“…James et al, found that the order of boiling point volume content of the biocrude oil prepared from different raw materials corresponds to the order of average molecular weight and long-branched aliphatic molecular content ratio identified by 13C nuclear magnetic resonance (NMR) spectroscopy [34]. Previous studies have also found that the molecular weight of the biocrude oil or bio-oil will increase during long-term storage [13,15,35]. The increase in high-molecular-weight and long-branched aliphatic groups reflects the polymerization and condensation reactions during storage, which will cause an increase in viscosity [36].…”

The stability of biocrude oil is a significant challenge for its storage, transportation, and refining. In this investigation, the thermal and oxidative stability of Spirulina-biocrude oil derived from a plug-flow continuous hydrothermal reactor was systematically studied. The biocrude oil was stored at three temperatures to simulate the winter (4 °C), spring and autumn (15 °C), and summer (35 °C) seasons, and in two atmospheres (air and N2) to simulate the conditions of a storage tank being sealed or kept open. Results demonstrated that the physicochemical properties of biocrude oil were highly influenced by the storage environment. The viscosity of biocrude oil increased with increasing storage temperature and time. The maximum viscosity (17,577 mPa·s) was observed when biocrude oil was stored at 35 °C and in an air condition over 84 days, 145% higher than fresh biocrude oil (7164.2 mPa·s). The viscosity increased by 10.9% when biocrude oil was sorted at 4 °C in an N2 atmosphere after being stored for 28 days. After long-term storage, biocrude oil still exhibited comparable characteristics to petroleum, with a slight decrease in HHV (31.36–33.97 MJ·kg−1) and the nitrogen-to-carbon ratio (0.087–0.092). This study indicated that the viscosity and HHV of the biocrude oil derived from a continuous reactor stored at 4 °C in an N2 atmosphere condition remained relatively unchanged, which enables the scheduling of oil refining production.

“…The fuel properties of biodiesel products derived from lard oil and compared with palm oil catalyzed by using CaO_FWC catalyst were presented in Table 3. The European standard test method (EN-14214) and the American Society for Testing and Material (ASTM-D6751) standard test method were applied to evaluate the physicochemical properties of the final biodiesel product following the reports of Roschat et al [26,27], Cruz-Merida et al [29], Paola et al [42], Afzal et al [43], Mohiddin et al [44], and Taghipour et al [45]. The yield of biodiesel products (% v/v) was calculated by the volume of the obtained biodiesel product divided by the volume of lard oil or palm oil as a starting material.…”

In the present work, the catalytic activity and stability of the Fresh-water Clamshells-derived CaO catalyst were investigated by the transesterification reaction of lard oil. The physicochemical properties of lard oil as a raw material for biodiesel production compared with palm oil were also studied. The obtained CaO_FWC was characterized by various analytical techniques to evaluate the physicochemical properties consisting of TGA, SEM, XRD, XRF, BET surface area, FT-IR, Hammett indicator method, and CO2-TPD. The results found that the fresh CaO_FWC showed the specific surface area, percentage of Ca element, total basic site, and basic strength of 8.293 m2g−1, 98.6 wt.%, 8.450 mmol g−1, and 15 < H_< 18.4, respectively which similar to CaO commercial grade. In addition, the fresh CaO_FWC catalyst also presented high catalytic activity that gave %FAME of lard oil more than 96.5 %. However, the CaO_FWC catalyst could only reuse 3 times with the catalytic activity slightly decreased, and %FAME remained higher than 95 %. While the stability of the CaO_FWC catalyst was tested by storage for a long time to 180 days, this experimental data suggested that the CaO_FWC catalyst could preserve for only 30 days, with the catalytic efficiency remaining similar to the fresh CaO_FWC. Furthermore, the preservation and reusability of the catalyst were also studied in terms of the kinetic rate of reaction for use as a database to optimize the reaction conditions. Finally, the fuel properties of biodiesel products derived from lard oil and palm oil as raw materials and catalyzed by CaO_FWC catalyst met the specified standards both of EN-14214 and ASTM-D6751. Therefore, all the results of this work were excellent databases for utilizing and adding value to the Fresh-water Clamshells and lard oil as biomass sources for further development and development as renewable and alternative energy in Thailand. HIGHLIGHTS The CaO catalyst obtained after calcination of the Fresh-water Clamshells has displayed excellent catalytic activity for the transesterification of lard oil with biodiesel conversion and FAME yield obtained under optimal conditions up to 96.86 % The Fresh-water Clamshells could stand promising resource for low-cost catalysts to lead the way for low-cost biodiesel The kinetic data can be used to optimize the biodiesel production process GRAPHICAL ABSTRACT

“…Biomass can undergo thermochemical processes, such as pyrolysis or hydrothermal liquefaction, to produce biocrude. By subjecting biocrude to fractional distillation, it can be further upgraded to produce a biofuel that is equivalent in quality to fossil fuels. , Many oxygenated compounds (i.e., aldehydes, ketones, esters, phenols, and alcohols) are typically present in biocrude. , The presence of these polar components can significantly complicate the modeling of biocrude separation processes since not all thermodynamic models are able to adequately describe the phase behavior of highly nonideal mixtures …”

Process modeling and feasibility studies for biofuel production require accurate phase equilibria data. Binary mixtures of common biofuel compounds butan-2-one + 2-methylpropan-1-ol, butan-2-one + cyclopentanone, 2-methylpropan-1-ol + cyclopentanone, and a ternary system of all three components were studied to obtain vapor−liquid equilibrium data at atmospheric pressure. The experimental data were validated and verified thermodynamically by employing the modified McDermott−Ellis, Van Ness, and Herington methods. The binary vapor−liquid equilibrium (VLE) data were successfully correlated with the Wilson, NRTL, and UNIQUAC activity coefficient models and predicted with the PSRK model. Further, the PSRK model and NRTL with the obtained binary interaction parameter (BIP) model were applied to forecast VLE data for the ternary system of butan-2-one + 2methylpropan-1-ol + cyclopentanone. Both PSRK and NRTL models showed good accuracy in predicting the equilibrium temperature. At the same time, the PSRK model outperformed the NRTL model in predicting the composition of the vapor phase. The PSRK model was quite accurate for predicting the VLE of these biofuel components, even without any experimental data.
