Preparation of PPDCs
The PPDCs were prepared by the compound of RMC-MB-NVP terpolymers and
some dispersants, such as Span (Span 40, 60, and 80), Tween (Tween 40,
60, and 80), PAEs (DMP, DEP, and DBP) and FAPE (FAPE 5, FAPE 7, and FAPE
9), in the ratios of 0:1, 1:1, 4:1, 8:1, and 1:0, respectively. Then,
the PPDCs were added into the prepared biodiesel-diesel blends and
sonicated at 30 °C for 10 min to ensure complete miscibility. Thereinto,
the biodiesel-diesel blends were configured in proportions of 20, 40,
60, 80, and 100 vol.% of biodiesels, which labelled as B20, B40, B60,
B80 and B100.
