“…For example, biodiesel derived from PME has a cloud point that ranges from 10 C to 20 C, which may cause trouble in cold seasons. Kleinová et al 154 used palm oil based biodiesel and conrmed that the cold ow behavior of FAME/FAEE is one of 34 reported that diesel engine start ability can be deteriorated at under-zero ambient temperature, which also creates problems of fuel starvation and operability when solidied materials clog fuel lines and lters due to the crystallization of saturated FAME components. When ambient temperature decreases, additional solids are created.…”

7Biodiesel, which comprises fatty acid esters, is derived from different sources, such as vegetable 8 oils from palm, sunflower, soybean, canola, jatropha, and cottonseed, animal fats, and waste 9 cooking oil. Biodiesel is considered as an alternative fuel for diesel engine. However, biodiesel 10 has poor cold flow behavior (i.e., high cloud point & pour point) and oxidation stability 11 compared with petroleum diesel because of the presence of saturated and unsaturated fatty acid 12 esters. Consequently, the performance of biodiesel during cold weather is affected. When 13 biodiesel is oxidized, the subsequent dregs can adversely affect the performance of the fuel 14 system as well as clog the fuel filter, fuel lines, and injector. This phenomenon results in start-up 15 and operability problems. Cold flow behavior is usually assessed through the pour point (PP), 16 cloud point (CP), and cold filter plugging point (CFPP). Earlier studies on cold flow focused on 17 reducing the devastating effect of poor cold flow problems, such as lowering the PP, CP, and 18 CFPP of biodiesel. This present paper provides an overview of the cold flow behavior and 19 oxidation stability of biodiesel, as well as their effect on the engine operation system. The 20 improvements on the behavior of cold flow of biodiesel are also discussed.21

“…There are different commercial additives for diesel and their blends with biodiesel, but for the additives to become effective, a much higher concentration is needed than the one used in this work . However, this paper presents PP reductions for palm oil methyl esters and their blends significantly better than those found in the literature …”

Biodiesel is a fuel that can be originated from different raw materials. However, even a good quality biodiesel has its properties strongly dependent upon its fatty acid profile. For instance, samples with a high content of saturated fatty acids may present poor cold flow properties, meaning that they tend to solidify under low temperatures. In this work, we propose to synthesize polymer additives and apply them as cold flow improvers for palm methyl esters (biodiesel) and their blends with petrodiesel. The synthetic additives were evaluated at different concentrations to assess their effect on the pour point (PP) of the resulting neat or blended biofuel. By using 1000 ppm of poly(dodecyl acrylate‐co‐tetradecyl methacrylate), it was possible to decrease the PP of B5 (5 vol.% biodiesel + 95 vol.% diesel) and B20 (20 vol.% biodiesel + 80 vol.% diesel) to −35 °C and −14 °C, respectively, which allowed the use of these blends in regions where their flow properties would eventually be prohibitive. However, the performance of the additive on the neat fuel (B100) was negligible.

“…However, different plant oils produce biodiesel with different chemical compositions; and thus, blends of various oils are required to produce desirable products. The process of transesterification produces monoglycerides (usually glycerine) as a by-product which largely functions as a feedstock for cosmetics (AMEC 2007;Kleinová et al, 2007). The production of bioethanol is carried out through some edible plant material such as sugarcane, sugar beet and corn kernels, since they can be easily decomposed to glucose which further can be fermented to ethanol through the microbes like yeasts (e.g.…”
