Use Of Fusel Oil As Alcohol In The Production Of Biodiesel From Raw Crude Oil
Journal Title: Gazi Mühendislik Bilimleri Dergisi - Year 2018, Vol 4, Issue 2
Abstract
Pomace oil is a valuable byproduct as waste oil that obtained from olive oil after the production of olive oil, in Turkey. Fusel oil is a waste alcohol mixture that occurs during the proction of molassess left over during the production of sugar from sugar beet. Biodiesel is plant-derived fuel, obtained from fatty acids that is adapted for engines with the help of alcohol and catalyst. The objective of this study was to investigate the producibility of bio-diesel using two waste exist in Turkey. In this study, transesterification method is used for production of bio-diesel. The water inside of fusel oil was removed by distillation and used as alcohol stuff in biodiesel production. As pomace oil contains a high free fatty acid (FFA), a two-stage biodiesel production method is determined. First, to reduce the amount of FFA inside of pomace oil, in various proportions it is exposed to sulfuric acid treatment at different temperatures and reaction for different durations. Pomace oil with reduced amount of FFA, then, biodiesel conversion efficiency was investigated using sodium hydroxide (NaOH) catalyst in different ratios by weight. As a result of the study, at 65 oC, at rate of 10:1 mol fusel oil/pomace oil, with % 1 NaOH catalyst, % 78 biodiesel conversion efficiency was discovered.
