Construction woody waste is one of precious energy resources. In this paper, we reports the experimental results of air gasification conducted using a two-stage gasifier that consisted of a fluidized bed zone (bottom-reactor) and a tar cracking zone (upper-reactor) filled with activated carbon. In the experiments, the effects of the experimental variables such as the equivalence ratio, upper-reactor temperatures and fluidization velocity were investigated. In addition, the results of the experiments with virgin, without and...
