The aim of the article is to determine the properties of fuel mixtures of Fischer-Tropsch naphtha fraction with traditional gasoline (petrol) to be able to integrate the production of advanced alternative fuel based on Fischer-Tropsch synthesis into existing fuel markets. The density, octane number, vapor pressure, cloud point, water content, sulphur content, refractive index, ASTM color, heat of combustion, and fuel composition were measured using the gas chromatography method PIONA. It was found that fuel properties of Fischer-Tropsch naphtha fraction is not much comparable to conventional gasoline (petrol) due to the high n-alkane content. This research work recommends the creation of a low-percentage mixture of 3 vol.% of FT naphtha fraction with traditional gasoline to minimize negative effects-similar to the current legislative limit of 5 vol.% of bioethanol in E5 gasoline. FT naphtha fraction as a biocomponent does not contain sulphur or polyaromatic hydrocarbons nor benzene. Waste materials can be processed by FT synthesis. Fischer-Tropsch synthesis can be considered a universal fuel-the naphtha fraction cut can be declared as a biocomponent for gasoline fuel without any further necessary catalytic upgrading.
本文的目的是确定费托石脑油馏分与传统汽油的燃料混合物的特性，以便能够将基于费托合成的先进替代燃料生产整合到现有的燃料市场中。使用气相色谱法PIONA测量了密度、辛烷值、蒸气压、浊点、含水量、硫含量、折射率、ASTM颜色、燃烧热和燃料组成。结果发现，由于正构烷烃含量高，费托石脑油馏分的燃料特性与传统汽油不太可比。这项研究工作建议将3体积%的费托石脑油馏分与传统汽油制成低百分比混合物，以尽量减少负面影响——类似于目前E5汽油中生物乙醇5体积%的法定限量。费托石脑油馏分作为一种生物组分，不含硫、多环芳烃和苯。废料可以通过费托合成进行处理。费托合成可以被视为一种通用燃料——石脑油馏分可以被宣布为汽油燃料的生物组分，无需任何进一步的必要催化升级。
