Project Summary

Primary energy resources such as petroleum and gas are depleting rapidly due to increased population and industrialization. In addition, combustion of such fuels is considered to be major cause of environmental pollution due to the release of toxic components i.e. NOx and SOx. Secondary resources such as lignucellosuic biomass are environmentally friendly and has shown considerable potential to meet the global energy demand. Biodiesel is a non-petroleum fuel produced by transesterification or esterification reactions. Materials from renewable sources, such as vegetable oils or animal fats and anhydrous alcohols with low molecular weight, are used as reactants in the process. Biodiesel is one of the alternative biofuels that can be used to replace crude oil as the main fuel globally. This is because biodiesel is biodegradable and nontoxic, and is associated with low gas emissions, due to the molecular structure of its main chemical components. Today, biodiesel is so versatile that it can be used in diesel engines without the need for prior modification of the mechanical parts. Transesterification is the most widely used reaction to produce biodiesel. It involves the breaking of the triglyceride structure and exchange of alkyl groups with the hydroxide group from alcohol, to obtain the new ester (i.e., biodiesel). The main purpose of transesterification is to reduce the viscosity and to increase the volatility of the vegetable oil. The reactions involved in biodiesel production can be homogeneously catalyzed to obtain maximum output within a relatively short time. However, oil extraction and conversion to biodiesel is still challenging from such materials. Moreover, to maintain the controlled environment for desired product quality is of great concern as well.

In this context, this work is focused on design and fabrication of automated laboratory scale plant for biodiesel production from soybean. The core objectives of study are as following
