Synergy of blending HEFA with alternative petroleum fractions

Popis výsledku v původním jazyce

Jet fuel is the fastest-growing oil-based commodity. As it is difficult to substitute it with other energies, more attention is being paid to sustainable aviation fuels (SAFs). Hydrogenated esters and fatty acids (HEFAs) dominate SAF now. The jet fuel consumption forecasts show that the share of petroleum hydrocarbons in jet fuel will remain high until 2050. As oil consumption will decline with electromobility, the availability of straight-run kerosene for jet fuel will also decline. For this reason, the utilization of alternative petroleum fractions, such as hydrocracking kerosene (Jet HC) or hydrotreated heavy FCC naphtha (FCC HN), and their miscibility with HEFA have been studied. These components were generally blendable with HEFA. All properties were linearly dependent on the HEFA content, with the exception of the smoke point. Taking into account the Jet A-1 requirements, only Jet HC met them completely. Since the components have opposing properties, blending them has opened an application window in jet fuel, wider for blends of HEFA with Jet HC (0–68 vol% HEFA) and narrower for HEFA with FCC HN (73–81 vol% HEFA). The limitations were the low density of HEFA and the high density, the high aromatic content, the low smoke point, and the low net calorific value of FCC HN. To expand the application window of FCC HN in jet fuel, further research will focus on the hydrogenation of aromatics.
