“…Lin et al recently reported the synthesis of the terpolymers of C14 or C16 n -alkyl methacrylate, benzyl methacrylate (BM) and N -vinylpyrrolidone (NVP) [ 160 ] by free-radical copolymerization on the basis of 1–20:1:1 comonomer ratios ( Scheme 8 ). Similar copolymers, based on C12, C14, C16 and C18 alkyl methacrylates, were studied by Su et al as PPDs for the blends of the waste cooking oil BD (38.4 wt% of saturated FAMEs, CP = 7 °C, PP = 5 °C) with petroleum diesel (CP = −1 °C, PP = −12 °C) [ 161 ].…”

In recent decades, biodiesel has been explored as a prospective comparable fuel to petroleum diesel for compression ignition engines. However, several drawbacks have limited the wide application of biodiesel as motor fuel, and the poor cold-flow property is one of the major problems. This problem is compounded by the diversity of the biodiesel characteristics arising from a variety of chemical compositions of biodiesel from different sources. Among the methods investigated to improve the cold-flow properties of biodiesel, the use of additives seems highly promising. Despite the significant number of publications, the potential of this method is still far from having been completely discovered or exploited. In the present review, we briefly describe the sources, chemical composition, and physico-chemical characteristics of the main types of biodiesel. Next, we discuss the examples of the use of different polymer additives for the improvement of the cold-flow characteristics of biodiesel and biodiesel/petroleum diesel blends. Additionally, we tried to assess the prospects of the polymer additives to enhance biodiesel performance. The main conclusion of this survey is that innovative and high-efficiency cold-flow improvers for biodiesel should be further developed.

“…One of the major technical obstacles that hinders the developments and application of biodiesel fuels is their poor low-temperature flow properties, which may cause blockage of the oil pipelines and filter because of the crystallization of the saturated fatty acid methyl esters with high melting points in biodiesel fuels [4][5][6][7]. Nevertheless, many methods can be used to mitigate this problem, such as modifying structures [8,9], winterization [10,11], adding pour point depressants [12][13][14], and blending with diesel [15,16].…”

“…Alcohols, such as ethanol (ET) and 1-butanol (BT), are primarily bio-based renewable energy because they are derived from the fermentation of renewable biomass [21][22][23]. Many researchers have investigated the effect of blending alcohols with biodiesel or diesel on the cold flow properties because of their relatively lower freezing points [14,24]. Hence, replacing the petrodiesel with biobased alcohols in ternary blends with biodiesel and DDCL to enhance the low-temperature flow properties of biodiesel is extremely possible.…”

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. Ternary blends of waste cooking oil biodiesel (BWCO) with DDCL and bio-based ethanol (ET) or 1-butanol (BT) for improving 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 into 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. BT and DDCL presented a better synergistic depression effect. For ternary blends in 20:10:70 blending ratio, BWCO-BT-DDCL exhibited the lowest PP, CFPP, and CP of −23 °C, −19 °C, and −17 °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.
