) were utilized to optimize the operating parameters of the preparation process. The influences of the three preparation parameters namely, bed temperature, activation time and CO2 flow rate on the porosity of the AC and the AC yield were investigated to identify the significant parameter(s) using the analysis of variance (ANOVA). The optimum preparation conditions as identified from ANOVA are bed temperature of 900 oC, the ctivation time of 40 min and CO2 flow rate of 400 cm3 min-1. The AC prepared at optimum conditions had a BET surface area (SBET) of 574.37 m2 g-1, total pore volume (Vt) of 0.244 cm3 g-1, micropore volume (Vμ) of 0.198 cm3 g-1 and yield of 74.06%.
