Process Optimization of Garcinia Gummi-Gutta for Production of Biodiesel and Performance and Emission Characteristics of Biodiesel Blends in Diesel Engine

The aim of the project is to maximize the yield of biodiesel from Garcinia Gummi-Gutta crude oil using heterogeneous catalyst (CaO) by optimizing four process parameters. And the performance and emission characteristics test is conducted in CI engine by using biodiesel blends B20, B40, B60, B80, and B100. The maximum biodiesel yield of 92.7% is achieved by using CCD of RSM in an optimum condition at molar ratio 9:1 by using 0.8% of catalyst concentration in 45 min of reaction time at 500C temperature. Whereas predicated yield at 94.14%. The biodiesel produced from the GG at optimum conditions satisfies the relevant quality standards. The experimental evaluation of performance and emission characteristics of the biodiesel blends prepared by using GG biodiesel. The blends are prepared by preparing the blends of B20, B40, B60, B80, and B100.The performance and emission characteristics of blends are compared with the diesel. The performance parameters such as BP, BTE, and SFC are observed. There is a small reduction of BP for all the blends 6.65% reduction of BTE for B20. The fuel consumption of B20, B40, and B60 is decreased by 9.67%. The emission of CO, HC and smoke opacity is decreased whereas CO2 and NOX are slightly increased due to oxygen present in biodiesel.
