Calophyllum Oil Prospective as Alternate Fuel for Diesel Engine

Rapid depletion of fossil fuels, increasing fossil-fuel price, carbon price, and the quest of low carbon fuel for cleaner environment – these are the reason researchers are looking for alternatives of fossil fuels. Biodiesel is a gifted substitute as an alternative fuel has gained significant attention due to the predicted littleness of conventional fuels and environmental concern. The utilization of liquid fuels such as biodiesel produced from Calophyllum inophyllum oil by transesterification process represents one of the most promising options for the use of conventional fossil fuels. The Calophyllum inophyllum oil is converted into Calophyllum inophyllum methyl ester known as biodiesel processed in the presence of homogeneous acid catalyst. The physical properties such as Kinematic viscosity, Density, Calorific Value, Cetane number, Fire point and Flash point were found out for Calophyllum inophyllum methyl ester at different blends.

Hydrocracking of Calophyllum inophyllum Oil Employing Co and/or Mo Supported on γ-Al2O3 for Biofuel Production

Cobalt and/or Molybdenum based catalysts were simply dispersed on γ-Al2O3 through wet impregnation. The set of prepared monometallic and bimetallic catalysts of aCoO/γ-Al2O3, aMoO/γ-Al2O3, aCoOaMoO/γ-Al2O3, and bCoObMoO/γ-Al2O3 were investigated and evaluated in the hydrocracking of Calophyllum inophyllum (CIO) which is not a food crop as well as rich in unsaturated fatty acid that potential to be converted into biofuel. Out of the prepared catalysts, aCoOaMoO/γ-Al2O3 with total metal content, acidity, and specific surface area of 13.62 wt%, 5.01 mmol.g-1, and 107.67 m2.g-1, respectively, showed the best catalytic performance. The high metal loading of aCoOaMoO/γ-Al2O3 is favorable by producing 65.56 wt% liquid fraction through carbocation formation mechanism. It was selective to produce 8.61 wt% gasoline and 5.01 wt% diesel. Copyright © 2020 BCREC Group. All rights reserved
