“…Signicant fuel characteristics of GTL, like higher hydrogen-carbon ratio, higher CN and very low aromatic content assist in improved combustion and thus cause reduction of CO emission. 43 Higher CN results short ignition delay, leading towards better combustion. Besides, the lower distillation temperature of GTL fuel induces rapid vaporization, which reduces the probability of ame quenching and thus ensures lower CO emission.…”

This study focuses on the physicochemical fuel characteristics and engine performance-emission features of three prospective alternative transportation fuels: Alexandrian laurel biodiesel (ALBD), jatropha biodiesel (JBD) and GTL fuel at high idling conditions. The blends of GTL fuel (G10, G20), JBD (J10, J20) and ALBD (AL10, AL20) with diesel had been investigated in a multi-cylinder diesel engine at different load-speed conditions. Analysis of the fuel properties showed a linear variation of the major fuel properties with an increase of alternative fuel quantity in the blends. Engine performance test results revealed an average decrease of brake specific fuel consumption (BSFC) (ca. 8.65-12.26%) and brake specific energy consumption (BSEC) (ca. 8.27-11.51%), but a higher brake thermal efficiency (BTE) (ca. 8.56-12.58%) by GTL blends, whereas, the biodiesel blends showed higher BSFC (ca. 5.01-12.18%) and BSEC (ca. 3.41-9.67%) and lower BTE (ca. 3.68-9.93%), respectively, than those of diesel. Referring to the emission analysis, the results revealed that GTL blends showed a slight reduction in NO x (ca. 3.89-6.85%), but a significant reduction in CO (ca. 48.25-51.38%), HC (ca. 44.81-51.43%) and smoke (ca. 15.21-18.78%), respectively, when compared to diesel. The biodiesel blends demonstrated reduced CO (on average ca.29.12-33.71%), HC (ca. 29.67-35.46%) and smoke (ca. 2.49-6.87%), but increased NO x (on average ca. 2.83-9.81%), respectively, than those of diesel.

Currently, more than 95% of biodiesel is being produced from edible vegetable oils which may affect the sustainability of biodiesel industries. Rubber seed oil (RSO) is one of the promising non-edible oil for biodiesel synthesis. Higher free fatty acid content of RSO was reduced by ultrasonic assisted esterification reaction. Non-conventional techniques, ultrasonic horn and ultrasonic bath for transesterification of esterified RSO (ERSO) were studied to enhance the yield of rubber seed oil methyl esters (ROME). The effect of transesterification parameters; molar ratio (MR) of methanol/ERSO (3:1-13:1), reaction time (5-50min) and heterogeneous catalyst Ba(OH) 2 ·8H 2 O (2-10wt%of feedstock) on conversion of RSO were investigated and optimized for maximum yield of ROME. The physico-chemical properties of ROME and its various blending with diesel (RDXX) were estimated to suite diesel engine for efficiency (BTE) was achieved at 80% load with RD10 (28.36%) compared to neat diesel (24%) and a drastic improvement of overall 13% increase at all loads. Maximum exhaust gas temperatures for biodiesel blends were found to be lower than neat diesel with rise in pressure by about 4% which ultimately shows slight improvement in the net heat release rate. The emissions of CO, CO 2 and NO X were reduced with the use of ROME blends.

“…Many studies have been conducted with pure biodiesel and its blend which shows promising result for short duration experiments [2][3][4][5]. Though encouraging performance in short term operations, biodiesel contribute to several operating issues such as carbon deposition, engine oil dilution and its degradation, injector coking, fuel filter plugging and wear related concern, especially corrosive wear in long term tests [6,7].…”
