The effect of temperature and steam concentration on the yields of different tar compounds was investigated. Wood pellets and dried sewage sludge spheres (DSS) were pyrolyzed in a fluidized bed reactor in the temperature range of 500-800ºC. The reactor has two independent electrically heated zones, enabling independent adjustment of the temperature of generation of volatiles (release of volatiles during thermal decomposition of the fuel particle) and secondary conversion of the volatiles on homogeneous phase. The...
