Abstract
This research focused on BDF production from Jatropha seed oil and evaluation of its exhaust gas on the diesel engine in order to produce and confirm the environmental benefit of BDF. This report showed the results of research on BDF production from Jatropha seed oil and engine emissions from blend of diesel fuel and BDF from Jatropha oil. A maximum of 78% biodiesel yield was found at 2.25%w/w catalyst KOH, the optimum molar ratio of Jatropha oil to methanol of 1:6, at a reaction temperature of 550C in 45 minutes. The use of BDF blends in conventional diesel engine results in substantial reduction in emission of hydrocarbon CxHy, carbon monoxide CO and sulfates SO2, whereas NOx emission increases a little. The reason for reducing of CxHy, CO and SO2 emission and increasing NOx emission with biodiesel mixtures was mainly due to the presence of oxygen in their molecular structure.
