Preparation of Activated Carbon Derived from Rice Husk by Simple Carbonization and Chemical Activation for Using as Gasoline Adsorbent

Arunrat Cheenmatchaya and Sukjit Kungwankunakorn
Abstract—Rice from Thailand is the top ranking of the world. The by-product of rice manufacturing is rice husk, which its usefulness is not fully attempt. The aims of research are to make value-added activated carbons of rice husk and to study the optimum conditions for gasoline adsorption using these activated carbons as adsorbents. All samples were analyzed for gasoline adsorption by gas chromatograph-mass spectrometry (GC-MS). The activated carbon of rice husk, which activated by H3PO4 at temperature of 450 °C, has the highest adsorption capacity. According to gasoline adsorption study, the optimum conditions were 0.1 g of activated carbon, 70 °C of adsorption temperature and 30 minutes of adsorption time. Physical characterization of the activated carbon obtained was performed by scanning electron microscopy (SEM). The results present that the activated carbon of rice husk possesses a high apparent surface area (SBET = 336.35 m2/g). They thus encourage the use of activated carbon of rice husk as an adsorbent for the qualitative analysis of gasoline in order to apply for gasoline sampling in arson case and to reduce the analysis cost from commercial adsorbent.

Index Terms—Rice husk, activated carbon, gasoline, adsorption.
