“…Researchers have attempted to advance this technology to make it technically and economically feasible and applied to produce biofuel from various feedstocks. Tyre pyrolysis has been the subject of many studies; a major reason is it is environmentally friendly and its lower emission except for a few equipment leakage and minor fugitive sources [75][76][77][78][79][80][81]. Biomass pyrolysis is a very complex process and performed in two stages.…”

Abstract:This article provides a review of different methods for managing waste tyres. Around 1.5 billion scrap tyres make their way into the environmental cycle each year, so there is an extreme demand to manage and mitigate the environmental impact which occurs from landfilling and burning. Numerous approaches are targeted to recycle and reuse the tyre rubber in various applications. Among them, one of the most important methods for sustainable environmental stewardship is converting tyre rubber components into bio-oil. In this study, scrap tyre management techniques including landfill, retreading, recycling, combustion, and conversion to liquid fuels was reviewed (including gasification, hydrothermal liquefaction, and pyrolysis). The effects of parameters such as reactor types, pyrolysis temperature, and catalyst on the oil, gas and solid products in pyrolysis process were investigated.

“…The sulfur content in tires is 1-2% [27]. Several studies have focused on the migration and transformation of sulfur elements during the pyrolysis process [28][29][30]. From the above experimental data analysis, it can be seen that the sulfur content in pyrolysis gas was negligible.…”

Experimental Study on Spent FCC Catalysts for the Catalytic Cracking Process of Waste Tires

Research on the synergistic high-value reuse of waste tires and used catalysts in spent fluid catalytic cracking (FCC) catalysts was carried out in this study to address the serious ecological and environmental problems caused by waste tires and spent FCC catalysts. The experiment, in which a spent FCC catalyst was applied to the catalytic cracking of waste tires, fully utilized the residual activity of the spent FCC catalyst and was compared with a waste tire pyrolysis experiment. The comparative experimental results indicated that the spent FCC catalyst could improve the cracking efficiency of waste tires, increase the output of light oil in pyrolysis products, and improve the quality of pyrolysis oil. It could also be used for the conversion of sulfur compounds during cracking. The content of 2-methyl-1-propylene in catalytic cracking gas was found to be up to 65.59%, so a new method for producing high-value chemical raw materials by the catalytic cracking of waste tires with spent FCC catalysts is proposed.

“…Liquid products contain many types of sulfur containing compounds of which the main groups were thiophenes, benzothiazoles, benzothiophenes, dibenzothiophenes, and their alkylated derivatives while minor groups were also found such as naphthothiophenes, benzonaphthothiophenes, and their alkylated derivatives [1,[5][6][7]. In the main groups of sulfur containing compounds, main species found in the reports as mentioned above were 2-methylthiophene, 3-methylthiophene, 2,3-dimethylthiophene, 2,5-dimethylthiophene, 2-ethylthiophene, dibenzothiophene, methyldibenzothiophenes, dimethyldibenzothiophenes and trimethyldibenzothiophenes.…”
