In the present study, production of biodiesel from biomass containing free fatty acids has been evaluated through electrolysis method as a novel efficient technique, in absence and presence of alkaline and acidic catalysts at mild operating condition. The impact of operating parameters such as voltage (10-30 V/cm), reaction time (1-3 h), methanol to oil molar ratio (10:1-40:1), acetone to methanol molar ratio (0:1-0.5:1), NaCl concentration (0-0.045 M) and catalyst type and loading on the process performance have been investigated in term of biodiesel production yield. The achieved results indicate that the biodiesel production yield using electrolysis method is about 42% at voltage of 20 V/cm, reaction time of 2 h, NaCl concentration of 0.015 M, methanol to oil molar ratio of 20:1, acetone to methanol molar ratio of 0.25:1 and without presence of catalyst, whereas it is improved to 52% and 95% in the presence of 5.6 wt.% of KOH and 13 wt.% of H₂SO₄ as catalyst, respectively. The determined physicochemical properties of the synthesized biodiesel via electrolysis method incorporating density, kinematic viscosity, cetane index, Iodine value and cloud point properties satisfy the main fuel standard criteria. The cetane index of synthesized biodiesel using electrolysis method is 57.3.

在本研究中，在不存在和存在碱性和酸性催化剂的情况下，通过电解方法已通过电解方法评估了从含有游离脂肪酸的生物质生产生物柴油的可行性。电压（10-30 V / cm），反应时间（1-3 h），甲醇与油的摩尔比（10：1-40：1），丙酮与甲醇的摩尔比（0：1）等操作参数的影响-0.5：1），NaCl浓度（0-0.045 M）以及催化剂类型和负载对工艺性能的影响已根据生物柴油的产量进行了研究。所获得的结果表明，在20 V / cm的电压，2 h的反应时间，0.015 M的NaCl浓度，20：1的甲醇与油的摩尔比，丙酮与甲醇的摩尔比的条件下，采用电解方法生产生物柴油的产率约为42％。比率0.25：₂ SO ₄分别作为催化剂。通过电解方法测定的合成生物柴油的理化性质（包括密度，运动粘度，十六烷指数，碘值和浊点性质）满足主要燃料标准。电解法合成生物柴油的十六烷指数为57.3。
