“…The boiling temperature and flash point of oil samples E1 (100% PE), E2 (100% PP) and E3 (100% PS) are shown in Table . From the distillation curve data, the boiling temperature values were calculated and are found to vary over a wide range (i.e., from 423 to 623 K). The oil obtained from 100% PS (E6) is the one with the lowest boiling temperature value, 459.03 K, while the oil obtained from 100% PE (E1) has the highest value, 557.89 K; these values are similar to those obtained by authors such as Walendziewski …”

Production of an Alternative Fuel by Pyrolysis of Plastic Wastes Mixtures

et al. 2020

This paper tries to obtain an alternative liquid fuel from plastic waste from the fraction not collected selectively, through a pyrolysis process. The fuels obtained from three plastic wastes, polyethylene (PE), polypropylene (PP), and polystyrene (PS), and from binary mixtures (PE−PP and PE−PS) and a tertiary mixture (PE−PP−PS) were characterized. These plastic wastes are the most abundant in the fraction not collected selectively. Concretely, the polyethylene film comprises 43% of total plastic of this fraction. The plastic mixtures have been chosen according to the composition of the plastic in this fraction. Liquid fuel from the polyethylene film had very similar characteristics to commercial fuels, in particular, diesel, but had a very high viscosity and a waxy appearance. Liquid fuel from polystyrene had a very fluid appearance, but possessed a large number of aromatic compounds, being useful for the synthesis of basic chemical products. The liquid obtained from polypropylene has a semiwaxy appearance and a large number of olefins. Finally, the mixtures of these wastes produced intermediate characteristics. The viscosity and waxy aspect increases when the quantity of polyethylene increases, while fluidity and the quantity of aromatic compounds also increase when the quantity of polystyrene increases.

“…Thus, the reaction mixture temperature of 450 °C was proposed to be economically suitable for further experimentation, yielding approximately 67 percent liquid biofuel in 15 min. Carbon dioxide, carbon monoxides, and hydrocarbon compounds C1-C5 make up the resultant gas 49 . Although its proportion may have reached close to 30%, the current study focused on the liquid product and the prospect of employing it as a bio jet fuel.…”

The current work investigated the preparation of Nano-particles of Co/Zn Al2O4 as a catalyst via co-precipitation method. Several analyses, including BET, XRD, HRTEM, EDX, SEM, and FTIR, were used to characterize it. The analysis revealed that the prepared catalyst had an average surface area of 69.20 m2/g, a cross-sectional area of 16.2 m2/molecule, an average particle size of approximately 28 nm, and a pore size of 0.22 cm3/g. The prepared catalyst was used in a bio fuel synthesis process via thermo-catalytic cracking of waste cooking oil (WCO) in a single step batch reactor. Catalyst loading was tested with different weight percentage of 1.5%, 2%, and 2.5%. The pilot study revealed that the best conditions for optimizing bio jet fuel yield were 400 °C, a catalyst loading of 2%, and a reaction time of 30 min.The optimal cut-off from the distillation process of crude liquid bio fuel product which represents a fraction of bio-jet fuel was in the range from 150 to 240 °C.

“…This bio-oil can be used directly as a fuel or can be fractionated to obtain purified hydrocarbons in the range of gasoline and diesel. These biofuels have been compared to fossil fuels and the results show partial agreement with fossil fuel specifications [7,21,22].…”

Pyrolysis of triglycerides based on biomass was used at large scale for fuels supply during the world wars. For this study, the bio-oil produced from waste fish oil pyrolysis was fractioned in a distillation column to produce a light fraction cut in the range of gasoline. This biofuel was tested in a motorcycle engine to measure its performance in terms of torque and analysing its exhaust gas composition. The emissions were assessed by exploring the combustion of a fossil gasoline without additives and with blends of bio-gasoline, BG20 and BG30 fuels, meaning 20 and 30% of bio-gasoline in fossil gasoline, respectively. Results allowed the identification of the torque and emission gases combinations for each fuel type and the determination that as the percentage of bio-gasoline in the gasoline is increased, the concentration of CO2, CH4, C2H6, C3H8 decreased in direct relation to the engine rotation. The results show that bio-gasoline can be used as an additive of fossil gasoline with gains of performance in terms of torque and lower concentration of CO2 in the emissions. The torque increased from 3.5 to 3.7 N.m and from 4.0 to 5.0 N.m at fifth gear and at 2000 and 4000 rpm, respectively.
