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 ... -
Microwave assisted transesterification of waste frying oil and concentrate methyl ester content of biodiesel by molecular distillation
Azcan, Nezihe; Yılmaz, Özlem (Elsevier Sci LTD, 2013)In this study, microwave assisted transesterification of waste frying oil was carried out in the presence of sodium methoxide (NaOCH3). Parametric studies were performed to investigate suitable reaction conditions such as ... -
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 ...
