Study Of The Physicochemical Analysis Of Biodiesel Produced From Waste Vegetable Oil.

The study of the physicochemical analysis of biodiesel produced from waste vegetable oil in Sedi Minna Nigeria was carried out in order to ascertain the quality of the biodiesel produced as regards physical and chemical parameters which include visual appearance colour cloud point flash point and cetane index diesel index kinematic velocity calorific value. Biodiesel is a renewable resource that can replace petroleum diesel which comes from fossil fuels that are limited and will be exhausted in the near future. Biodiesel can be made from the transesterification of vegetable oils animal fat greases and oil crops such as soybean and it is biodegradable. The biodiesel produced was subjected to physicochemical analysis and results of cetane index was established to be 52 the flash point using pensky martens close cup was determine to be 1600C diesel index using IP21 0.3411 kinematic viscosity at 400C to be 4.12 and calorific value of 10867calg. The investigated physicochemical parameters show that the biodiesel produced is suitable for use in diesel engines without modifications and is cheaper to produce compared to petroleum diesel.
