Sustainable reductions in energy and time requirements in fried palm oil (Borassus flabellifer) biodiesel (FPOB) production (97% yield) have been achieved in differently powered reactors viz., low-energy infrared radiation (LEIR) (0.131 kWh) and LEIR with ultrasonic-energy (LEIRUE) (0.12 kWh) in comparison with conventional heating energy (CHE: 0.664 kWh). Life cycle assessment (LCA) employing IMPACT 2002 + indicated adverse environmental impacts of energy-intensive CHE reactor generating 28.4% more respiratory organics, 67.6% augmented global warming and additional 38.3% energy utilization in comparison with the novel LEIRUE reactor. Feasibility of 2-ethylhexyl acetate (2EHA), triacetin (TA), and 5 other esters were assessed as fuel additives (FAs) for FPOB (B100) and diesel-FPOB (B10) in conventional diesel engine. The optimal 1:1 v/v mix of the two best FAs (2EHA + TA) i.e., ETA was blended in 5, 7, and 10 vol% with B10 and B100 for impact assessment. Remarkably, the best 7 vol% ETA blending could successfully diminish pour point and NOx emission by 36 ± 1% and 28 ± 1% respectively for B100. The LCA also confirmed that 7 vol% ETA (for B10 and B100) blending could manage all the impact categories ascertaining environmental sustainability. Thus, ETA can find applications as a potent FA for B100 and B10 blends.

在节能型反应堆中,从黄柏油中提炼的可持续生物柴油生产的生命周期评估:多种燃料添加剂对倾点,NOx和发动机性能的影响评估

可持续降低煎炸棕榈油(Borassus flabellifer)中的能量和时间要求)生物柴油(FPOB)的生产(97%的产率)已在不同功率的反应堆中实现,即与传统能源相比,低能红外辐射(LEIR)(0.131 kWh)和带超声能的LEIR(LEIRUE)(0.12 kWh)热能(CHE:0.664 kWh)。使用IMPACT 2002 +的生命周期评估(LCA)表明,与新型LEIRUE反应堆相比,耗能大的CHE反应堆产生了28.4%的呼吸有机物增加,67.6%的全球变暖增加和38.3%的能源利用。评估了传统柴油发动机中FPOB(B100)和柴油FPOB(B10)的燃料添加剂(FAs),评估了乙酸2-乙基己酯(2EHA),三醋精(TA)和其他5种酯的可行性。将两种最佳FA(2EHA + TA)(即ETA)的最佳1:1 v / v混合物掺入5、7 B10和B100用于影响评估的比例为10%。值得注意的是,对于B100而言,最佳的7%(体积)ETA混合可以成功地将倾点和NOx排放量分别降低36±1%和28±1%。LCA还确认,将7%(体积)的ETA(针对B10和B100)混合可以管理所有影响类别,以确定环境的可持续性。因此,ETA可以作为B100和B10混合物的有效FA找到应用。
