Abstract

The world’s energy matrix can be diversified with biodiesel from castor and jatropha oil. Hence, the objective of this study was to assess a conversion path for the valorization of castor and jatropha seeds. The results showed the maximum extraction of castor oil at 90 °C, 2 rpm, and 6 mm nozzle, achieving a yield of 36.97% and for jatropha oil at 100 °C, 1.5 rpm, and 10 mm nozzle, achieving a yield of 20.11%. The acid value and cloud point of castor and jatropha oil were 0.797 and 23.44 mg KOH/g, 10±1 °C and 12±0.55 °C, respectively; while the pour point was -3 °C for both. The acid value and cloud point for biodiesels ranged from 0.26-0.43 mg KOH/g, and -12.50-6.10 °C, respectively. The viscosity of oils and biodiesel ranged from 0.02-1.3 P. GC-MS indicated 66.38% of methyl ricinoleate in castor biodiesel and 31.64% of methyl oleate in jatropha biodiesel. The HHV for castor and jatropha biodiesel ranged from 32.37-40.25 MJ/kg.

从种子到生物能源:蓖麻和麻疯树种子增值的转化途径

从蓖麻和麻疯树油中提取生物柴油可以使世界能源基质多样化。因此，本研究的目的是评估蓖麻和麻疯树种子增值的转化途径。结果表明，蓖麻油在90℃、2 rpm、6 mm喷嘴条件下提取率最高，为36.97%;麻疯树油在100℃、1.5 rpm、10 mm喷嘴条件下提取率最高，为20.11%。蓖麻油和麻疯树油的酸值和浊点分别为0.797和23.44 mg KOH/g，温度分别为10±1℃和12±0.55℃;而两者的倾点均为-3℃。生物柴油的酸值和浊点范围分别为0.26 ~ 0.43 mg KOH/g和-12.50 ~ 6.10°C。油和生物柴油的粘度范围为0.02 ~ 1.3 p, GC-MS分析表明蓖麻生物柴油的油酸甲酯含量为66.38%，麻疯树生物柴油的油酸甲酯含量为31.64%。蓖麻和麻疯树生物柴油的HHV值为32.37 ~ 40.25 MJ/kg。
