“…TGA can provide a complete and reliable register of the loss of mass and phase changes thanks to the precise instrumentation used and the uniform heat transfer as the result of a sufficiently small sample size. The raw material that is submitted to pyrolysis in an industrial-scale reactor is a heterogeneous mixture of several plastics with a random distribution of the different components [16], [18]- [22]. It is complicated modeling a stochastic process, far from the deterministic nature of the TGA.…”

Introduction: This article is the product of the review “A new dynamic model of thermal degradation of polymer binary mixes submitted through pyrolysis”, developed in the University Pedagógica y Tecnológica de Colombia – UPTC-, carried out during 2020. This paper shows the validation process of a dynamic model proposed torepresent the one-step thermal degradation reaction of individual components in polymer mixtures.Problem: It is complicated to model the process of thermal degradation of polymer mixtures inside pyrolysis reactors. Inside the MPW reactor, the distribution of polymeric components in the mixture is shuffled. Objective: The objective is to validate a proposed dynamic model to represent the thermal degradation of binary polymer mixtures from the thermograms of each individual component.Methodology: A comparison is made between real data provided by TGA of binary mixes of plastic and the result of simulated thermal degradation obtained using a differential equation of the model for thermal degradation of the same plastics. Results: The simulation results showed a reasonable degree of approximation with a mean square error of less than 5%.Conclusion: The results of the simulation provide a good approximation of the loss of mass of the real samples submitted to TGA tests in the entire temperature range of the process. Consequently, it is not necessary to segment the process into sub-ranges to look for parameters in each of them.Originality: The differential equation proposed as a dynamic model for the thermal degradation of a single polymer is extended to also represent the degradation of a mixture composed of two types of plastic for the first time in this paper.Limitations: The number of samples allowed for thermogravimetric analysis was limited to five due to the institutional regulations of the UPTC for research projects attached to doctoral theses.Keywords: polymer thermal degradation, thermogravimetric analysis, dynamic model, polymer pyrolysis simulation

“…Details on the modeling of the effect of temperature on transesterification process can be found in the literature. [32][33][34] Moreover, the alcohol-to-oil molar ratio may vary, largely depending on the catalyst percentage (wt%). With a higher catalyst percentage (wt%), the molar ratio is less, and where the catalyst percentage (wt%) is less, the molar ratio is significantly higher; such as, in the methodology described by Krishnamurthy et al, 22 due to having a low catalyst percentage (0.866 wt%), the molar ratio (12.74:1) is found to be higher.…”

As dairy industries increase across Australia, the amount of dairy waste is also on the rise. Australia annually production stands at around 377 727 t of cheese, 273 425 t of milk powder and 92 698 t of butter, and it is the third largest exporter of milk. The waste produced by these industries is considered a potentially valuable resource, and an environmental pollutant if not appropriately managed. The focus of this review is to evaluate the potential of converting typical Australian dairy industry waste into sustainable energy. Five fundamental methods including transesterification, pyrolysis, anaerobic digestion, steam reforming, and hydrothermal carbonization are discussed. Their technological merits, demerits and adaptability from the perspective of Australia are examined. The properties of representative wastes are also considered for the different energy conversion processes. This review aims to highlight the potential use of dairy industry wastes as feedstock for the emerging renewable energy sector.

“…The effect of temperature at low weight percents is weaker than that at high weight percent of catalyst. This is possibly because the transesterification is a catalytic reaction and goes faster when the basic sites and the contact surface area for reaction increase [25,26].…”

A nanocatalyst of CaO supported by Fe3O4 magnetic particles was prepared by a chemical precipitation method. It was characterized by various techniques including X-ray diffraction, transmission electron microscopy (TEM), scanning electron microscopy (SEM); Fourier transforms infrared spectroscopy (FTIR), and Hammett indicator. It has been found that the catalyst consists of CaO and Fe3O4 accompanied by CaFe2O4. This composite catalyst was used for the catalytic transesterification of palm seed oil. The results revealed that the highest biodiesel yields for palm seed oil of 69.7% can be obtained under the conditions of (65 °C reaction temperature, 300 min reaction time, 20 methanol/oil molar ratio, and 10 wt.% of CaO/Fe3O4 catalyst loading). The physicochemical properties of the biodiesel produced from palm seed oil were further studied and compared with the ASTM and the EN biodiesel specifications. The results showed that the properties of the biodiesel produced comply with the international standard specifications.
