Abstract:
In
this research, biodiesel samples of different percentages of blend
biodiesel (Palestinian biodiesel prepared from waste oil) and
petro-diesel were studied. The density, refractive index, flash point
and viscosity of the samples were measured.
The
flash points were measured as a function of percentage of biodiesel,
the results emphasized that the flash points increase as the percentage
of biodiesel increases in the sample. Two equations were proposed to
obtain more suitable prediction of the flash point. The values of flash
points of biodiesel were compared with the standard value of flash point
of biodiesel. The comparison shows that samples contain more than 40%
biodiesel coincide with standard values.
The
values of kinematic viscosity of biodiesel were compared with the
Palestinian standard value of biodiesel. The comparison shows that
samples contain less than 72% biodiesel coincide with standard value.
Taking into consideration results of kinematic viscosity and flash point
one can suggest percentage 71% of biodiesel and 29% petro-diesel as the
best percentage that the two materials can be mixed and the flash point
115.3 ºC according the Palestinian standards.
