“…Increasing steam/tyre mass ratio in a rotary kiln reactor had a positive effect on enhancing CO and hydrogen content in gas products [67]. Various agents such as steam, air/CO 2 , and air/steam can be used in tyre gasification processing; steam resulted in a low heating value gas of 15.21 MJ·m −3 [68]. In regards to increasing temperature in tyre gasification, gas production is enhanced [69].…”

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.

“…Gasifying agent is a crucial factor affecting gas quality [23,33] and in this study, dry and moisture saturated air are used to evaluate the effect of the existence of steam on ISW gasification performance. By comparing the results of cases #1 and #5 given in Table 4, we could notice that the addition of steam not only increased gas LHV from 6.70 to 8.21 MJ/Nm 3 , but also strongly enhanced carbon conversion efficiency from 71.70 to 84.56%.…”

“…They have reported the yield of H 2 and CO contents and higher heating value (HHV) of the syngas produced from char gasification increases with pressure. Karatas et al 39 performed the gasification studies of waste tire using air and CO 2 , air and steam, and steam in a bubbling fluidized bed gasifier. They have reported that the average lower heating value (LHV) of the product gas was 15.21 ± 0.98 MJ/(N m 3 ).…”

The energy recovery from carbonaceous materials is considered a reliable energy source. In this context, pyrolysis, combustion, and gasification characteristics of scrap truck and car tire samples were investigated using a thermogravimetric analyzer coupled with mass spectrometer system. Pyrolysis behavior of the sample was estimated in argon atmosphere with the heating rate of 40 K/min over the temperature range of 100−1100°C. The combustion and gasification studies of the tire samples were conducted in oxygen and steam ambiences, respectively. In addition, the size effect of the truck tire has been examined. The ignition temperature, temperature of maximum mass loss rate, and burn-out temperatures of both truck and car tires were measured. The pyrolysis gas mainly consisted of hydrogen, hydrocarbons, and carbon oxides, whereas in the condensable gases (pyrolytic liquids) mainly aromatic hydrocarbons and alcohols were detected in the temperature range of 300−500°C. In the combustion processes, mostly CO and CO 2 gases were released; besides some hydrocarbons were also evolved. Moreover, the release of sulfur compounds and nitrogen oxides were detected in pyrolysis and combustion stages, but the nitrogen oxide was predominant in the later stage. The complete gasification conversion of scrap tire is taking place at 950°C during the isothermal condition in steam ambience. The main products detected during gasification were CO 2 , CO, and H 2 , indicating that oxidation, water gas, and water gas shift reactions were predominant. The emission of sulfur compounds during combustion and gasification reactions implied the presence of sulfur in pyrolyzed char. The results indicated that the scrap tires can be used as a potential energy resource. The activation energy (E a ) was calculated from the thermogravimetric test results by using an Arrhenius-type kinetic model.
