能源需求的增长和有限的化石燃料资源导致植物油和动物脂肪或其衍生物等可再生能源的发展。本文研究了废鱼脂在催化剂存在下热解制取生物柴油的价值。结果，燃料经历良好的燃烧，因此在性能和排放减少方面有显著的改进。纯生物燃料的制动热效率在80%负荷下为32.4%，与纯柴油（29.98%）相比是非常高的。纯生物燃料的燃烧持续期和着火延迟期由于生物燃料的高氧含量和高十六烷值而降低。在柴油发动机中使用纯生物燃料的主要问题是在所有负荷下的高NOx排放。在80%负荷下，柴油与生物燃料的最佳混合物B80D20将NOx排放量从917ppm显著降低到889ppm。有一个轻微的降低制动器的热效率和增加微粒排放与此混合。结果表明，在柴油中添加少量生物质燃料可显著降低NOx排放，接近纯生物质燃料的性能。
The growth of energy demand and limited fossil fuel resources lead to renewable energy development such as vegetable oils and animal fats or their derivatives. In the present work, the valuation of waste fish fat by the pyrolysis technique with the presence of catalyst to produce biofuel for diesel engines. As a result, fuel undergoes good combustion and hence there is a significant improvement in performance and reduction in emissions. The brake thermal efficiency of neat biofuel is 32.4% at 80% load which is very high compared to neat diesel (29.98%). The combustion duration and ignition delay are decreased with neat biofuel due to high oxygen content and high cetane number of biofuel. The main problem with the use of neat biofuel in diesel engine is high NOxemissions at all loads. Addition of diesel with biofuel reduces the NOxemissions significantly from 917ppm to 889ppm at 80% load with an optimum blend of B80D20. There is a slight decrease in brake thermal efficiency and increase in particulate emission with this blend. The overall results show that by adding small quantity of diesel with biofuel decreases the NOxemissions significantly and approaches the performance of neat biofuel.
