“…According to previous studies [21], the oil obtained from the thermal pyrolysis of the polyethylene film from the organic-rest fraction was a wax, with a high viscosity for low temperatures, while at high temperatures the oil is in a liquid state with low viscosity values. With respect to this product, the viscosity was 1000 cst at 40 • C, 115.36 cst at 50 • C and 67.50 cst at 60 • C. In addition, in this previous study, a gas chromatography with masss spectrometry (GC-MS) was performed and it was determined that the components present in the sample were mostly 1-alkenes and n-alkanes in the range C 7 to C 28 .…”

“…Plastic waste is mechanically pre-treated in the recycling plant in order to separate the different materials and facilitate subsequent recycling and baling. The samples treated in the laboratory come from the bunker corresponding to each type of plastic separated inside the plant [21]. The plastic was polyethylene film and this polyethylene film was converted into pellets to facilitate feeding to the reactor.…”

“…MCM-41, or the less acidic mesoporous SiO2-Al2O3, are also interesting options to produce liquid fuels. In previous works the thermal pyrolysis of polyethylene film plastic waste of the organic-rest fraction was studied [21], and it was determined that the characteristics of the oil were of quality for its use as a fuel, but this oil was mainly a wax. The problem of the heavy oil-waxes from the pyrolysis is their high viscosity and that they do not have a suitable use [22].…”

Currently, society is facing a great environmental problem, due to the large amount of plastic waste generated, most of which is not subjected to any type of treatment. In this work, polyethylene film waste from the non-selectively collected fraction was catalytically pyrolyzed at 500 °C, 20 °C/min for 2 h, in a discontinuous reactor using nitrogen as an inert gas stream. The main objective of this paper is to find catalysts that decrease the viscosity of the liquid fraction, since this property is quite meaningful in thermal pyrolysis. For this purpose, the three products of catalytic pyrolysis, the gaseous fraction, the solid fraction and the liquid fraction, were separated, obtaining the yield values. After that, the aspect of the liquid fraction was studied, differentiating which catalysts produced a larger quantity of waxy fraction and which ones did not. The viscosity of these samples was measured in order to confirm the catalysts that helped to obtain a less waxy fraction. The results showed that the zeolites Y and the zeolites β used in this study favor the obtaining of a compound with a smaller amount of waxes than for example catalysts such as FCC, ZSM-5 or SnCl2.

“…Higher operating temperature, long time residence heating rates with slow quenching of the waste enabled the production of syngas with raised percentages of H 2 , CO, CO 2 , and light hydrocarbons in the gas phase [12]. Pyrolysis oil comprises hydrocarbons, aromatic hydrocarbons, benzene derivatives and oxygenates [13]. Raw char can be used only after pretreatment.…”

Pyrolysis Conversion of Polymer Wastes to Noble Fuels in Conditions of the Slovak Republic

This paper deals with the pyrolysis conversion of synthetic waste materials into noble fuels, i.e., heating oils, gasoline, diesel, and carbon. The following article presents the principle and use of pyrolysis conversion of waste tires and plastics. The core of the paper is the determination of energy properties of noble fuels obtained from pyrolysis conversion and the possibility of their real use in industry. The aim of this paper is a technical-economic evaluation of the use of waste pyrolysis in practice in the Slovak Republic. Unlike various methods of waste management, there are also more efficient methods, which primarily have a positive effect on the ecology of our Earth and at the same time can be effectively used for the production of alternative fuels. One of these methods is the pyrolysis conversion of synthetic waste materials into noble fuels. It is an ecological, waste-free, economical, and economical disposal of waste with a full recovery of its energy and material components with reduced emissions, and therefore this direction of using synthetic waste for the conversion of alternative fuels contributes to sustainable development. A significant advantage of this waste management is considered to be the fact that only waste tires or chlorine-free plastics are used as input materials without other necessary raw materials obtained by other economic activity. Tires and plastics are generated daily as waste in every household.

“…Although the kinetics of pyrolysis packaging plastics (PS/PP, PET/PP, PET/PE film and PP/PE film) was studied thoroughly using different kinetics models [ 31 , 32 , 33 ], only one study was focused on pyrolysis kinetics of MFPWs using model-free methods (as the simplified formal reaction model) [ 11 ], which resulted in big variation in the kinetic parameters at the lower conversion rate (up to 0.7) and unreasonable kinetic parameters at the higher conversion rate. Additionally, it was assumed that by using this model each peak in the DTG analysis curves corresponds to the individual and sequential decomposition of the pseudocomponents, giving the impression that no interactions occur between them [ 34 ].…”

Modeling of Metalized Food Packaging Plastics Pyrolysis Kinetics Using an Independent Parallel Reactions Kinetic Model

Recently, a pyrolysis process has been adapted as an emerging technology to convert metalized food packaging plastics waste (MFPWs) into energy products with a high economic benefit. In order to upscale this technology, the knowledge of the pyrolysis kinetic of MFPWs is needed and studying these parameters using free methods is not sufficient to describe the last stages of pyrolysis. For a better understanding of MFPWs pyrolysis kinetics, independent parallel reactions (IPR) kinetic model and its modification model (MIPR) were used in the present research to describe the kinetic parameters of MFPWs pyrolysis at different heating rates (5–30 °C min−1). The IPR and MIPR models were built according to thermogravimetric (TG)-Fourier-transform infrared spectroscopy (FTIR)-gas chromatography−mass spectrometry (GC-MS) results of three different types of MFPWs (coffee, chips, and chocolate) and their mixture. The accuracy of the developed kinetic models was evaluated by comparing the conformity of the DTG experimental results to the data calculated using IPR and MIPR models. The results showed that the dependence of the pre-exponential factor on the heating rate (as in the case of MIPR model) led to better conformity results with high predictability of kinetic parameters with an average deviation of 2.35% (with an improvement of 73%, when compared to the IPR model). Additionally, the values of activation energy and pre-exponential factor were calculated using the MIPR model and estimated at 294 kJ mol−1 and 5.77 × 1017 kJ mol−1 (for the mixed MFPW sample), respectively. Finally, GC-MS results illustrated that pentane (13.8%) and 2,4-dimethyl-1-heptene isopropylcyclobutane (44.31%) represent the main compounds in the released volatile products at the maximum decomposition temperature.
