“…In the study of Reaume and Ellis, the hydroisomerization of palmitic acid catalyzed by β zeolite can effectively yield 42% branched chain products at 285 °C and 4.0 MPa, and the CP is significantly reduced by 10 °C. The yield of isomerized palm oil (deoxygenated) was 81% at 5.0 MPa and 350 °C, under hydrogen, with a synthesized Pt/SAPO11 catalyst . After the distillation of light hydrocarbons formed during hydroisomerization, a blend of 71% product and 29% deoxygenated palm oil has a cetane index of 92.4, PP of 2.8 °C, flash point of 82 °C, distillation range of 225–321 °C, and heating value of 47.3 MJ/kg .…”

To apply this technique on an industrial scale, more selective mesoporous molecular sieves can be developed that can be processed under milder operating conditions …”

Biodiesel is a mixture of fatty acid alkyl esters (FAAEs) produced by transesterification, which has been promoted as a substitute for petroleum diesel in some areas of China. However, it shows poor cold flow properties (CFPs), such as high pour point, high cloud point, and high cold filter plugging point, meaning that biodiesel would crystallize under low-temperature conditions, thus resulting in engine problems and emission issues. This review focused on the mechanisms related to the CFPs of biodiesel and outlined the factors that initialize and accelerate the crystallization process. The influence of CFPs on engine performance and pollutant emissions was also discussed. Particular emphasis was given to available methods that can improve the CFPs of biodiesel. Modifying the composition of FAAEs, changing the component ratio, and removing minor constituents are three primary directions. Every derivative method was described in detail about the characteristics, shortcomings, and what can be improved. The type and load of cloud point/pour point/cold filter plugging point cold flow improvers were compared and selected on the basis of the improvement effect of CFPs. Microemulsion is a new method that may be used to improve the CFPs of biodiesel. As a result of the variability of the biodiesel components and the complexity of each improving method on the overall fuel properties and performance, the CFP modification methods should be studied and evaluated carefully and comprehensively before being adopted in industrial applications.

“…In the literature, the most common first-generation plant oils that have been used for CDO reaction are those derived from food crops. Among the edible oils, soybean oil [20,21], palm oil [22][23][24][25], sunflower oil [26], and rapeseed oil [27][28][29][30] have been used extensively as the feedstock in producing renewable diesel (RD). However, rapeseed, sunflower, and soybean oils are generally unsuitable to be used as feedstock in the Southeast Asia region due to their low crop availability.…”

“…Thus far, the catalysts used in the HRD were mostly loaded using noble metals (such as Pd/C, Pd/γ‐Al 2 O 3 , and Pt/γ‐Al 2 O 3 ) 15,16 or sulfide metals (such as sulfide NiMo/γ‐Al 2 O 3 , and sulfide CoMo/γ‐Al 2 O 3 ) 17,18 . However, noble metal catalysts are too expensive and are easily poisoned or deactivated by the presence of water (generated under the HDO reaction) 19 .…”

Summary In this study, the main process involves the conversion of palm oil into hydro‐processed renewable diesel (HRD) over a nonsulfide catalyst. First, catalysts with different supports (γ‐Al2O3 and SAPO‐11) and metals (Ni and Mo) are compared in experiments. The results showed that 8Ni‐8Mo/γAl2O3 is the most suitable catalyst for HRD production, with the highest conversion and selectivity of 99.5% and 98.9%, respectively. The chemical kinetic reaction, conversion, and selectivity of the catalyst were analyzed through different temperatures, pressures, and H2‐to‐oil ratios to determine the optimal conditions. The regenerated catalyst through calcining showed well recovered structure and textural properties by using X‐ray diffraction, thermal gravimetric analysis, Fourier transfer infrared spectroscopy, and N2 adsorption/desorption measurements. Last but not least, the fuel components and properties of HRD were determined, include 46.8 MJ/kg of heating value, distillation temperature of 306°C, 5°C of cloud point, 81.4 of cetane number, 204°C of auto‐ignition temperature, 62°C of flash point, and 61.8 mm of smoke point, which meets the diesel specifications.
