“…All GTL blends were supplied by Shell Global Solutions (London, UK), with the associated molecular formulas based on two-dimensional gas chromatography. Although the blends were delivered "as is", further information can be found in complementing research publications, prepared by other members of the ECATS Virtual Fuel Centre [24][25][26].

“…The work was part of a larger effort to investigate the applicability of fuels that can be processed to look like kerosene, as practical alternatives to fossil fuels by the Virtual Fuel Centre of the Environmentally Compatible Air Transport System project (ECATS) [24][25][26]. Aiming to contribute to the assessment of compatibility of the spray characteristics of alternative fuel blends, the objective of the present work was to evaluate the relevant physical properties including surface tension, kinematic viscosity and density, and investigate their effect on the atomization process, comparing the resulting spray properties with those of the reference Jet A-1 fuel spray.…”

Abstract:The compatibility of spray characteristics of alternative fuel blends, in relation to currently used Jet A-1 fuel, has been assessed experimentally. Tested blends were selected based on a narrow cut of paraffins, mixed with appropriately selected aromatics and naphthenes. Relevant physical properties including the density, viscosity, and surface tension were estimated first. The jet spray was produced using a single fluid, generic nozzle at operating pressures 5-11 bars. The atomization characteristics were assessed through measurements of droplet velocity field and droplet size, using phase Doppler anemometry. The physical properties varied within 10% of the reference fuel values. The spray results indicate that all tested blends produced similar atomized jets and droplet sizes, although observed differences may influence the implementation of combustion schemes which require precise control of the flow pattern.

“…These studies are the basis of the wide application of coal‐based F‐T fuels. Due to the characteristics of sulfur‐free and few aromatic hydrocarbons, the fundamental combustion characteristics and chemical reaction mechanism of coal‐based F‐T fuels have been widely investigated as potential clean energy 13,14 . Sung et al 15,16 experimentally investigated the autoignition characteristics, laminar flame speeds, and extinction stretch rates of the F‐T fuel S‐8 and conventional aviation kerosene Jet‐A.…”

“…They reported that the F‐T fuel provides fewer emissions of NOx and soot than Jet‐A1. Keramiotis et al 14 experimentally measured the combustion products of four F‐T fuels in a laboratory‐scale combustor and analyzed the influence of the component class in the F‐T fuel on the combustion product. Novick et al 21 investigated the combustion performance and emissions of the F‐T fuel using the full‐scale combustor, while Rollbuhler et al 22 utilized the flame tube combustors.…”

Based on the analysis of the combustion process of liquid fuel in the gas turbine combustor, we suggest that a comprehensive surrogate fuel should be developed according to the basic physical and chemical properties that affect the diffusion combustion process. The present study took the carbon-hydrogen mole ratio, molar weight, density, viscosity, surface tension, initial boiling point, and lower heating value, as the target properties. The optimal direction method was utilized to obtain the mixture composition ratio which has the minimum deviation on the basic physical and chemical properties compared with the Fischer-Tropsch (F-T) fuel. This mixture, taken as the comprehensive surrogate fuel of the F-T fuel, was composed of 15% n-decane, 67% n-tetradecane, 13% iso-octane, and 5% methylcyclohexane in mole fraction. Further experiments were conducted to investigate the pollutant emissions of the F-T fuel and the surrogate fuel in a gas turbine combustor. The experimental results showed that the surrogate fuel can well predict the EI(CO) and EI(NOx) of the F-T fuel in the turbine combustor, and the difference in EI(UHC) is mainly influenced by the fuel evaporation property.

“…Paying more attention to environmental issues inclines to searching the alternative fuels, which could supersede fossil fuels. In many research activities conducted in technical scale, pilot and industrial scales there is suggested to replace diesel oil or heating oil from petroleum by liquid fuels like: bioethanol, biodiesel, butanol, water-oil emulsions and others (Marmentini Vivas & Zanoelo, 2011;Nigam & Singh, 2011;Chelemuge, Yoshikawa, Takeshita & Fujiwara, 2012;Ghorbani & Bazooyar, 2012;May-Carle et al, 2012;Sáez, Flores-Maradiaga & Toledo, 2012;Keramiotis, Zannis, Skevis & Founti, 2013;Lazaroiu et al, 2018;Plante et al, 2019). The main objective of the research is to achieve a stability of combustion process and a high heat capacity at the lowest possible pollution emission into the atmosphere.…”

The results of the research on energy usage of the fatty acids distillation residue are presented. Distillation residue constitutes a material of biogenic origin, which is created only as a result of physical processing of animal fats without using additional chemicals. This material exhibits similar physicochemical properties as the heavy heating oil and may be its substitute. Industrial comparative tests of combusting of distillation residue and also of the heavy heating oil in an oil boiler were conducted. The research was conducted at the rated and minimum capacities of the boiler. It has been stated that combusting of the distillation residue of the fatty acids in a tested oil boiler does not bring about any technological difficulties. No threat of the elevated emission of pollutants into the atmosphere was exhibited. Installation of the boiler fulfill all emission standards required for combustion of the liquid fuels. Combustion of fatty acids distillation residue contributes to the reduction of the previous emission of pollutants from burning of the heavy fuel oil, significantly in scope of SO2.
