Abstract
The present work studies the possibility of energy recovery by thermal conversion of waste tires, a potential feedstock for combustion and gasification processes. Considering the difficulties of using these residues in isolation, cocombustion and co-gasification tests with acacia and miscanthus biomass were carried out in order to assess the characteristics of these residues as a fuel for thermochemical processes. Co-gasification tests were run in a fixed bed reactor at temperatures of about 800 °C. The results obtained demonstrate the viability of the technology, with the ideal conditions for the production of syngas with higher LHV (3.64 MJ/Nm3) occurring in mixtures with 20% of waste tires. As for co-combustion, tests were performed in a pyro-tubular multi-fuel boiler with temperatures ranging from 400 °C to 500 °C. With respect to gaseous emissions (NOx, NO, and SO2), it was verified that increasing the percentage of tires in the mixture resulted in increased emissions of pollutant gases. These results present a problem since the obtained values are higher than those allowed by the Portuguese law. It was also concluded that gasification is a perfectly adjusted technology for the valorization of waste tires, being able to transform them into a fuel for energy recovery derived from residues with no other use.
