Basic Heterogeneous Catalyst Design for the Production of Soybean Oil Methyl Esters
Journal Title: Gazi Üniversitesi Fen Bilimleri Dergisi Part C: Tasarım ve Teknoloji - Year 2015, Vol 3, Issue 1
Abstract
In this study, hydroxyapatite (HAP) was prepared by using the co-precipitation method and used as a catalyst support material. 25 % KOH loaded HAP catalyst was prepared by wet-impregnation method and basicity of synthesized catalyst was found to be 1.6 mmol/g. Synthesized solid basic catalyst was tested for the soybean oil transesterification with methanol at different reaction temperatures (25-65°C) and different alcohol/oil molar ratios (6/1-15/1) when catalyst amount of 3 wt.% and reaction time of 5 h were kept constant. The chemical structure and purity of the fatty acid methyl esters obtained in this study was verified by the ATR-IR spectroscopy method. Methyl ester yield of 93.3% was obtained by using KOH loaded HAP solid basic catalyst which was found to be very successful catalyst.
