Effects of Different Catalyst on the Production of Biodiesel From Jatropha Oil and Comparative Analysis

Abstract

The use of oils and fats of vegetable or animal origin as a fuel dates back to the late nineteenth century, when Rudolph Diesel, inventor of the internal combustion engine (named after him), used crude and peanut oil in his essays. As per the current seen of limitations of conventional energy resources, biodiesel has been a eye stars of the scientist of the world for the coming future. Bio-diesel is a renewable fuel for diesel engines derived from natural oils like vegetable oils. Bio-diesels can be used as fuel at varying concentrations with petroleum based diesel with little or no modification in existing diesel engines (Sanjib and Anju, 2005; Heywood, 1998).  Currently, there is a diversity of plants that can be used to obtain oil for biodiesel production. Among them are sunflower oil (42%) with yield of 1600 kg ha-1 and canola and crambe oil (38%) with yield of 1800 and 1200 kg ha-1, respectively. Soybeans have on average 18% oil from grains and yield of 2600 kg ha-1; it is the crop most used for biodiesel production in Brazil (Santos et al., 2008).
