“…The CP, CFPP and PP of DDCL reached -41 degC, -49 degC and -62 degC, respectively [15]. These results are well consistent with the results of previous reports [19,20]. Similarly, the melting point of ethanol (ET) and 1-butanol (BT) had lower values of -114 degC and -89 degC, respectively.…”

“…Diesel from direct coal liquefaction (DDCL) is a value-added diesel fuel that is directly transformed from solid coal via hydrogenation liquefaction reaction under high temperature, high pressure, and suitable catalyst [15,18]. In comparison, DDCL has more excellent low-temperature flow properties than petroleum diesel (PD), and it is a good substitute for enhancing the low-temperature performance of biodiesel in coal-rich countries like China [15,19,20].…”

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.

“…It is an eco‐friendly liquid fuel because it is biodegradable and less harmful to the environment (Altaie et al, 2015; Chiu et al, 2004; Moser and Vaughn, 2010; Vedharaj et al, 2014). The use of biodiesel from waste cooking oil (BWCO) as engine fuel can reduce the consumption of petroleum‐based diesel, thereby reducing waste oil emissions and improving the environment (Cao et al, 2014b; Wang et al, 2015; Xue et al, 2016a). However, the poor cold flow properties lead to the quickly gel or solidification of biodiesel in the fuel tanks at low temperature, which eventually affect the use of biodiesel fuels in the diesel engine (Feng et al, 2014; Moser, 2014b; Xue et al, 2016b; Zheng et al, 2014).…”

Poor cold flow property is a major issue that hinders the application of biodiesel‐diesel blends. In this work, a series of methacrylate‐benzyl methacrylate‐N‐vinyl‐2‐pyrrolidone terpolymers (RMC‐MB‐NVP, R = C12, C14, C16, C18) was synthesized and used as the pour point depressants (PPD) for waste cooking oil biodiesel blends. To further improve their depressive effects, dispersants, including Tween (40, 60, and 80), Span (40, 60, and 80), phthalic acid esters (PAE), and fatty alcohol polyoxyethylene ether (FAPE; FAPE 5, FAPE 7, and FAPE 9), were optimized and combined with the C14MC‐MB‐NVP terpolymers. The effects of C14MC‐MB‐NVP terpolymers and combined PPD (PPDC) on the cloud point (CP), cold filter‐plugging point (CFPP), and pour point (PP) of biodiesel blends were studied. Here, results showed that the presence of dispersants can efficiently enhance the solubility and dispersibility of polymeric PPD in biodiesel blends; thus, the PPDC presents better depressive effects. Among them, C16MC‐MB‐NVP (5:1:1) combined with FAPE 7 dispersant at 4:1 mass ratio (PPDC‐FAPE 7) showed the best synergistic effect, and the CP, CFPP, and PP of B20 treated with 2000 ppm PPDC‐FAPE 7 decreased by 4, 10, and 19 °C, respectively. Moreover, differential scanning calorimetry, polarizing optical microscope, and rheological analyses were performed to rationalize the action mechanism of these PPD and dispersants in biodiesel blends.

“…Vigorously developing of biodiesel has great strategic significance for solving the shortage of petroleum resources, reducing environmental pollution and the greenhouse effect, and ensuring national energy safety [10]. As an alternative fuel for petrochemical diesel, biodiesel has attracted wide attention from all over the world, and large-scale production has been formed in European and American countries [11]. The economic feasibility analysis of biodiesel [12,13], the selection of raw materials, the optimization of production process, and the research of biodiesel combustion emissions have been reported at home and abroad [14][15][16][17].…”

The uniform design method was used to screen the solidifying point depressing effects of 18 traditional diesel cold flow improvers on biodiesel derived from waste cooking oil. The cold flow improvers with good effects were selected for orthogonal optimization. Finally, the mixed cold flow improver (CFI) with the best depressing effect was selected to explore its depressing mechanism for biodiesel. The results show that the typical CFIs such as A132, A146, 10-320, 10-330, A-4, CS-1, AH-BSFH, Haote, T1804D, and HL21 all have a certain solidifying point depressing effect on biodiesel, while other cold flow improvers had no obvious effect. Amongst them, 10-330 (PMA polymer) and AH-BSFH (EVA polymer) had better solidifying point depressing effects over others, both of which reduced the solidifying point (SP) of biodiesel by 4 °C and the cold filter plugging point (CFPP) by 2 °C and 3 °C, respectively. From the orthogonal mixing experiment, it can be seen that the combination of 10-330 and AH-BSFH at a mass ratio of 1:8 had the best depressing effect, reducing the solidifying point and cold filter plugging point of biodiesel by 5 °C and 3 °C, respectively. Orthogonal analysis showed that when used in combination, AH-BSFH had a greater impact on the solidifying point, while the ratio of the combination had a greater impact on the cold filter plugging point.
