Biodiesel yield based on the different oil composition and mixture ratio

Abstract

Biodiesel is a renewable resource that can be grown quite literally from the ground up. It is a form of diesel that is derived from the transesterification of fatty acids within the oils of plant or animal-based products. These oils have a unique structure that could be varied owing to many factors; temperature, pressure, water, etc. This research looked into the justification for different molar ratio 4:1, 6:1, and 8:1. Owing to the composition and structure of the oils needed to achieve a better yield. Waste Vegetable oil mixed with methanol in proportions of 23.66 grams of lye in the methanol for every subsequent gallon of waste vegetable oil. Results showed that at high fatty Acid Value, the catalyst amount needs to be adjusted with operating temperature in the range of 60- 70 0c to produce yields up to 92-96%. While many forms of raw oil can be used in the production of biodiesel batches, the choice of modification/improvement on the process must be backed by proper storage measures. The oil chosen for this research was based on the reactive properties and fatty acid chains of waste vegetable oils. The sequences of production has minimal human involvement with support from the Raspberry Pi 3 software which signals different operational commands for producing biodiesel by activating a series of valves, pumps, and temperature devices in order to control liquid flow into & out of different reaction tanks.
