Abstract
The paper focuses on biodiesel production from kusum oil using esterification reaction followed by transesterification reaction in an in-house batch reactor setup. The effects of methanol to oil ratio (M/O), catalyst amount (H2SO4 and methodoxide) and reaction temperature on acid value and fatty acid methyl esters (FAME) is studied. Product has been analysed using FTIR spectroscopy technique for confirmation of ester group in biodiesel. Experimental data was optimized by Taguchi analysis to conclude the optimum variable affecting the response. In both processes M/O ratio has the significant effect for biodiesel production. The obtained biodiesel properties are close to commercial diesel fuel and may be rated as an alternative to conventional diesel. The biodiesel production will enhance the maximum utilisation of forestry or agricultural products.

Summary
All over the world demand of fuel is increasing because of the limited availability of fossil fuel resource and its increased usage. Many researchers work dedicatedly to use vegetable oil derived fuels in existing diesel engines. Use of raw vegetable oils is restricted in diesel engine due to their unfavorable physical properties, their viscosity [3]. Biodiesel has similar properties to that of diesel produced from crude oil It is biodegradable, can be used in existing engines without modifying and it produces less harmful gas like sulphur dioxide [7] [8] [9]. The most important alternative resource for biodiesel production is non-edible oil which is not used for human consumption and could get bulk quantity by means of agricultural or forestry product. Most of the non-edible oils have high free fatty acid (FFAs) contents, which increase the cost of biodiesel production [11]
