ABSTRACT

The physical properties of direct sugar to hydrocarbon diesel (DSH-76) and several binary mixtures of n-hexadecane and 2,2,4,6,6-pentamethylheptane were measured in this work. The density and viscosity were measured at temperatures ranging from (293.15 to 393.15) K, and the pure component values fell within the range of previously reported values. Speed of sound data at temperatures ranging from (293.15 to 323.15) K increased from (1089 to 1357) m*s 1. The bulk modulus was calculated from the density and speed of sound data, and its values ranged from (858 to 1425) MPa. Flash point values ranged from (318 to 408) K, and the surface tension values ranged from (21.8 to 27.3) mN*m 1. The values of density, viscosity, speed of sound, bulk modulus, flash point (378 K), and surface tension (25.0 mN*m 1) for the DSH-76 fell within the range of values measured for the binary mixtures of n-hexadecane and 2,2,4,6,6-pentamethylheptane. These data suggest that a binary mixture of n-hexadecane and 2,2,4,6,6-pentamethylheptane may be a suitable surrogate for renewable fuels such as DSH-76.
