Advanced Biofuels Based on Fischer–Tropsch Synthesis for Applications in Diesel Engines

Abstract

This paper focuses on the evaluation of the fuel properties of Fischer–Tropsch diesel blends with conventional diesel. Incorporating this advanced fuel into conventional diesel production will enable the use of waste materials and non-food materials as resources, while contributing to a reduction in dependence on crude oil. To evaluate the suitability of using Fischer–Tropsch diesel, cetane number, cetane index, CFPP, density, flash point, heat of combustion, lubricity, viscosity, distillation curve, and fuel composition ratios using multidimensional GC × GC-TOFMS for different blends were measured. It was found that the fuel properties of the blended fuel are comparable to conventional diesel and even outperform conventional fuel in some parameters. All measurements were performed according to current standards, thus ensuring the repeatability of measurements for other research groups or the private sector.

Long-Term Coprocessing of Used Cooking Oils with Refinery Petroleum Fractions: A Comprehensive Study of Catalyst Activity and Biofuel Production Effects

“…It can be expected that larger changes in the behavior of products with UCO content would only occur when additives are used, for example, to improve the cold flow properties of diesel fuel intended for transitional (class D) and winter (class F) use. However, it should be noted that the worsening trend of low-temperature properties is quite noticeable here and confirms this issue of biofuels …”

Correlation between the Molecular Structure and Viscosity Index of CTL Base Oils Based on Ridge Regression

“…The global distribution of energy mix and the expanding demand for high-performance lubricants have driven the development of coal-to-liquid (CTL), gas-to-liquid (GTL), and biomass-to-liquid (BTL) technologies. 1 − 4 In China, where coal mining resources are extensive, CTL base oil is a promising alternative to existing group II and III base oils. It is technically a lubricant component for machines and engines composed of straight-chain alkanes.…”

“…Pure synthetic CTL base oils, which have a high VI, are identified as group III base oils due to the use of traditional refining technologies such as hydrocracking and isomeric dewaxing. 4 , 7 Base oil properties such as VI, pour point, density, flash point, evaporation loss, and rotary pressure vessel oxidation test (RPVOT) affect the lubricating performance and service life of the lubricant.…”
