Abstract

This study was performed to extract oil from Roselle seeds and to investigate the production of biodiesel fuel from crude Roselle oil by using alkali- catalyzed transesterification process. On the other hand, The process of alkali-catalyzed transesterification with methanol was carried out to examine the effects of reaction variables on the Roselle biodiesel yield percentage these variables included catalyst concentrations of 0.25–2.0% wt/wt of Roselle oil taken, oil to methanol molar ratios of 1:3–1:9, of oil, reaction temperatures of 30–75 o C, and reaction times of 20– 60 min. The Roselle oil extracted was analyzed by gas chromatography (GC), the optimum condition for produced Roselle biodiesel having been achieved at a catalyst concentration of 0.5% w/w of oil, a oil to methanol molar ratio of 1:3, a reaction temperature of 65 o C, and a reaction time of 40 min. At those conditions The Roselle biodiesel obtained analyzed and compared with international standards specifications ASTM found have a good specification.
