“…9,27 Specically, the sharp improvement in cold ow properties (reductions between 6-11 C) observed in diesel blends with low hydroturpentine contents (1% v/v, i.e., 10 000 ppm) suggests that hydroturpentine would be a competitive cold ow depressant for diesel fuel, with similar performance as some commercial depressors. 28…”

“…POM has been proven to be an effective technique for observing the crystallization behavior and crystal morphology of sample fuels at low temperature (Chen et al, 2020; Yang et al, 2020). In the POM images, the crystals exert polarized reflective light and present bright white images, as well as the amorphous substances absorbed light to form black images (Chen et al, 2020; Hamada et al, 2010; Yang et al, 2020). The POM images of neat BWCO (100 vol.% BWCO), BWCO+DDCL (20 vol.% BWCO +80 vol.% DDCL), BWCO+ET + DDCL (20 vol.% BWCO +10 vol.% ET + 70 vol.% DDCL) and BWCO+ET + DDCL (20 vol.% BWCO +10 vol.% BT + 70 vol.% DDCL) blends at −15 and −20°C are shown in Figure 4.…”

The utilization and popularization of biodiesel are always limited by its poor cold flow properties. Both bio-based alcohol and diesel from direct coal liquefaction (DDCL) has potential to enhance the cold flow properties of biodiesel. In this study, ternary blends of waste cooking oil biodiesel (BWCO) with DDCL and bio-based ethanol (ET) or 1-butanol (BT) were conducted to improve the cold flow properties of biodiesel. The pour point (PP), cold filter plugging point (CFPP), and cloud point (CP) of BWCO-ET, BWCO-BT, and BWCO-DDCL binary blends, and BWCO-ET-DDCL and BWCO-BT-DDCL ternary blends were comparatively assessed. Ternary phase diagrams were also applied to analyze the blending effect of the three components on the cold flow properties of biodiesel. Results showed that both DDCL, ET, and BT can remarkably enhance the cold flow properties of BWCO. When the ternary blends contain 20 vol.% BWCO and less than 40 vol.% ET or BT, DDCL together with ET or BT exerted positive effects on enhancing the low-temperature flow properties of BWCO, especially on the CP and CFPP. For ternary blends in 20:10:70 blending ratio, BWCO-BT-DDCL exhibited the lowest PP, CFPP, and CP of À23, À19, and À17 C, respectively. The crystallization behavior and crystal morphology of blended fuels are also observed via a polarizing optical microscope, and find that DDCL together with BT in biodiesel can effectively retard the aggregation of large crystals and inhibit crystals growth.

High-efficiency pour point depressants (PPDs) for diesel fuel were obtained using a series of tetradecyl methacrylate-N-α-methacrylamide copolymers (C 14 MC-NMLR) with different molar ratios synthesized through radical polymerization of tetradecyl methacrylate (C 14 MC) and various forms of N-α-methacrylamide (NMLR, R = -phenyl, -naphthyl, -cyclohexyl, -14a, -16a, -18a). The copolymers were characterized by Fourier transform infrared spectroscopy, 1 H nuclear magnetic resonance, and thermogravimetric analysis. Results showed that diesel treated with C 14 MC-NML-phenyl (9:1) and C 14 MC-NML-14a (6:1) presented better cold flow properties at 2000 ppm, and the reductions in cold filter-plug point (ΔCFPP) and solid point (ΔSP) were (23 and 10 °C) and (22 and 11 °C) at 2000 ppm, respectively. The depressive effects further improved after compounding. When they were combined at a 1:4 mass ratio, PPDC-6 presented the best depressive effects, and the ΔCFPP and ΔSP reached 25 and 11 °C at 1000 ppm dosage and 28 and 15 °C at 2000 ppm dosage, respectively. Additionally, the crystallization behavior and crystal morphology of each treated diesel were explored.
