“…It is a thermal decomposition of solids usually at a typical temperature range of 300°C–600°C in the absence of oxygen to yield pyrolytic oil, char, and noncondensable gas (Miandad et al., 2017). The pyrolysis oil produced is known to have comparable properties and composition to the petroleum‐derived fuels, and its combustion does not emit hazardous and greenhouse gases (Li & Wei, 2016; Odejobi et al., 2020b; Zhang et al., 2018).…”

The combined mixture process variable approach for optimization and prediction of oil yield in co‐pyrolysis of polymeric wastes was investigated in this study using I‐optimal design. The components mixture investigated were low‐density polyethylene (LDPE), polystyrene (PS), and polyethylene terephthalate (PET), whereas the process variables were temperature and residence time. Thirty experimental runs were developed using the I‐optimality criterion to investigate the effect of interaction between the mixture and process parameters on oil recovery from co‐pyrolysis of the polymeric wastes. The data obtained were used to generate a model equation, and analysis of variance was used to estimate the significance of the model. The model was significant with a P value < 0.0001, the R2 value of 0.9980, adjusted R2 of 0.9949, and predicted R2 of 0.9201. Optimized oil yield showed close match between actual and predicted responses with a desirability factor of 0.999. The predicted mixture compositions and operating parameters for the optimum oil yield were 52.86% for LDPE, 47.15% for PS, and 0% for PET at 471.07°C and 115.25 minutes. The chemical compositions of the pyrolysis oil at the optimum conditions were hydrocarbons in the carbon range between C6 and C25, with physical properties comparable to conventional diesel.

“…High-density fuel will affect engine performance and trigger increased emissions of gases such as carbon monoxide (CO) and soot from carbon dioxide (CO2). High fuel viscosity will induce ignition delay, meanwhile, low viscosity fuels are ideal for contributing to pump pumpability and engine efficiency [18][19]. Another important parameter of TPO as a fuel is the higher heating value (HHV).…”

The increasing production of automotive vehicles has led to a significant increase in the rate of waste tire generation. Approximately 160 tons/day of waste tire are produced in Bandung City which will eventually become an environmental problem. However, the pyrolysis process can be applied as a technology to treat waste tire to produce valuable hydrocarbon products. This study addressed the description effect of used tire waste on the yield, properties, and composition of tire pyrolysis oil (TPO) products. The effect of zeolite catalysts on TPO was also studied. 500 g of the waste tire was pyrolyzed using a small tube reactor containing a zeolite catalyst at various temperatures of 300-450 °C for 60 minutes. From the present work, the highest TPO product yield of 36.6 %-wt was obtained during the pyrolysis of the waste tire. The characteristics of TPO as a fuel, such as viscosity and density are close to those of gasoline fuel with a heating value of about 44 MJ/kg. The compounds contained in TPO were classified into hydrocarbon groups compounds as commercial fuel which are included as compounds of aromatics, paraffin, naphthenes, and cycloparaffins through the results of GC-MS spectrum analysis. The TPO from waste tire pyrolysis is on par with the hydrocarbon range of gasoline (C7-C11).

“…Waste tires consist of high-polymer compounds, and many studies have researched the methods of processing waste tires in an environmentally friendly and efficient manner. Pyrolysis is considered to be the greenest and the most efficient process that allows the production of fuels and chemicals from waste tires, and in this respect, pyrolysis of waste tires is defined as thermochemical decomposition of organic compounds present in waste tires [14][15][16][17].…”

The increasing global population and the rapid industrial development associated therewith have increased the demand for fossil-derived fuel oils. The sources of fossil fuels are limited, and many studies have been being conducted to find alternative fuel sources. Waste tire pyrolysis oil (WTPO) attracts considerable attention as an alternative fuel because its properties are similar to those of diesel oil. However, WTPO has a high sulfur content of >1.0 wt%, which is above the environmental standard limit of 0.1 wt%; therefore, it cannot be used in engines directly. It is thus highly necessary to remove sulfur compounds from tire-derived oils. However, finding an appropriate and environmentally friendly process is proving difficult. This review article presents the various desulfurization methods used to removal sulfur from WTPO, such as hydrodesulfurization (HDS), oxidative desulfurization (ODS), ultrasound-assisted oxidative desulfurization (UAOD), and acid treatment. Of these, HDS is the most expensive as it involves high consumption of hydrogen, high temperature (~450 °C), and high pressure (~200 bar), whereas UAOD is an efficient and economic method of reducing the sulfur content of WTPO.
