| This paper introduces a cheap local Ricinus communis, which grows in Jahrom, a warm region of southwest Iran, as a renewable energy source. Biodiesel production was investigated by employing CaO and C:CaO as heterogeneous catalysts and KOH as a homogenous catalyst. Conventional and ultrasonic-assisted methods were used considering different methanol to oil molar ratios (4:1, 6:1 and 8:1) and different temperatures (40 ˚C, 50 ˚C and 60 ˚C). The optimized production condition was assessed by response surface methodology (RSM). The results showed that the most suitable catalyst was C:CaO with a methanol to oil molar ratio of 6:1 and temperature of 60 ˚C. Using carbon with CaO increased biodiesel yield by around 20% compared to CaO alone. In all conditions,... |
