直接液化柴油与间接液化柴油调和实验研究

本文提出适合煤基液化车用柴油调和的扩展虚拟纯组分法模型,在此模型基础上,以煤基液化车用柴油为主要原料,添加适量抗磨剂,进行了一系列调和实验,制备车用柴油。实验结果表明:以此方法制备的煤基液化车用柴油,优于同类石油基产品质量指标,并且降低了改进剂的使用量,从而降低生产成本。

Comparison of Coal-Based Dimethyl Ether and Diesel as Vehicle Fuels from Well to Wheel in China

With life cycle assessment(LCA) methodology,a life cycle model of coal-based vehicle fuels(CBVFs) including coal-based dimethyl ether(CBDME) and coal-based diesel(CBD) is established.Their primary energy consumption(PEC) and global warming potential(GWP) from well to wheel including feedstock extraction,fuel production,fuel consumption in vehicle and energy transportation are calculated and compared.Results show that the life cycle PEC and GWP of CBD pathway are 1.17 and 1.34 times as CBDME pathway.Based on the above results,CBDME will become a choice with great potential to replace conventional petroleum-based diesel (CPBD) in China.
