The quest of moving from conventional diesel fuels to alternate fuels is never-ending.Renewable diesel stands out as it has a similar molecular structure to that of diesel.Renewable diesel from hydroprocessing of Jatropha oil in presence of ruthenium catalyst is not much researched and the same has been worked upon in this paper. The objective of this paper is to analyze physiochemical properties of renewable diesel (R100), biodiesel (B100), and blends of diesel (D100) and renewable diesel and to check the operational feasibility. Renewable diesel was mixed in 10%, 20%, 30%, 40%, and 50%, by volume in diesel. It was observed that renewable diesel had better cold flow properties than diesel. Calorific value (CV) of renewable diesel and biodiesel was 1.84% and 3.92% less than diesel respectively. Present study shows up to 30% renewable diesel in diesel is a substitute fuel, as their viscosities (2.55, 2.60, 2.64cSt), densities (834.4 kg/m 3 , 831.87 kg/m 3 , 830.6 kg/m 3 ) and CVs (42.42 MJ/kg, 42.30 MJ/kg, 42.09 MJ/kg) are close to diesel (2.42cSt, 837 kg/m 3 and 42.57 MJ/ kg). This is also confirmed by a storage stability test conducted for 24 weeks. Cetane number of blends of R100 greater than 30% are found to be high; this can interfere with engine power output hence requiring amendments in current engines, which is not possible, therefore it is feasible to use blends only up to 30% of R100. GC-MS and Fourier transform infrared radiation showed a higher number of hydrocarbon atoms with diminutive oxygen percentage in R100, vis-a-vis, higher levels of unsaturation with more oxygen in B100.

“…Renewable fuel may be used as a partial solution or combination with any percentage of petroleum-based diesels, without altering the engines or vehicle fuel tank design [54]. The low carbon intensity of renewable diesel produced from organic waste oils/animal fats is also attributed to the enhanced fuel quality [55].…”

First, second, third, and fourth-generation biofuels are continuously evolving as a promising substitute to petrodiesel catalyzed by energy depletion, economic and environmental considerations. Bio-diesel can be synthesized from various biomass sources, which are commonly divided into FAME and renewable biodiesel. FAME biodiesel is generally produced by the transesterification of vegetable oils and fats while renewable diesel is produced by hydro-deoxygenation of vegetable and waste oils and fats. The different generation, processing technologies and standards for FAME and renewable biodiesel are reviewed. Finally, the life cycle analysis and production cost of conventional and renewable biodiesel are described.

“…This puts a challenge on researchers to discover renewable energy source, alternative fuels in diesel engines, and to improve its performance [7]. Bio-oils such as edible and non-edible oils can be considered as the possible alternative fuel sources since these are readily available and are biodegradable [8,9]. Researchers have been focusing on non-edible oil, mostly due to the food security issue.…”

The demand for fuel is increasing, and the availability of fossil fuel reserves is limited. The amount of concern arising from the emission problems causing the environment and ecosystem are increasing exponentially. It requires the industry to find the optimum solution. Biodiesel can be stored and used as petroleum diesel. It can be used in blended or pure forms without any modification in the engine. Use of bio-diesel has shown a remarkable reduction of toxic emissions and noise and emissions. This research deals with the use of Jatropha oil as biodiesel to improve the emission characteristics; at the same time, the performance characteristics need to be improved. The diesel engine is optimized with different blends of Jatroha oil as biodiesel, compression ratio, and load using L27 orthogonal array of full factorial design of experiment. The emission parameters, such as HC, CO, and CO2 are measured. The performance parameters viz brake power, brake thermal efficiency, specific fuel consumption, and volumetric efficiency are calculated. The entropy method determines the weight. Optimization is performed using multi-criteria decision-making technique with the TOPSIS method.The results show that blend B10 and a compression ratio of 15 found to be the optimum setting for diesel engine using biodiesel blends to optimize the performance.
