摘要
Rice husk was chemically activated with saturated KOH solution and the activation temperature was varied from 400 to 700 °C to generate activated carbons with different textural characteristics. Activated carbons were investigated for their ability to adsorb CO2. We selected Langmuir, Freundlich, Sips and Radke-Prausnitz equations to fit the experimental CO2 adsorption data. In order to determine the effect of using different error standards when calculating isotherm model parameters, an error analysis was conducted. The Radke-Prausnitz model shows the best fit to CO2 adsorption and calculated adsorption capacity correlates closely with experimental data.
