Study on Pre-Esterification of Trench Oil and Preparation of Bio-Diesel

Abstract:

In this study, the trench oil was processed by the technology of polyol pre-esterification and the bio-diesel was prepared using basic ionic liquid 1-methyl-3-butyl-imidazole hydroxide as a catalyst. The amount of ionic liquids, alcohol and oil molar ratio, reaction temperature and reaction time were investigated on the transesterification reaction. The results showed that the bio-diesel prepared conditions by trench oil are as follows: alcohol and oil molar ratio of 8:1, reaction temperature 70°C, reaction time 110min and the amount of catalyst for the quality of raw materials 3.0% oil. Under these conditions, fatty acid methyl ester was 95.7% conversion rate.
