Fuel properties of PFAD biodiesel
The fuel properties of biodiesel obtained in this work are summarized in Table 1.
It can be seen that most of its properties are in the range of fuel properties
prescribed in the latest American standards for biodiesel, except Cloud point and
pour point. PFAD mainly consists of saturated FFA (>49 wt%) which results in
high values of pour point of PFAD biodiesel. However, a blend of diesel and
PFAD biodiesel is possible in practice (Chongkhong et al. 2007).
