“…However, for similar pyrolysis conditions, Banar et al (2012) reported that for pyrolysis of tyre derived fuel (steel removed) the maximum oil yield was only 38.8 wt.%, with char yield at 34 wt.% and a high gas yield of 27.2 wt% for a heating rate of 5°C min -1 at a pyrolysis temperature of 400°C. A similar oil yield of 38.0 wt% at the pyrolysis temperature of 500°C and 15°C min -1 heating rate was obtained by Laresgoiti et al (2004) and de Marco et al (2001). Rada et al (2012) also obtained an oil yield of 40 wt.% and gas yield of 20 wt.% and char yield of 40 wt.% for the fixed bed batch pyrolysis of tyres.…”

“…Concentrations of total PAH in tyre pyrolysis oils are reported at 1.72 wt% for a fixed bed reactor at 500°C (Cunliffe and Williams, 1998a), however, higher concentrations of PAH totalling over 16 wt.% have been reported for the rotary kiln pyrolysis of waste tyres at the same temperature (Li et al, 2004). A wide range of PAH have been reported by Laresgoiti et al (2004), consisting of mainly naphthalene, fluorene and phenathrene and their alkylated homologues.…”

Pyrolysis of waste tyres: A review

2013

View full text Add to dashboard Cite

Approximately 1.5 billion tyres are produced each year which will eventually enter the waste stream representing a major potential waste and environmental problem. However, there is growing interest in pyrolysis as a technology to treat tyres to produce valuable oil, char and gas products. The most common reactors used are fixed-bed (batch), screw kiln, rotary kiln, vacuum and fluidised-bed. The key influence on the product yield, and gas and oil composition, is the type of reactor used which in turn determines the temperature and heating rate. Tyre pyrolysis oil is chemically very complex containing aliphatic, aromatic, heteroatom and polar fractions. The fuel characteristics of the tyre oil shows that it is similar to a gas oil or light fuel oil and has been successfully combusted in test furnaces and engines. The main gases produced from the pyrolysis of waste tyres are H 2 , C 1 -C 4 hydrocarbons, CO 2 , CO and H 2 S. Upgrading tyre pyrolysis products to high value products has concentrated on char upgrading to higher quality carbon black and to activated carbon. The use of catalysts to upgrade the oil to a aromatic-rich chemical feedstock or the production of hydrogen from waste tyres has also been reported. Examples of commercial and semi-commercial scale tyre pyrolysis systems show that small scale batch reactors and continuous rotary kiln reactors have been developed to commercial scale.

“…The best scenarios for the energy conversion of ST by pyrolysis requires a temperature of 430 °C, a constant 0.35 m 3 /h nitrogen flow, and a 10 mm TDF [47,48]. TDF sizing from 1 to 3 cm transforms high caloric (68-84 MJ/m 3 ) VOC's into high caloric syngas with very low CO, CO 2 , and H 2 S content [49,50]. When used motor oil [30], sawdust [50], and municipal solid wastes [51] are mixed with TDF during pyrolysis, the caloric value of the result ing syngas increases.…”

Energy Recovery from Scrap Tires: A Sustainable Option for Small Islands like Puerto Rico

Puerto Rico generates and disposes nearly five million/year scrap tires (ST), of which 4.2% is recycled and 80% is exported. The Island has one of the world highest electrical service tariff ($0.28 kWh), because of its dependency on fossil fuels for power generation. The Government has not considered ST for electricity production, despite more than 13,000 ST are generated daily, and paradoxically exported for that purpose. Theoretically, if ST recycling increases to 10% and assuming that the caloric value of ST be 33 MJ/kg, it was estimated that scrap tires processed with pyrolysis can supply annually about 379 MWh, a potential value that shall not be unnoticed. This paper is a literature review to describe the legal, technical, and economic framework for the viability of ST for power generation in Puerto Rico using pyrolysis, the most recommended process for ST energy recovery. Data of ST from Puerto Rico was used to model the potential of ST for pyrolytic energy conversion. The herein article is intended to invite other insular countries and territories, to join efforts with the academic and scientific community, and with the energy generation sector, to validate ST as a sustainable option for energy generation.
