▎ 摘　　要

NOVELTY - The calophyllum inophyllum graphene nanoparticle contains free fatty acid (FFA) content of procured oil which is greater than 2% not acceptable according ASTM standards. The two phase esterification is done to improve the properties of crude oil. The alcohol esterification is carried at constant temperature for 3-4 hours duration and the transesterification process setup. USE - Calophyllum inophyllum graphene nanoparticle used as fuel for diesel engine. ADVANTAGE - The fuel characterization is improved and the performance and combustion attributes of the engine is enhanced. The engine attributes are enhanced by reducing harmful emissions. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the transesterification process setup.
