Acid and Base Catalyzed Transesterification of Animal Fats to Biodiesel
The present study has been focused on the acid and base transesterification of animal fats (dairy cow and beef) to produce biodiesel by varying process parameters such as catalyst amount, catalyst nature, reaction time and temperature. The maximum biodiesel yield after acid catalysis was 94.1 ± 2.43 and 98.4 ± 2.3 percent for dairy cow and beef t...
متن کاملBiodiesel Production from Chlorella protothecoides Oil by Microwave-Assisted Transesterification.
In this study, biodiesel production from microalgal oil by microwave-assisted transesterification was carried out to investigate its efficiency. Transesterification reactions were performed by using Chlorella protothecoides oil as feedstock, methanol, and potassium hydroxide as the catalyst. Methanol:oil ratio, reaction time and catalyst:oil ratio were investigated as process parameters affecte...
متن کاملFuel Characteristics of Biodiesel Produced from a High-Acid Oil from Soybean Soapstock by Supercritical-Methanol Transesterification
A supercritical methanol transesterification method was applied to produce biodiesel from the high-acid oil of soybean soapstock. The fuel properties of biodiesel produced with various molar ratios of methanol to raw oil were analyzed and compared in this experimental study. Oleic acid (C18:1), linoleic acid (C18:2), and palmitic acid (C16:0) were the three main compounds in the high-acid oil-b...
متن کاملBiodiesel production from neem oil using two step transesterification
Currently, most of the biodiesel is produced from the edible/refined type oil using methanol and alkaline catalyst. However, large amount of non-edible type oils and fats are available in our country. In this study, crude neem oil is used as alternative fuel for biodiesel production. The difficulty with alkaline transesterification of these oils have contained large amounts of free fatty acids ...
متن کاملEvaluation of Biodiesel Blending of Cocos Nucifera Oil Methyl Ester Produced from Alkaline-Catalyzed Transesterification Reaction
The prospect of using cocos nucifera Oil for production of biodiesel via transesterification reaction was investigated. The use of ethanol for the transesterification reaction instead of methanol was also evaluated. Test quantities of biodiesel were produced using 100 g, 20.0% and 0.8% of </span...
