摘要:
以酯基生物柴油（biodiesel，BDO）作为原料，经连续加氢脱氧—异构等一系列工艺处理，制得烃基生物柴油（hydrocarbon-based biodiesel，HVO），用其配置D90B5H5（90%柴油+5%BDO+5%HVO）、D80B10H10（80%柴油+10%BDO+10%HVO）和D70B15H15（70%柴油+15%BDO+15%HVO）三组双生物柴油混合燃料，并以柴油作为参照，在TBD234V6型柴油机上进行燃烧试验，探究混合燃料对其燃烧过程和排放性能的影响。研究结果表明：1）柴油机燃用混合燃料时的当量燃油消耗率随双生物柴油掺混比例的增大而降低，在额定工况下，柴油机燃用D90B5H5、D80B10H10和D70H15B15的当量燃油消耗率比燃用柴油分别降低了1.0%、2.1%和2.6%。在不同负荷工况下，尽管混合燃料热值较柴油低，但其内在的含氧属性和高十六烷值更利于燃烧。2）在燃料特性的综合影响下，与燃用柴油相比，燃用D70B15H15的最高爆发压力在25%、50%、75%和100%负荷工况下分别提高了0.8%、1.3%、1.5%和1.9%，瞬时放热峰值时刻也有所提前。3）在额定工况下，与柴油相比，燃用D70B15H15的CO、HC和碳烟排放量分别降低了11.0%、9.3%和14.2%，NOx排放量上升了7.2%。综上，燃用双生物柴油混合燃料能提高燃料品质，改善柴油机的燃烧和排放性能。
Abstract:
In this paper,ester-based biodiesel (BDO) was used as raw material,and a series of processes such as continuous hydrodeoxygenation isomerization were carried out to obtain hydrocarbon-based biodiesel (HVO).Three groups of dual-biodiesel blended fuels,D90B5H5 (90% diesel + 5% BDO + 5% HVO),D80B10H10 (80% diesel + 10% BDO + 10% HVO) and D70B15H15 (70% diesel + 15% BDO + 15% HVO) were prepared respectively.Diesel was used as a reference,and combustion tests were carried out on a TBD234V6 diesel engine to explore the effects of the mixed fuels on its combustion process and emission performance.The results show that the equivalent fuel consumption of diesel engines using mixed fuels decreases with the increase of the proportion of dual-biodiesel blending.Under rated conditions,the equivalent fuel consumption of diesel engines using D90B5H5,D80B10H10 and D70H15B15 is reduced by 1.0%,2.1% and 2.6% respectively compared with that of diesel.Under various load conditions,although the calorific value of the mixed fuel is lower than that of diesel,its inherent oxygen content and high cetane number are more conducive to combustion.Under the comprehensive influence of fuel characteristics,compared with diesel,the maximum explosion pressure of D70B15H15 increased by 0.8%,1.3%,1.5% and 1.9% at 25%,5%,75% and 100% load conditions respectively,and the instantaneous heat release peak time was also advanced.Under rated conditions,compared with diesel,the CO,HC and soot emissions of D70B15H15 were reduced by 11.0%,9.3% and 14.2% respectively,and the NOx emissions increased by 7.2%.In summary,the use of dual-biodiesel blended fuel can improve the fuel quality and the combustion and emission performance of diesel engines.
