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.
