Catalytic Esterification and Transesterification Reaction of High Acidic Value Waste Oil by Microwave Heating
Ayas, Nezihe; Yılmaz, Özlem (Wiley, 2015)In this study, biodiesel production from waste cooking oil was investigated. Esterification and transesterification reactions were carried out under microwave irradiation using heterogeneous (Amberlyst-15) and homogeneous ... -
A shrinking core model and empirical kinetic approaches in supercritical CO2 extraction of safflower seed oil
Ayas, Nezihe; Yılmaz, Özlem (Elsevier, 2014)Utilization of supercritical CO2 in safflower seed extraction was performed using a semi-batch extractor. Different extraction parameters, such as 40-60 MPa pressure, 323-347 K temperature, 20-76 min time, and 1-3 mL/min ... -
Thermodynamic modeling of the water-gas shift reaction in supercritical water for hydrogen production
Demirel, Etli Pınar; Ayas, Nezihe (Maik Nauka/Interperiodica/Springer, 2017)In this study, a computational model is developed for the estimation of the equilibrium composition of WGSR (water gas shift reaction) based on the stoichiometric and nonstoichiometric thermodynamic approaches. The model ... -
USING OF Fe/ZrO2 CATALYST TO REMOVE DIRECT ORANGE 26 FROM WATER BY FENTON OXIDATION AT WIDE pH VALUES
Ayas, Nezihe; Aşçı, Yeliz; Yurdakul, Merve (Parlar Scientific Publications (PSP), 2016)In the present study, in order to promote the practical application of the heterogeneous Fenton oxidation in wastewater treatment, Fe/ZrO2 catalyst was prepared and used in decolorization of Direct Orange 26 (DO26) over a ... -
