“…Al-Lal et al [15] carried out their research on desulfurization of pyrolysis fuels obtained from waste. In this work, they used two affordable desulfurization techniques without hydrogen to reduce the sulfur content of these three pyrolysis fuels with moderate success that could make them useful as heating fuels.…”

The standard of living, quality of life, and development of a nation depend on its per capita energy consumption. Global energy supply that mainly depends on fossil fuel is decreasing day by day. It is estimated that the energy demand will be increased five times by the year 2021 from present scenario. Due to the fossil fuel crisis, the development of alternative fuel technologies has drawn more attraction to deliver the replacement of fossil fuel. Pyrolysis is one of the promising alternative fuel technologies which produces valuable oil, char, and gas product from organic waste. Early investigations report that tire pyrolysis oil extracted from vacuum pyrolysis method seemed to have properties similar to diesel fuel. The main concern of this paper is to produce and improve the properties of crude tire pyrolysis oil by desulfurizing, distilling, and utilizing it with diesel in CI engine to analyze the efficiency for various compositions.

“…The amount of sulfur found in tires is between 0.5 and 2.0 wt%, i.e., less than or equal to most quantities in coal and petroleum coke in general, while that observed in TPO is between 1.0 and 1.4 wt% which make a necessary posttreatment to avoid the formation of SOx [26,27]. The same occurs with hydrocarbons that constitute tire rubber, which are no more complex or difficult to be destroyed than those present in coal [24,28,29].…”

This manuscript aims to study the atomization and characterization of tire pyrolysis oil (TPO); thus, Y-Jet atomizers have been designed and manufactured by using an experimental bench, which was specifically built for such a purpose. The droplet size was measured experimentally and compared with the theoretical value obtained with the equation proposed by Wigg. The potential for production of TPO in Brazil from tires discarded for 2016 was approximately 190 million liters and in the world for the same year was 4160 million liters; these values represent an excellent alternative for the energetic use of these oils as well as a good way to valorize the by-products obtained from tire pyrolysis such as char and tire gas. The TPO can be used in combustion processes in pure form or mixed with other renewable or non-renewable fuels, so it is important to study atomization processes that guarantee an excellent quality of combustion. The spray quality generated by atomizing pure TPO and in blends (TPO-diesel) has been quantified by droplet size measurement through the Spraytec Malvern 2007 laser diffraction system, whose main properties have also been measured, such as density, viscosity and surface tension of pure liquid fuels and blends, liquid and gas flow pressure at the atomizer nozzle, and droplet size distributions generated by the atomized jet for different gas/liquid ratio values. The influence of the point where liquid pressure exceeds gas pressure at the atomizer nozzle, as well as the TPO percentage effect on droplet size, is demonstrated, and a comparison of experimental droplet size with the one which had been theoretically calculated by Wigg's equation is made. The study of the atomization of TPO, pure and blends, allows to know a favorable condition for its burning and provides a suitable destination for discarded tires. For a better characterization of the spray, the atomization cone angle was also measured for all the mixtures.

“…The property of the oil is presented in Table 10 [4,19,44,83,84]. The standard analysis concerned with the determination of properties of tyre-oil is given in Table 4 [1,4,15,16,42,47,83,[85][86][87][88]. The oil can be directly used as fuel in furnaces, steam boilers, gas turbines, IC engines, etc.…”

Abstract−Waste tyres have become a grave concern as their accumulation is aggregating every year. Not only the size of waste tyre has to be reduced, but also some useful energy has to be recovered out of it as the world badly requires energy from alternate sources. Pyrolysis is one such method to extract energy potential products from waste tyres. It is extensively used to generate carbon black (solid product), tyre-oil (liquid product) and syngas (gas product) from waste tyres. In that connection, this article discusses the effect of various parameters on the product composition of pyrolysis of waste tyres. The current usage of pyrolysis products and their typical characteristics are also discussed in this critique. Of late, extraction of high value added products, such as activated carbon from carbon black, and limonene from tyre-oil is gaining attention. The article also throws some light on the application and generation routes of activated carbon and limonene from waste tyres.
