Metal Absorption

Research on metal adsorption isotherms with activated carbon oil palm empty fruit bunches in liquid waste. Oil palm empty fruit bunches are used as adsorbent for metal absorption. Oil palm empty fruit bunches are prepared at 105O C for 24 hours to get a constant weight then are characterized by SEM. Oil palm empty fruit bunches are heated at temperatures (400O C – 700O C) to get activated carbon. Re-characterization using SEM at optimum conditions shows that the pore surface is expanding. Then with a batch method for metal absorption (Cu, Pb, Hg) and analyzed using AAS. The most common absorption of activated carbon of oil palm empty fruit bunches is Cu (II). Based on the Langmuir and Freundlich R2 models close to 1, which means that multi-layer adsorption occurs.

The oil palm shell was subjected to multimode microwave pyrolysis at a fixed microwave power of 300W at 2.54GHz using intimately mix and layer microwave heating methods to observe process temperature, pyrolysis product and bio-oil composition at various levels of Coconut Activated Carbon (CAC). The results indicated that the layers method achieved higher bio-oil yield with complete uniformity of process temperature at high CAC loading compared to intimate mix method. The increased CAC loading increased selectivity towards phenol in bio-oil with maximum phenol 80.23 %area and 51.77%area under GC-MS at 75wt% CAC loading using intimately mix and layer method, respectively. The layer method produced a new product 1,1-dimethyl hydrazine of 11.24–13.01 %area in bio-oils which was not found of using intimately mix method. The 1,1-dimethly hydrazine is an important source of high energy fuel.
