Optimization process parameters of preparation Activated carbon for carbon dioxide adsorption: Taguchi approach and isotherm study / Ku Muhd Hanif Ku Ahmad

Activated carbon is often used in numerous applications and very useful adsorbent. The aim of this research project is to develop an understanding on the parameters and level of the activated carbon production process using Taguchi Orthogonal Array design method. The orthogonal array design, analysis of variance (ANOVA), signal-to-noise ratio (S/N ratio), regression model and prediction for optimized value were used to investigate carbon dioxide (CO2) adsorption efficiency. The control parameter investigated in this study were activation time, impregnation ratio and activation temperature. The statistical findings showed that the conditions that are optimized are the activation time of 30 min, impregnation ratio of 0.3 and the activation temperature of 700°C. The activation temperature has the greatest impact on carbon dioxide adsorption based on the highest delta in S/N ratio analysis. The linear regression model was performed and the result was well comparable between the simulated data and experimental data with R2 of 0.6159. The adsorption equilibrium data was well suited to the Freundlich isotherm.
