Biochar was produced from oil palm shell via microwave-induced pyrolysis. The biochar was subsequently activated via microwave assisted CO2 activation. A simple single layer arrangement of the microwave absorber (coconut shell based activated carbon) and oil palm shell in the reactor was adopted during pyrolysis. In recent times, the treatment of oil palm biomass using microwave heating technology has been on the increase. Value added products such as bio-oil, gas, biochar and activated carbon are being produced while at the same time serving as waste management control. Biochar is seen as a promising climate mitigation tool. Activated carbons can be used as absorbent for the removal of pollutants from wastewaters, as air pollution control and as electrode for supercapacitor. This paper presents comparative study between the characteristics of oil palm shell biochar and oil palm shell activated carbon. BET surface area and Scanning Electron Microscopy (SEM) were analyzed to establish the characteristics of the biochar and activated carbon.

In this research, it has been performed carbon activation of oil palm shells (CAC) prepared by chemical treatment as adsorbents of phenol and methylene blue (MB) in solution either in the form of single or in pair solution. The activation of carbon from the oil palm shells was done physically at a temperature of 700°C for 1 hour continued with chemical activation using 10% H3PO4 for 24 hours. Identification of functional groups on the carbon from oil palm shell before and after chemically activated was performed using infrared spectrophotometer (IR) and analysis of its surface morphology was carried out using scanning electron microscope (SEM). The phenol and MB adsorption process was performed in single and binary systems using the batch method. The adsorption of phenol on CAC is optimum at pH 8 while MB at pH 11 with optimum contact time of 90 min for phenol and 120 min for MB respectively. The phenol and MB adsorption data on the CAC in the single system follow the pseudo-second-order kinetics model with the adsorption rate constant of 0.399 and 0.769 g mmol-1 min-1 respectively. The adsorption isotherms of phenol and MB in CAC tend to follow Freundlich adsorption isotherm pattern with the adsorption intensity factor (n) for phenol, MB, phenol/MB, and MB/phenol: 1.739, 1.341, 1.334, and 1.293 respectively. The adsorbent of CAC is effective to remove phenol and MB in solution, either in single or paired condition.
