Karacan F., Togrul T., Karacan S., 2014, A Modeling Optimization of Photocatalytic Liquefaction of Turkish Lignites using Response Surface Methodology, Chemical Engineering Transactions, 39, 487-492.
In this study, the application of response surface methodology for modelling the influence of some operating variables such as reaction time, UV irradiation power and photocatalyst (TiO2 and ZnCI2) on the performance of liquid yields. The regression analysis, statistical significance and response surface were done using Design Expert Software for predicting the responses in all experimental regions. Mathematical Models demonstrate the functionality of different parameters to the three operating variables and their interactions based on the ANOVA analysis. Predicted values were found to be in good agreement with experimental values. Using numerical optimization, the optimum conditions for manufacturing of photocatalytic liquefaction of Turkish lignites, which were based on response surface and contour plots, were found as follows: reaction time of 7.12 days, UV irradiation power of 141 W and ZnCI2 photocatalyst.
