Uncontrolled emissions, massive price increases, and other factors encourage searching for a suitable diesel engine fuel alternative. In its processed form, vegetable oil biodiesel is an appealing green alternative fuel for compression ignition engines. Vegetable oil esters have qualities comparable to those of standard diesel fuel. As a result, biodiesel may be utilized to run a diesel engine without any further alterations. This article analyses the potential of Phoenix sylvestris oil, which may be found in forest belts across the globe, as a viable feedstock for biodiesel extraction. Phoenix sylvestris oil is found to be abundant in different forest belts worldwide. The free fatty acid must first be transformed into esters using catalytic acid esterification before proceeding to alkaline catalytic esterification. The molar ratio (6:1), catalyst concentration (1 wt%), reaction temperature (60 °C), and reaction time (2 h) have all been optimized for biodiesel extraction. Biodiesel produced had characteristics that were similar to standard biodiesel specifications. The biodiesel yield from Phoenix sylvestris oil was 92.3% under optimum conditions. The experimental results revealed that the Phoenix sylvestris oil biodiesel performed better than neat Phoenix sylvestris oil and its blends. Phoenix sylvestris oil blend produced better brake thermal efficiency with lower smoke, hydrocarbon, and CO emissions. The biodiesel produced from non-edible Phoenix sylvestris oil has the potential to be employed as a viable alternative to diesel fuel.
不受控制的排放、大幅价格上涨以及其他因素促使人们寻找合适的柴油发动机燃料替代品。植物油生物柴油经过加工后,是一种适用于压燃式发动机的具有吸引力的绿色替代燃料。植物油酯具有与标准柴油燃料相当的品质。因此,生物柴油无需进一步改装即可用于驱动柴油发动机。本文分析了在全球森林带中都能找到的海枣油作为生物柴油提取可行原料的潜力。研究发现,海枣油在全球不同森林带中储量丰富。在进行碱性催化酯化之前,必须先通过催化酸酯化将游离脂肪酸转化为酯。生物柴油提取的摩尔比(6:1)、催化剂浓度(1 wt%)、反应温度(60°C)和反应时间(2小时)均已优化。所生产的生物柴油具有与标准生物柴油规格相似的特性。在最佳条件下,海枣油的生物柴油产率为92.3%。实验结果表明,海枣油生物柴油的性能优于纯海枣油及其混合物。海枣油混合物产生了更好的制动热效率,同时具有更低的烟雾、碳氢化合物和一氧化碳排放。由不可食用的海枣油生产的生物柴油有潜力作为柴油燃料的可行替代品。
