Abstract Biofuel has benefits of reduction in CO2 and engine exhaust emissions, so it has been attracting more attention in the past few decades. In this study, the partial oxidation reforming of biodiesel (fatty acid methyl esters, hereafter, FAME) and a new generation renewable hydrotreated vegetable oil (HVO) are evaluated using a thermodynamic analysis and an experimental investigation. The thermodynamic analysis is used to evaluate the effect of the O2/FAME and O2/HVO molar ratios on hydrogen-rich syngas production. The results show that under the best operating conditions at 800 °C and an O2/FAME molar ratio of 10, the concentration of the H2 is 21.96%, and the syngas yield is 45.50%; at an O2/HVO molar ratio of 10, the concentration of H2 is 23.01%, and the syngas yield is 45.14%. In the FAME experimental results, when the air to fuel ratio is 4.70, the H2 concentration is 18.80%, the CO concentration is 22.87%, and the reforming efficiency is 72.80%. Moreover, for HVO reforming under the air to fuel ratio of 6.30, the H2 concentration is 17.65%; the CO concentration is 17.67%, and the reforming efficiency is 62.87%. Because the composition of HVO is more complex than that of FAME, the reforming efficiency for HVO is lower than that for FAME.

生物柴油和加氢植物油部分氧化重整生产富氢合成气的热力学分析及实验研究

摘要 生物燃料具有减少CO2 和减少发动机尾气排放的优点，因此在过去的几十年中受到越来越多的关注。在这项研究中，使用热力学分析和实验研究评估了生物柴油（脂肪酸甲酯，以下简称 FAME）和新一代可再生加氢处理植物油 (HVO) 的部分氧化重整。热力学分析用于评估 O2/FAME 和 O2/HVO 摩尔比对富氢合成气生产的影响。结果表明，在800℃、O2/FAME摩尔比为10的最佳操作条件下，H2浓度为21.96%，合成气收率为45.50%；在O2/HVO摩尔比为10时，H2浓度为23.01%，合成气收率为45.14%。在 FAME 实验结果中，空燃比为4.70时，H2浓度为18.80%，CO浓度为22.87%，重整效率为72.80%。此外，空燃比为6.30的HVO重整，H2浓度为17.65%；CO浓度为17.67%，重整效率为62.87%。由于HVO的组成比FAME复杂，因此HVO的重整效率低于FAME。
