Abstract

Environmental pollutions, energy problems and other uncertainties associated with the use of fossil fuel are some reasons which constitute the quest for eco-compatible fuel substitutes. Vegetable oils (VOs) are known raw materials that will remedy the situation. Palm oil (PO) and melon oil (MO) were extracted and blended in various proportions PO:MO (0:100, 10:90, 30:70, 40:60, 50:50, 60:40, 80:20, 100:0) for biodiesel (BDS) production through the process of trans esterification using a catalyst (sodium hydroxide, NaOH). Viscosities of the blends decrease as temperature increases. Experimental information was applied to Grunberg-Nissan (d-)parameter; the range of PO50: MO50 blend (-10.629 to -8.030) showed the least negative d-parameter values at all temperatures (283K to 323K) and viscosity deviations at various temperatures range between -20 to 21. Thermodynamic studies were carried out on the blends; the randomness of the system and negligible effect of inter- and intra- bonding energies of the system were defined by the increasing negative values of Gibbs free energy of mixing (ΔGM) and zero enthalpies of mixing (ΔHM = 0). Energies of the produced BDS increase as calorific values of the blends increase (36 - 49 MJ/k) with an increase in the fractions of MO, and cloud point ranges from -1 to 0oC. The biodiesel properties were found to be comparable to the American Society for Testing and Material (ASTM) standard.

棕榈和瓜油二元共混生产生物柴油的热力学研究
与使用矿物燃料有关的环境污染、能源问题和其他不确定因素是寻求生态相容的燃料替代品的一些原因。植物油(VOs)是可以补救这种情况的已知原料。以棕榈油(PO)和瓜油(MO)为原料,在氢氧化钠(NaOH)催化下,以PO:MO(0:100、10:90、30:70、40:60、50:50、60:40、80:20、100:0)的不同比例进行反式酯化反应,制备生物柴油(BDS)。共混物的粘度随着温度的升高而降低。将实验信息应用于Grunberg-Nissan (d-)参数;PO50: MO50共混物(-10.629 ~ -8.030)在283K ~ 323K温度范围内的负d参数值最小,粘度偏差在-20 ~ 21温度范围内。对共混物进行了热力学研究;混合吉布斯自由能的负值(ΔGM)和混合零焓值(ΔHM = 0)的增大,表明体系的随机性和键间能和键内能的影响可以忽略不计。随着MO组分的增加,共混物的热值(36 ~ 49 MJ/k)的增加,生成的BDS的能量也随之增加,云点范围从-1℃到0℃。生物柴油的性能可与美国材料试验协会(ASTM)的标准相媲美。
