Preparation and Characterization of Activated Carbons Obtained from Maize Cobs by Zinc Chloride Activation

An oil palm empty fruit bunch-derived activated carbon has been successfully produced by chemical activation with zinc chloride and without chemical activation. The preparation was conducted in the tube furnace at 500oC for 1 h. The surface structure and active sites of activated carbons were characterized by means of Fourier transform infrared spectrometry and field emission scanning electron microscopy. The proximate analysis including moisture content, ash content, bulk density, pH, and pH at zero charge was conducted to identify the psychochemical properties of the adsorbent. The results showed that the zinc chloride-activated carbon has better characteristics compared to the carbon without chemical activation.

Two Factors

Activated carbons were prepared from rambutan seed with impregnation of zinc chloride as dehydrating agent. In order to find its characteristics, different zinc chloride to rambutan seed ratio (0.5 and 2) and activation temperature (450 and 650 °C) was employed. The carbonization occurred in a tube furnace with flow of nitrogen gas at 0.5 L/min. The results showed that at higher impregnation ratio and carbonization temperature produced a wider BET surface area of activated carbon that was 9.8761 m2/g. Total pore volume also increased with increases of these two factors. However activation yield was decreased with increasing of carbonization temperature.

Scanning Electron

A series of different activated carbons of both honeycomb and disc type were prepared by chemical activation of coconut shells with zinc chloride at different concentrations, without the use of a binder. The structures were characterized by N2adsorption at 77 K and scanning electron microscopy (SEM), and also some samples were characterized by immersion calorimetry in benzene. These were subsequently used in the adsorption of phenol in aqueous solution. The experimental results indicat that activation with zinc chloride produced a large development of microporosity with a micropore volume of 0.38 to 0.79 cm3g-1, BET area between 725 and 1523 m2g-1and the capacity to adsorb phenol. In addition, the BET and Langmuir models were applied to isotherm data.
