FATE OF PAHS IN AN AUTOFLUFF INCINERATION PROCESS

The autofluff (auto shredder residue) is far more difficult to be trea ted effectively At present, only landfilling of autofluff is practiced on a large scale, and its cost is rising rapidly and the acceptance o f this method is decreasing. In the nearly future, incineration of aut ofluff would be an economically attractive alternative. The autofluff wastes contains at least 5 wt% of Cl. An important question is whether the destruction of these wastes leads to the formation of other hazar dous matters. Of the main concern are the PAHs. In the steady-state op eration of the autofluff incineration process, major constituents of P AHs were emitted via the stack. We found that the mass growth of PAHs involves a sticking rings collisions routes at 910-1050 degrees C, Exp erimentally, addition of BghiP to particles does increase the size or amount of particles.
