Flue gas desulfurization by citrate process and optimization of working parameters
Akyalçın, Levent; Kaytakoğlu, Süleyman (Elsevier Science Sa, 2010)In this study, model flue gas was bubbled into 0.25 L tribasic sodium citrate (TSC) solution being in 0.5 L glass absorber to remove its SO2 content. Size of gas bubbles, absorption temperature, gas flow rate, solution ... -
Optimization of desilication parameters of low-silica ZSM-12 by Taguchi method
Akyalçın, Sema; Akyalçın, Levent; Bjorgen, M. (Elsevier Science BV, 2019)Zeolite ZSM-12 was synthesized by a direct hydrothermal method and subsequently desilicated by alkaline treatment under different conditions. Changes in the properties of the zeolite samples were investigated by XRD, ... -
Optimization of parametric performance of a PEMFC
Kaytakoğlu, Süleyman; Akyalçın, Levent (Pergamon-Elsevier Science LTD, 2007)In this study, the Taguchi method was applied to determine optimum working conditions in obtaining maximum power density of a PEMFC. Performance measure analysis was also followed by performing a variance analysis, in order ... -
Optimization of structural combinations on the performance of a PEMFC's MEA
Akyalçın, Levent; Kaytakoğlu, Süleyman (Elsevier Science BV, 2008)In this study, the Taguchi method was applied to determine optimum structural combination of a membrane electrode assembly (MEA) in obtaining maximum power density of a PEMFC. Performance measure analysis was also followed ... -
The Seebeck coefficient and the Peltier effect in a polymer electrolyte membrane cell with two hydrogen electrodes
Kjelstrup, S.; Vie, P. J. S.; Akyalçın, Levent; Zefaniya, P.; Pharoah, J. G.; Burheim, O. S. (Pergamon-Elsevier Science LTD, 2013)We report that the Seebeck coefficient of a Nafion membrane cell with hydrogen electrodes saturated with water vapour, at 1 bar hydrogen pressure and 340 K, is equal to 670 +/- 50 mu V/K, meaning that the entropy change ...
