[Gasification characteristics of waste tires in laboratory-scale fluidized-bed gasifier].
A laboratory-scale fluidized-bed gasifier was designed and used to investigate the characteristics of waste tires gasification. Granulated tires were gasified with different excessive air ratios at a temperature range of 400-700 degrees C. The gasification efficiency, carbon conversion efficiency, heating value, yield and components of syngas were analyzed. Results showed that the optimum operation conditions were achieved when the gasification temperature was 700 degrees C and the excessive air radio (EAR) was 0.4. A gaseous product, mainly containing CH4, CO, H2, C2H6, and longer-chain hydrocarbon with a lower heating value (LHV) of about 4804 kJ/m3, can be generated at the highest gasification efficiency of 47.96% under the optimum operation conditions.
