Abstract

Use of Jatropha Oil Methyl Ester and Its Blends as an Alternative Fuel in Diesel Engine

Jatropha ( Jatropha curcas L.).

“…Kaushik et al (2007) explored the variability in Haryana, India accessions to find wide variation in 100-seed weight (49-69 g) and oil content (28-39%). Similarly, Rao et al (2008) found wide variation in 100-seed weight (57-79 g) and oil content (30-37%) for Andhra Pradesh, India, accessions.The study conducted at ICRISAT on progeny trial evaluation comprising 99 jatropha accessions collected from different agro-eco regions of India and planted during 2006 showed great variability in plant height (105-274 cm), collar diameter (5.1-18.9 cm), number of branches (9.7-66.3), crown area (0.5-6.3 m 2 ), volume index (8056-85,708 cm 3 ), seed length (11.6-19.3 mm), seed width (9.5-11.7 mm), seed thickness (7.6-11.0 mm), 100-seed weight (38.9-67.1 g) and seed oil content (27.5-40.5) (Table 15.6). ICJC06116 recorded the highest 100-seed weight of 67.1 g. Genotype ICJC06004 recorded the highest plant height (274 cm) and ICJC06087 the highest volume index (85,708 cm 3 ) and collar diameter (18.9 cm).…”

“…However, comprehensive work on a jatropha germplasm collection, characterization and evaluation for growth, morphology, seed characteristics and yield traits is still in its infancy. The fact that jatropha has adapted itself to a wide range of edaphic and ecological conditions suggests the existence of a considerable amount of genetic variability to be exploited for potential realization (Rao et al, 2008). Detailed and systematic provenance trials have not been carried out, and material from the centre of origin has not been sufficiently screened.…”

“…There are energy plants available that will produce a higher yield in kWh per area, but the simplicity of having a fuel that is fully compatible with present fuel and engine technology makes jatropha biodiesel very attractive. Jatropha biodiesel has good fuel properties, comparable to or even better than petroleum diesel (Rao et al, 2008). The cetane number (an indication of its fuel-burning efficiency) is 51-52 for biodiesel from jatropha oil, which is higher than the cetane number of most petroleum diesels.…”

“…Jatropha biodiesel has good fuel properties, comparable to or even better than petroleum diesel (Rao et al 2008 ) . Its cetane number (an indication of its fuel burning ef fi ciency) is 51-52 for biodiesel from Jatropha oil, which is higher than the cetane number of most petroleum diesels.…”

Comparative evaluation of biodiesel production and engine characteristics of Jatropha and Argemone Mexicana oils

“…The most common way to produce biodiesel in all scale is transesterification. It can be either alkali, acid or enzymatic catalyzed process [11]. Many researchers' suggest base catalyzed biodiesel conversion for lab scale in order to get maximum conversion of fatty acid methyl ester.…”
