Abstract

Different alkyl chain length of levulinate esters were compounded with 0# diesel fuels, and Hildebrand solubility parameters were introduced to verify the mutual solubility, and then the physicochemical properties of the formulated fuels, such as closed-end flash point, kinematic viscosity, cold filtration point and oxidative stability were tested and studied. The results show that the blended fuels of longer the alkyl chain ester combined with 0# diesel fuel are more stable, the fuels of shorter alkyl chain ester and 0# diesel fuel are easy to delaminate at low temperature. The low temperature fluidity, spraying atomization, transportation and storage safety, oxidation stability of the compounded fuel are significantly improved.
