Distillate of upgraded palm biodiesel was blended in different volume percentages (5, 10, 15, and 20%) with jet A-1. The mixture can be used as a replacement for petroleum Jet fuel. Physical properties of blends were measured and compared with those of jet A-1. Empirical equations were developed to predict the properties of blended fuel, including density, kinematic viscosity, freezing point, H/C ratio, and acid value. The statistical analysis indicated that the proposed equations predictions agree well with the experimental data. The predicted model shows an (R2 ) between –, indicating good fitting between the experimental data and proposed model. The distillate of upgraded palm biodiesel was miscible with the kerosene jet A-1 in all volume fractions under study 5–20%. | Empirical equations and economical study for blending biofuel with petroleum jet fuel
