Jatropha curcas methyl-ester

The preparation of Jatropha curcas methyl esters (JCME) and a study of their chemical and fuel properties are presented in this paper. The results are compared with those of petroleum diesels (Diesel No.2 and kerosene).

The experimental yields of the methyl esters from Jatropha curcas oils, prepared as shown in Figure 1, were determined to be in the range 90.7-96.2% by volume of oil. The losses in comparison to the 100% theoretical 5deld were attributed to the formation of salts of free fatty acids present in the oil, which is evidenced by the high acid value of the oil (5.2) as compared 0.2 of the resulting esters (Table 2).

In addition, a study of combustion of Jatropha curcas Linn, oil (cmde degummed fatty acid methyl ester) as a fuel in a direct injection diesel engine was done (Reksowardojo et al., 2008a, 2009a). The summary of conclusions drawn from the experimental data were as follows ...
