Biodiesel production and optimization from Calophyllum inophyllum linn oil (honne oil) – A three stage method

The present work examines the production of a biodiesel from a non-edible oil namely honne oil (Calophyllum inophyllum linn). A three stage process viz., pre-treatment, alkali catalyzed transesterification and post treatment adopted for the production is discussed. The reaction parameters such as methanol to oil molar ratio, catalyst concentration, temperature and time have been optimized for the production of biodiesel. The yield of biodiesel from the honne oil under the optimized conditions is found to be 89%.
